The Future of Diesel is Low CO2 Synthetic Fuels

The stew of molecules your diesel is made of has been changing. A next level technology in chemistry is enabling garbage to be transformed into hydrocarbon fuels like diesel, jet fuel, naphtha, and propane as well as other high value chemicals. These technologies enable petroleum refineries in the United States to retool themselves and move into making biofuels with the very technology used to refine modern gasoline and diesel fuels from crude oil.  Currently oil refineries take crude petroleum and crack the molecules and reform them with a hydrotreater.  This hydrogenation is what makes renewable diesel from fats, oils and greases.

If you have ever worked under your sink at home. Remember the greasy mess inside the pipes below your kitchen sink.  These renewable hydrogenation technologies can turn that trash into a super clean high performance synthetic diesel fuel.  That waste stream along with used deep fryer oil, the animal fats from rendering and other sources is the feedstock for renewable diesel.  It is exciting and this will be the future of our diesel and jet fuels.  These fuels also have a fraction of the CO2 footprint of a fossil fuel equivalent as measured by Oregon, Washington or California’s rules to measure the carbon intensity of fuels.

Diesel Fuel in Oregon and Washington

Star Oilco has been getting questions on the changes of diesel in Portland, Oregon.  If you have not noticed, many diesel pumps at retail gas stations and cardlock have seen changing stickers on the face of the fuel pumps.  As of July 1st, 2024 the City of Portland requires a minimum 15% biofuel content of all diesel sold.  This policy is called the Portland Renewable Fuel Standard.  Portland currently plans to ramp up this requirement to a 50% biofuel blend in May of 2026.  So that every gallon of diesel sold inside the City of Portland must be half biomass based diesel products blended with fossil diesel.

This has caused quite a few changes in what fuel pumps have as their fuel for sale.  Usually people notice this change with teh color of the diesel coming out of the retail nozzle.  Diesel fuel buyers are noticing the bright yellow color of B20 biodiesel, the fully clear color of Renewable Diesel or a mix of several fuels tinting the color of their diesel.  This trend is bigger than just Portland.

Today on the west coast there are a variety of product label stickers you will see on diesel pumps.  These show the variety of diesel fuel specifications that are being sold to diesel vehicles today. Blends of petroleum ultra low sulfur diesel, R99 (99%) renewable diesel, and B99 (99%) Biodiesel are combined to meet the market needs of the diesel we all buy.

This change is because of a combination of pure market forces, government rules and local decisions by fuel haulers.  Today’s diesel not only has a commodity market for the fuel it also has a market for CO2 credit value and a cap of total petroleum diesel fuel that can be sold into a west coast state with a “Cap and Investprogram requiring blends of low CO2 biofuels, the liquid fuels sold for vehicles.

Add on top of these market forces, advances in technology used to make the liquid diesel fuel.  The diesel arriving at truck stops, gas stations, cardlock or out of a hose from a bulk truck has been changing and it’s often in good ways.  Knowing how can be helpful in navigating why diesel may cost one price or another and may have a need or maintenance that another fuel does not.

THE RISE OF RENEWABLE DIESEL

Renewable diesel, also called R99 as in 99% renewable diesel, is a synthetic diesel fuel made from the same feedstock as biodiesel. The big difference though is that renewable diesel’s finished product is hydrocarbon diesel.  Biodiesel chemically is not a hydrocarbon or made up of diesel molecules.  Renewable diesel is a biofuel, but it is also chemically diesel on a molecular level. For fuel regulation they refer to it (as well as biodiesel) as “Biomass Based Diesel” for labeling at the fuel pump.

There have been billions of plant capacity brought online in the United States for renewable diesel.  During the COVID market drop in fuel prices a number of petroleum refineries shut down, then upgraded their technology to make hydrocarbon diesel fuels out of the very biobased fats, oils, and greases biodiesel is made from.  These refineries use hydrotreating technology just like they do with a crude petroleum to make an actual hydrocarbon diesel molecule.   With this technology adoption to make diesel and jet fuels from vegetable oils and animal fats billions of gallons of low CO2 diesel fuels are coming on the market and governments are requiring it’s use, such as Portland’s Renewable Fuel Standard.

THE AVAILABILITY OF BIODIESEL

The US makes billions of gallons of biodiesel.  A fuel that’s quality and performance continues to improve.  If you are not a fan of biodiesel in your fuel thinking strategically about the fuel will likely benefit your fleet operation.  The big concern with diesel fuel in a ultra low sulfur world is water and dirt suspended in the fuel affecting the performance of diesel emission systems.  With clean and drier quality specifications of B99 blend stocks today versus a decade ago the use of this fuel has grown substantially especially in the truck stop market.

When crude petroleum prices are high and therefore refined diesel prices are equally as high biodiesel is often an extremely competitive fuel.  Recently changes in Federal subsidies on biodiesel have changed this market dynamic a bit but you can presume that biodiesel will often be sold at a discount against fossil fuel diesel.  If a large seller of diesel (including petroleum refiners) can pick up pennies per gallons on millions of gallons sold they will do so.  Therefore Biodiesel is often seen in diesel in small blends even if you do not see a label on retail pump.  For blends above 5% a label is required for retail fuel sales.

Above are a variety of labels used to denote what fuel blend is coming out of a retail diesel dispenser. Feel free to call Star Oilco at 503-283-1256 if this confuses you and you want it explained.  We would be glad to do so.

These labels can be found together often at one pump.  All state and Federal standards require ultra low sulfur diesel for any on-road diesel sale.  The Federal standards also adopted by the states require a disclosure at the fuel pump if a blend is above 5% biodiesel.  The max allowable blend of biodiesel for diesel truck manufactures is a 20% blend.  If a truck dealership says that you cannot blend biodiesel up to 20% they need to take that up with the Federal Government because they need to support it.  This is why the label shows a blend may contain between 5% and 20% biodiesel content.

Renewable diesel is a hydrocarbon diesel. 

 

It is diesel meeting the ASTM D975 specification for diesel. 

Retailers selling blends of R99 in their fuel do not need to label it given this.  They still do label it given the benefits of the fuel’s performance and that customers are seeking that fuel.

Many retail places will have stacked labels showing they may be blending 5% to 20% biodiesel as well as may be adding R99 Renewable Diesel to the fuel as market conditions dictate it is the more cost competitive fuel.  When seeing a label like this it can usually be assumed they are blending a R80 (80% Renewable Diesel) and a B20 (20% Biodiesel) blend of fuel.  This blend is actually believed by some to be a higher performing fuel seeing better performance that a R99 or B20 fossil fuel blend.

Fossil fuel diesels are being replaced or blended with biomass based diesels.  Be it Renewable Diesel or Biodiesel.  These blends are driven by more than one industry requirements, government rules, or other market forces. One of these being Portland’s banned on petroleum diesel through the Renewable Fuel Standard (RFS). This is resulting in an increase of low-carbon biofuel blends that will ultimately move to a mix of 99% renewable fuel requirement by 2030.

Renewable Diesel and Biodiesel Blend fuel dispenser label.

The big drivers are industry specification for fuels (both labeling as well as chemical characteristics), state rules on selling these fuels, their quality assurance as well as CO2 content, and of course the market forces.  Market forces being the supply and demand availability of fuel needed to meet customers.  Less fuel available to sell means higher prices for customers.

A decade ago the market for diesel was far simpler. Though you had biofuels and some blend mandates basically you had a diesel specification accepted and the daily price as tracked by a lighted retailers sign, a wholesale market average or spot buying by some customers.   Today this market is far more complicated by government regulation on the west coast.  There are three big programs at state levels impacting this.

State Fuel Rules cause a unique need for one state or another. Whereas twenty years ago if Oregon or Washington fuel was selling for more than the Gulf Coast you might see brokers bring fuel into the region then driving down high prices.  With the creation of various complex and unique rules on diesel, imports of fuel to these low CO2 fuel states has dropped.  The amount of people moving product into west coast states has dropped.  The big rules causing this are the Cap and Invest programs of the West Coast states, the Low CO2 Fuel Standards of the states, and the fuel blend mandates of various jurisdictions of these states. For instance California now requires all off-road diesels but 99% renewable diesel.  Portland, Oregon also has a CO2 requirement and minimum 15% blend of biomass based diesel on all fuel sold in the state.

WHAT ARE THE DIESEL FUELS AND THEIR SPECIFICATIONS

Petroleum Diesel:
ASTM D975 Specification.

The ASTM D975 is a series of tests used to maintain consistent industry standard product performance for diesel fuel.  It includes among several tests cloud point, cold filter plug point (CFPP), several masurements of diesel fuel operability performance, intrained water content, sediment, carbon residue, ash, distillation, viscosity, sulfur, copper corrosion, cetane number, cetane index, aromaticity, and conductivity.

Renewable Diesel:
ASTM D975 Specification.

Renewable Diesel is following the same series of tests as petroleum refined diesel fuels.  It is the same ASTM D975 specification. Though Renewable Diesel has some different properties that exceed the ASTM specification of diesel.  Renewable Diesel is highly prized as a fuel because it typically is a cleaner and drier diesel fuel than petroleum diesel. This being seen by the tests on sediment and water content in a parts per million level.  Renewable Diesel content in diesel fuel can also be tested for looking for a C14 molecule (the chain typically created in a Hydrotreated Diesel process from fats, oils and greases.

Biodiesel (Methyl Esther):
ASTM D6751 Specification.

The ASTM for Biodiesel tests a mono-alkyl esters of long chain fatty acids derived from vegetable oils and animal fats. The testing for quality assurance covers an analysis for flash point, methanol, water and sediment, kinematic viscosity, sulfated ash, oxidation stability, sulfur, copper strip corrosion, cetane number, cloud point, acid number, carbon residue, total and free glycerin, phosphorus, reduce pressure distillation temperature, atmospheric equivalent temperature, combined calcium and magnesium, and combined sodium and magnesium.

For more on Biodiesel Use and Handling the National Renewable Energy Laboratory has a great book on the subject.

THE HISTORY OF DIESEL FUEL SPECIFICATIONS IN THE UNITED STATES

In the 1990’s the US EPA passed rules that demanded a phase out of sulfur in diesel fuel.  The presence of sulfur was very good for the fuel’s storage stability as well as fuel lubricity, but was horrible for air quality.   Additionally the big smog contributor was NOx (nitrous oxide) which was one of the EPA’s reason’s for pulling sulfur out of diesel.  For the EPA to get engine manufacturers to treat the NOx emissions at the tailpipe they needed all the sulfur gone (ultra low sulfur diesel) for modern diesel emission systems to be able to eliminate NOx as well as a host of other pollutants including particulates.

The story of changing diesel fuel standards in the US under the EPA is one of removing sulfur from our diesel fuel.  In 1996 the fuel refiners and sellers of diesel had to move the sulfur content of the fuel sold for on-road purposes to below a 500 parts per million standard. Commonly referred to as Low Sulfur Diesel fuel.   In 2006 the standard moved to a maximum of 15 parts per million of sulfur for all on road fuels.

In 2006 while the sulfur content of fuel was dropping the City of Portland released the first mandated blend of biodiesel content.  This being a 5% biodiesel blend.  The next year, the State of Oregon followed with its own Renewable Fuel Standard requiring this throughout the state.  This began the expectation of biodiesel in most diesel fuel in the Portland, Oregon area.  Washington also passed a similar policy for blending biodiesel but the enforcement and need for the fuel is less specific at Washington fuel pumps.

Make And Keep Your Diesel Fuel Much More Clean

                               Make And Keep Your Diesel Fuel A Lot More CleanClean, dry, premium diesel

What is Clean Diesel? 

Clean diesel is free of the contaminants that harm modern diesel engines. Today, there is a gap between ASTM diesel standards and the ISO cleanliness standards needed for use in high pressure common rail engines. Anyone operating a modern clean diesel engine is seeing the effect, including injector replacement, DPF regeneration, and a host of other fuel quality related maintenance concerns we never saw twenty years ago. On top of all of that, today’s refined diesel fuels are less storage stable than ever before. What is on the bottom of your bulk tank can also complicate matters further. When diesel is bought wholesale, it typically meets and exceeds ASTM required industry standards, but almost always requires additional filtration to avoid excessive engine wear and premature part failures.

Having clean diesel requires an additional amount of care. Namely, you need to make sure that the fuel is aggressively filtered at 4 microns to catch the microscopic particles that are big enough to damage your modern diesel engine’s high pressure fuel rail system. Furthermore, clean diesel is fuel that is free of water and stabilized with Premium Diesel to guarantee no bacteria, yeast and other creatures can grow and further contaminate the saddle tanks on your trucks.

For more on clean diesel, see Donaldson’s description of “The New Clean” for an in-depth explanation of what ISO cleanliness and filtration mean for your diesel fleet.

Making Diesel Cleaner!

Knowing the quality of your fuel is the first step. This is done by taking samples off of the bottom of your bulk storage, as well as a representative sample from your fuel dispenser. Lab tests of those samples will tell you if you have water, biological growth, or dirt issues with your storage. The contaminants in the tank being sampled are almost always visible, which is to say that they look horribly ugly. If your fuel quality assurance has been on autopilot, do not be surprised if you find this. After gathering knowledge about your fuel, the next step is to get your fuel quality clean.

Filtration and tank bottom sampling is the start. Beyond that, the only way to improve your fuel quality performance is to filter your fuel, ensure water is not getting into the tank through condensation, and additize it with a Premium Diesel additive to upgrade the performance of the fuel. Many fleets today are seeing injector wear and continual problems with particulate trap maintenance. This is a combination of water in fuel and microscopic particles not captured by a 10 or 30 micron filter used at most diesel dispensers. You have to filter more aggressively than this.

Clean, Dry, and Premium Diese

Where To Start?

The first step is sampling your bulk diesel tank. We check your bulk tank for water and dirt to make sure and meet the specifications your engine is built for. Star Oilco can help by providing a complementary diesel test for those fleets interested in taking control of their fuel quality assurance. Usually when testing fuel, we take a sample off of the tank bottom as well as a representative sample out of the fuel dispensing nozzle.

What we usually find is ASTM specification diesel fuel (it meets ASTM spec) that is higher than you’d want (still in spec) for water with far more dirt than the OEM’s would want to see in your engine. This dirt fails to be within the “ISO Cleanliness” specifications recommended by engine manufacturers. Usually, we also see water on the bottom of the fuel tank, which is a likely source for future or current biological growth in your fuel tank.

Star Oilco can help you fix this! The first step is to sample your fuel tank.

NOTE: If you have a current biological growth problem in your bulk fuel tank or fleet, your first step is to treat that effected fuel with a diesel microbiocide to kill the bugs growing in your tank. For more on this, see our Valvtect Plus 6 Diesel Microbiocide page.

Oregon: The Next Generation Of Diesel

B99 and R99 Biofuels are the alternatives to petroleum diesel in Oregon

Oregon bans the sale of petroleum diesel, a rapid transition to biofuels such as renewable diesel and biodiesel are happening.

 

Oregon HB3305 explained

 

 

HB 3305 Petroleum Diesel ban

In Oregon, HB3305 is a House Bill proposed by Representative Karin Power outlaws the sales of petroleum diesel to the public for use in motor vehicles.  HB3305 quoted below:

“Prohibits retail dealer, nonretail dealer or wholesale dealer from selling petroleum diesel for use in motor vehicle on or after specified dates. Requires public improvement contract to require that motor vehicles be powered by fuel other than petroleum diesel. Prohibits public body from using petroleum diesel in motor vehicle under control of public body”

The full text of the current version of HB3305 can be seen here.

HB 3305 mandates non-petroleum diesel be the only legal fuel for sale to diesel powered motor vehicles in Oregon.

Star Oilco has customers ask about this proposal and how real it is?  In Oregon the focus on low CO2 fuels in the legislature is so consistent we can expect this to not go away.  Even if HB 3305 does not move this Legislative session, this will not be the last of biofuel mandates.  For this reason Star Oilco has been working to be ahead of the curve with non-petroleum diesel substitutes. Star Oilco has been selling B99 biodiesel since 2002 and renewable diesel since 2015.  If your fleet has an interest in learning more about low CO2 fuels or try these fuels, Star Oilco is ready to serve you with both R99 renewable diesel and B99 biodiesel.

News coverage of Oregon HB 3305 is below

The Center Square’s Oregon, whose coverage of this has been syndicated to many other online news organizations, lead with the headline: Bill in the Oregon Legislature would ban diesel fuel sales by end of decade.

CDL Life had this to say: The bill would begin to ban the sale of “petroleum” diesel by “non-retail dealers” as soon as 2024 in Clackamas, Washington or Multnomah counties and state-wide by 2027.

Landline as well has following the story: Oregon bill would ban petroleum diesel. Later in the article they add this to the background of HB 3305’s origin: Power said in a statement that her goal is to phase out petroleum-based diesel and replace it with renewable diesel. She says she introduced the bill on behalf of Titan Freight, a local trucking company she says has already transitioned to renewable diesel.

KXL covered this local news quoting Oregon State Representative Shelly Boshart-Davis, a legislator who owns a trucking company and actually buys quite a bit of petroleum diesel.

Lars Larson radio interviews Rep. Shelly Boshart-Davis about HB 3305.

KQEN news radio in Douglas County also covered it with the headline: GOP says supermajority declares war on working class.

The Wildcoast Compass covered the story quoting Rep.Vikki Breese-Iverson (R-Prineville): “There is absolutely no way we can implement this legislation in accordance to these timelines without extreme disruption to Oregonians’ daily lives and the obliteration of our economy as we know it,” 

Oregon Public Broadcasting covered HB 3305 a few days after the bill dropped which might be an indication it’s moving forward. From the story: One bill, House Bill 3305, would set a staggered timeline for ending sales of diesel in the state — first in the Portland area, then throughout Oregon. Its backers hope to spur widespread use of “renewable diesel,” a product with far lower emissions that can be used in any diesel engine. They say the fuel could be an important and near-instant way for the state to cut into greenhouse gas emissions while other technologies emerge.

The Banks Post covered HB 3305 as well with the headline: Diesel fuel under fire in Oregon legislature.

What HB 3305 means in the real world?

HB 3305 means the petroleum diesel used by any commercial vehicles operated on Oregon’s highways will be replaced with biofuels.

Biofuels will replace on-road petroleum diesel at all Oregon:

  • Retail gas stations
  • Trucks stops
  • Commercial cardlocks (Pacific Pride and CFN)
  • Privately owned bulk tanks
  • Mobile on-site fueling (wet hose fueling), and
  • All other bulk deliveries of diesel fuel. Star Oilco wanted to provide more background of what this law would mean for Oregon.  We hope this provides in depth information about what the options are for diesel fuels and a whole host of background information.  The news coverage so far fails to really provide this depth and background for those with concerns.  If you have questions, please do not hesitate to ask. Star Oilco seeks to be a neutral and accurate source of information.

Star Oilco sells renewable diesel in bulk and by our mobile on-site fueling service. It is worth mentioning from our first hand experience that users of it become raving fans.  Renewable diesel is a new fuel that many believe out performs petroleum diesel in every way. Many customers who have used it experienced improvements in horse power, fuel economy, and emission regeneration system performance.

Currently renewable diesel is in extreme high demand, limited production, and commands a high premium over petroleum diesel with few sources of supply.  Renewable diesel has some major backers in the trucking industry as well as OEMs.  As the availability of this next generation fuel grows, the number of plants manufacturing it expands, and it’s price comes down, this type of law may make far more sense.

If petroleum diesel is no longer legal for sale in Oregon, what does that mean diesel vehicles will use?

There are two immediately available diesel rated biofuels that can replace petroleum diesel.  These are two very different fuels. Renewable Diesel and Biodiesel have differences in their properties.  So please don’t confuse biodiesel and renewable diesel as the same fuels.

Biodiesel and Renewable Diesel are very different fuels.

Biodiesel is a proven and longtime available fuel in Oregon.   Biodiesel is not actually a hydrocarbon diesel though, it is a diesel like biofuel made from vegetable oil usually sold in a 5% to 20% blend with petroleum diesel. It is not recommended to run pure biodiesel in late model diesel engines if they have a particulate trap.  This differs from Renewable Diesel which is a next generation synthetic hydrocarbon diesel made from various feedstocks including vegetable oil.  It is actually diesel, it can be used as a pure drop in fuel without any blending with petroleum diesel.

What are non-petroleum diesel fuels?

Oregon HB 3305

Biodiesel or B99 (99% Biodiesel + 1% Petroleum Diesel)

Renewable Diesel or R99 (99% Renewable Diesel + 1% Petroleum Diesel)

Blends of Biodiesel and Renewable Diesel (branded REG UltraClean Diesel)

HB3305 allows for biofuels in replacement for diesel.  We assume that change would be from a current Oregon fuel mandates of B5 or R5 biofuel diesel blend to a B99 or R99 mandated fuel.  Oregon’s biofuel content law can be read at ORS 646.922 and we can assume this would change that to a 99% mandate. Why 99% instead of 100%, that is a good question relating to Federal regulation of the US diesel and gasoline markets.

 

Why does this require a 99% blend (B99/R99) instead of 100% biofuel?

The reason biodiesel and renewable diesel are sold at a 99% blend is because of Federal rules associated with how petroleum companies must handle these fuels.  For this fuel to be used under the US EPA’s Renewable Fuel Standard program biodiesel and renewable diesel must be blended at a minimum 1%.  When fuel is blended at 1% with diesel, the EPA enables it to generate a “Renewable Identification Number” or “RIN” which is regulated to ensure a minimum amount of biofuels is used in the stream of commerce for fuel in the United States.  This Federal program is separate and unrelated to any program in Oregon, though the law recognizes and seeks to align with the framework created by the EPA.

What are the fuels HB 3305 allows to be used by diesel motor vehicles?

The two fuels immediately available if are B99 Biodiesel and R99 Renewable Diesel.

Both of these fuels exist today but have their own drawbacks.  In a nutshell, B99 is not a drop in substitute for petroleum diesel.  It is recommended to be blended at 20% with petroleum diesel (NOTE: B99 biodiesel can be used in modern diesel with an up-fit kit provided by Optimus Technologies).  On the upside, biodiesel is plentiful and competitive with petroleum diesel in cost.  If HB 3305 passed though this plentiful fuel wouldn’t be a ready substitute beyond a 20% blend with renewable diesel or with mechanical changes to existing trucks.  Contrast this with  R99 renewable diesel as a drop in ready to go substitute for petroleum diesel.  It is ready to use without blending, but has the downside of being in short supply and at a cost premium above petroleum diesel.

If Oregon’s over 2,000,000 gallons of diesel usage a day (or 750+ million gallons a year) was mandated to renewable diesel no doubt that premium would probably exceed $2 a gallon over petroleum diesel given R99’s lack of ready additional supply.  This $5 a gallon presumes that Oregon would have to pay more for the existing renewable diesel supply finding it’s way to California with several dollars a gallon of value paid for it’s lower CO2 baseline value.  California has a Clean Fuel Standard and a CO2 Cap and Trade program which provide a monetary value for renewable diesel’s lower CO2 numbers.  Oregon has a Clean Fuel Program as well, but it’s program does not pay as much for low CO2 fuels as California, making low CO2 fuels such as renewable diesel more expensive in Oregon.

B99 Biodiesel in depth.

Blends of biodiesel below 20% are extremely common in Oregon.  All fuel must contain at least 5% biodiesel content and many retail outlets, cardlocks, and major truck stops commonly sell a 10% to 20% blend of biodiesel around the state.

Biodiesel is a diesel like fuel manufactured by a chemical reaction called transesterfication, typically from vegetable oil or recycled cooking oil.  It is made by a relatively simple process and biodiesel has been a proven fuel in use in Oregon for nearly twenty years.  Star Oilco started handling and selling biodiesel in 2002.  Prior to 2007, B99 was commonly used by many commercial fleets due to it’s huge reductions in tail pipe emissions.  Vehicles manufactured after 2007, are clean diesels.  The US EPA required new clean diesel emissions systems which are impressive in their ability to make modern diesel engines extremely clean, but they can only handle biodiesel blends below B20 or 20% biodiesel unless an upgraded system is added.

Today B99 is a possible fuel for a modern clean diesel fleet with an upgrade to existing vehicle fuel supply system.  Optimus Technologies has an approved technology to enable a modern diesel aftertreatment system to operate without problems on B99.   Star Oilco has purchased five of these systems and is currently fielding them in the Pacific NW.  We expect these systems to be mainstream in coming years, but just like Renewable Diesel the technology is newly available and scaling up.

For more information about biodiesel please see our biodiesel FAQ titled Every question Star Oilco has been asked about biodiesel.

If you are interested in using biodiesel in your fleet, you can contact Star Oilco with questions or if you want to start researching we highly recommend starting with this US Department of Energy handbook titled Biodiesel Use and Handling.

 

R99 Renewable Diesel in depth.

Renewable Diesel is a next generation biofuel made from fats, oils, and greases. It is not an alternative diesel, renewable diesel is a petroleum free hydrocarbon diesel fuel. It is diesel! Renewable diesel not only less than half the CO2 of diesel refined from petroleum fuel, but it is cleaner burning and has shown evidence of reducing the cost of maintenance in fleets using it. Renewable diesel is a profound technology which has the potential to use the lowest grade trap greases, sewer materials, rendering wastes, municipal garbage, and a host of other refuse products making them into this high performance, sustainable, low CO2 diesel.

There are two categories of technology that renewable diesel is made from.  Hydrogenation and Fischer Tropsch process.

Renewable Diesel from Hydrogenation or Hydrotreating

Hydrogenation derived renewable diesel is very similar in manufacture to modern petroleum diesel in that the molecules of a the feedstock is cracked and reformed in the presence of a catalyst to form a very specific series of hydrocarbon molecules.  These being diesel and propane range fuels. The feedstocks used by renewable diesel plants are vegetable oils and animal fats.

The hydrotreating plants providing renewable diesel to Oregon currently are Neste from a plant in Indonesia, Diamond Green (in a joint venture with Valero), Sinclair, and Renewable Energy Group. All of these plants are over subscribed and 100% of their production is being taken at a premium primarily by the California low CO2 fuels market.   There are several new renewable diesel plants under way though.  Holly Frontier, Marathon, CVR Energy, and Phillips 66 are converting existing petroleum refineries into renewable diesel plants.  This process costs billions of dollars, will take years to complete, and also will be likely destined for California’s low CO2 fuel market with smaller markets like Oregon being an afterthought.

Renewable Diesel from Fischer Tropsch process.

Currently there are a number of smaller demonstration facilities making renewable diesel from wood waste and other feedstocks.  The largest proposed project currently on the books is Illinois Clean Fuels which will be collocated with major CO2 capture facility making their product negative CO2.  Fischer Tropsch renewable diesel is expected to be the future of refining given it’s flexibility of feedstock.  It’s process enables the use of municipal garbage, agricultural waste, woody biomass, and other low value plentiful materials as feedstock.  Given that the United States is called by some the “Saudi Arabia of garbage” we have plenty of supply waiting for a higher and better use as low CO2 transportation fuel.  Illinois Clean Fuels has a great explanation of how Fischer Tropsch makes renewable diesel and jet fuels.

Where can you get Renewable Diesel in Oregon?

Star Oilco currently is selling R99 Renewable Diesel for commercial use.  We can deliver to fleets seeking it in bulk or mobile onsite delivery (wet hose R99 diesel service began in the Spring of 2021).  Call Star Oilco if you have an interest in Renewable Diesel for your fleet 503-283-1256.

If you have questions about renewable diesel, Star Oilco wants to provide answers.  Feel free to reach out if we do not have the answer we will research it.

What Is Portland’s Renewable Fuel Standard?

Diesel Fuel Is Changing In Portland With The Renewable Fuel Standard (RFS)

Portland Old Town sign representing the city’s commitment to renewable fuel standards

Figuring out what this means for you or your business can be challenging. We have shared many questions that we have been asked already, to help provide more clarity on what this Renewable Fuel Standard (RFS) means for Wholesale Purchaser-Consumers. If your question isn’t listed below, please reach out to Star Oilco so we can make sure your questions are answered!

Choose Star Oilco As Your Preferred Fuel Delivery Company

The Renewable Fuel Standard (RFS) is Portland City Council’s response to the City’s 2022-2025 Climate Emergency Workplan,  which lists the City’s priority actions over the next three years.

On Dec. 7, 2022, City Council unanimously adopted amendments to the Renewable Fuel Standard, Portland City Code Chapter 16.60, which reduces dependence on nonrenewable fossil fuels, by increasing the required percentage of renewable fuels blended with petroleum diesel sold in the city of Portland.

This policy increases low-carbon biofuel blends, moving Portland’s diesel fuel mix to 99% renewable by 2030. This policy includes a carbon intensity standard to shift to fuels that are lower carbon across their entire lifecycle.

Portlands Renewable Fuel Standard Requirements

 July 1, 2024, Portland required that all diesel fuel sold contain a minimum 15% blend of biodiesel or renewable diesel. This percentage will increase steadily over the next few years, reaching a minimum 99% renewable fuel requirement by July 1, 2030.

There are no reporting requirements for retailers to comply with this mandate. Instead, the city enforces compliance through random on-site inspections and by requiring retailers to maintain records of the biofuel content of the diesel they sell.

  • The policy speaks to “Covered Entities
  • Diesel Fuel Transaction within the City of Portland Oregon
  • Fuel distributors, resellers, retailers, nonretail dealers, terminals, importers and wholesale purchaser-consumers are directly regulated by PCC Chapter 16.60 and referred to as “covered entities.”
  • Wholesale Purchaser-Consumers​: also know as WPCs are directly regulated by PCC Chapter 16.60 and referred to as “covered entities.”

Wholesale purchaser-consumer (WPC) is a category of entities that own or utilize diesel vehicle fleets and purchase fuel in bulk for delivery into a storage tank at their facility or directly into a vehicles fuel tank. WPCs are required to register with the RFS program.

A fuel distributor or common carrier delivers on road diesel to your facilities on-site tank such as: 

  • Bulk Tank
  • Aboveground Storage Tank (AST)
  • Underground Storage Tank (UST)

A fuel distributor delivers on road diesel directly into your vehicles also known as:

  • On-Site Fleet Fueling
  • Wet Hose Fueling

Yes, these rules apply to fuel for on-road motor vehicles. Fuels used for the following purposes are not covered by these rules

  1. Railroad locomotives, watercraft, aircraft, and emergency equipment
  2. Dyed diesel for off-road vehicles
  3. Dyed diesel for furnaces, boilers, generators
  4. Propane and liquefied natural gas for vehicles

Wholesale Purchaser-Consumers are required to meet three primary components of the RFS:

  1. Biofuel Minimum Content Requirements,
  2. Carbon Intensity standard,
  3. Selecting a compliance option, and
  4. Record keeping.

Biofuel Minimum Content Requirements for Wholesale Purchaser-Consumers

  • WPCs in the City of Portland are required to meet the minimum biofuel content requirements for all fuel they purchase for their vehicle fleet. Beginning July 1, 2024, all diesel purchased must include 15% biofuel content, from either renewable diesel or biodiesel. This requirement increases to 50% on July 1, 2026, and 99% on July 1, 2030.
  • The biofuel content requirements will be enforced through random inspections of fleet facilities to see that they (1) have a contract in place with fuel suppliers that specifies that fuel meets the minimum blend requirements, or (2) verification of actual products purchased through testing or review of product transfer documents.
  • All WPCs also need to be aware of the Carbon Intensity Standard in PCC Chapter 16.60.
  • All biodiesel and renewable diesel sold in the City of Portland must have a carbon intensity equal to or less than 40g CO2e/MJ as certified by DEQ’s Clean Fuels Program, Approved Carbon Intensity Values.
  • Carbon intensity requirements apply to biofuel blendstock, not the final blended products, which may contain a portion of petroleum-based diesel fuel at a higher carbon intensity.

Selecting a compliance option for Wholesale Purchaser-Consumers

  • WPCs will need to select a compliance option by the start of the compliance period, July 1, 2024.
  • Portland Bureau of Planning & Sustainability (BPS) will provide notification about selecting compliance options by May 31, 2024.
  • To receive notification, covered entities must be registered with the RFS Program

*Compliance option selection may be changed at any time during the compliance period after consulting with BPS. If a covered entity decides to change the compliance option during the compliance period, they are responsible for compliance under the new option for the full compliance period.

Record Keeping Requirements for Wholesale Purchaser-Consumers

Portland City Code (PCC) Chapter 16.60 and administrative rules requires that an invoice, bill of lading, shipping paper, or other documentation, referred to as “Product Transfer Documents” (PTD) must accompany each fuel delivery in the city of Portland. The administrative rules specify that:

  1. PTDs must include the type of renewable fuel, including biodiesel, renewable diesel, ethanol, or any blends of these fuels, and declare the volume percent of such renewable fuel.
  2. PTDs must comply with OAR 603-027-0430 (1) (a) which includes identifying the quantity, the name of the product, the name and address of the seller and buyer, and the date and time of the sale.
  3. WPCs using the Product Transfer Document compliance pathway must also ensure that fuel pathway codes issued by Oregon Clean Fuels Program are also included on a PTD associated with each delivery received by the WPC or have a contract with a fuel supplier specifying the carbon intensity requirements of PCC Chapter 16.60.

B99 Biodiesel for Fleets & Heavy Equipment 150 150 Star Oilco

B99 Biodiesel for Fleets & Heavy Equipment

Using B99 Biodiesel in a Tier 4 Heavy Duty Diesel

B99 Biodiesel reduces CO2 footprint of a 105,500 GVW truck and trailer by more than half at a lower cost than petroleum diesel.

What is B99 Biodiesel?

B99 Biodiesel is as pure of blend of Biodiesel you can get in the United States and still participate in the incentives associated with this alternative fuel.  B99 is the product received by petroleum refiners, terminals, and truck stops to blend with petroleum diesel.  Biodiesel is a renewable, clean-burning diesel replacement.  B99 Biodiesel is a common blendstock with petroleum diesel (being 99% biodiesel).  It can be presumed that nearly every major truck stop throughout the US is consistently using either a blend of 5%, 10% or 20% of biodiesel   The reason for this is both due to its price advantage against petroleum currently as well as Federal/State laws requiring it’s use.

Why Higher Blends of Biodiesel Matter?

Biodiesel is a low CO2, net energy positive fuel.  Depending on the feedstock Biodiesel is made from a CO2 reduction of 30% to 80%+ can be expected compared to petroleum diesel.  As the West Coast (Oregon, Washington and California) ramps up CO2 regulations that charge an additional cost for carbon emissions associated with petroleum diesel the financial case for Biodiesel becomes obvious.  Early adopters will see direct financial benefit.

Star Oilco has fielded the Optimus Technologies system on our 105,500 GVW truck and trailers.  Star Oilco began with a single Freighliner truck and trailer operating a Cummins ISX as a trial.  This truck’s typical route was approximately 305 miles round trip from Portland, Oregon to Grays Harbor, Washington.  This run is from Star Oilco in Portland, Oregon to the Grays Harbor REG Biodiesel plant and back to the Portland terminals for delivery of this product.    Over the last year and a half this truck has performed amazingly well, the only maintenance concern is swapping the fuel filters more regularly with every oil change.  Mileage and power difference are negligible as noticed by drivers or our Elog system.  On a few occasions a loss of power was experienced requiring an in between service fuel filter swap.

This field trial of the Optimus Technologies system Star Oilco has regularly saved between $15 and $75 a day when running this dedicated route, depending on the cost of B99 Biodiesel versus petroleum ultra low sulfur diesel.  Consistently the price of B99 Biodiesel has been below petroleum diesel in the Portland, Oregon market. This has been due to a combination (or is effected by) RIN values, a Blender’s Tax Credit on biodiesel, and Oregon’s Clean Fuels Program which also prices the CO2 reduction value of B99 Biodiesel.   We see this trend continuing as an assumed market reality for biodiesel.

What is the business case for our deploying B99 Biodiesel Optimus Tech upfit kits?

The systems increase the intelligence of our late model trucks with their very complicated Tier 3 and Tier 4 emissions systems.   The Optimus Kit enables two saddle tanks to operate with the duty cycle of the truck. One tank (which we will be running B5 ULSD or R99 through) is dedicated to fuel the particulate trap and SCR systems.  These systems have extremely tight tolerances and tend to choke on higher blends of biodiesel.  By dedicating a tank with a smart controlling system we reduce the maintenance and concern with these after treatment systems hopefully extending the maintenance cycle on these traps by years while reducing inconvenient efficiency killing regens.

The Optimus Kit also enables a modern diesel engine to run B99 Biodiesel.  It does this by controlling the temperature of the fuel in it’s dedicated saddle tank and routing B99 to the engine when the RPMs and operating temperatures are best for this fuel. Upon start up and shut down the Optimus Technology kit will flush the engine, fuel rail, and injectors with the petroleum/R99 tank ensuring easy start up and no cold weather effects.  The B99 saddle tank is temperature controlled as well to enable performance in extreme weather.  When operating under load the Optimus Kit will move to B99 as the fuel into the engine.  As B99 Biodiesel has a substantial reduction of emissions, particulate, and other compounds when combusted; this further reduces the impact of miles on a truck to the particulate trap and it’s service needs.

Beyond this maintenance experience, the performance and function of the system has been indistinguishable to our other trucks running the same route.

Biodiesel Mandates in the Pacific Northwest

Oregon and Washington have passed legislation which puts a price on the CO2 emissions associated with petroleum diesel.   These laws mean that petroleum fuel costs more than biofuels with a low CO2 footprint.  These laws are also added on top of other mandates and incentives for biofuels.  Biodiesel blends between 5% and 20% are common on the west coast at every gas station, cardlock, and truckstop.

How Can I Utilize B99 or B100 in My Own Fleet? 

Star Oilco uses The Vector System developed by Pittsburgh-based Optimus Technologies. The Vector System is the only EPA-compliant biodiesel engine system and upgrades any medium or heavy-duty engine to operate on 100% biodiesel. It can be installed in as little as 12 hours. Learn more about The Vector System by contacting Optimus Technologies here directly or by reaching out to Star Oilco locally.

The Future of Diesel Fuel: Trends & Outlook

Diesel Fuel In Oregon and Washington

Star Oilco has been getting questions on the changes of diesel in Portland, Oregon.  If you have not noticed, many diesel pumps at retail gas stations and cardlock have seen changing stickers on the face of the fuel pumps.  As of July 1st, 2024 the City of Portland requires a minimum 15% biofuel content of all diesel sold.  This policy is called the Portland Renewable Fuel Standard.

This has caused quite a few changes in what fuel pumps have for fuel.  Diesel fuel buyers are noticing the bright yellow color of B20 biodiesel, the water clear color of Renewable Diesel or a a mix of several fuels tinting the color of their diesel.  This trend is bigger than just Portland.

Today on the west coast there are a variety of product label stickers you will see on diesel pumps.  These show the variety of diesel fuel specifications that are being sold to diesel vehicles today. Blends of petroleum ultra low sulfur diesel, R99 (99%) renewable diesel, and B99 (99%) Biodiesel are combined to meet the market needs of the diesel we all buy.

This change is because of a combination of pure market forces, government rules and local decisions by fuel haulers.  Today’s diesel not only has a commodity market for the fuel it also has a market for CO2 credit value and a cap of total petroleum diesel fuel that can be sold into a west coast state with a “Cap and Investprogram requiring blends of low CO2 biofuels, the liquid fuels sold for vehicles.

Add on top of these market forces, advances in technology used to make the liquid diesel fuel.  The diesel arriving at truck stops, gas stations, cardlock or out of a hose from a bulk truck has been changing and it’s often in good ways.  Knowing how can be helpful in navigating why diesel may cost one price or another and may have a need or maintenance that another fuel does not.

THE RISE OF RENEWABLE DIESEL

Renewable diesel is a synthetic diesel fuel made from the same feedstock as biodiesel, but the finished product is hydrocarbon diesel.  Though it is a biofuel, it is also diesel. For fuel regulation they refer to it (as well as biodiesel) as “Biomass Based Diesel” for labeling at the fuel pump.

There have been billions of plant capacity brought online for renewable diesel.  During the COVID collapse of fuel prices a number of petroleum refineries shut down, then upgraded their technology to make hydrocarbon diesel fuels out of the very biobased fats, oils, and greases biodiesel is made from.  These refineries use hydrotreating technology just like they do with a crude petroleum to make an actual hydrocarbon diesel molecule.   With this technology adoption to make diesel and jet fuels from vegetable oils and animal fats billions of gallons of low CO2 diesel fuels are coming on the market and governments are requiring it’s use, such as Portland’s Renewable Fuel Standard.

Renewable Diesel Consumption it the US Source: Alternative Fuels Data Center

THE AVAILABILITY OF BIODIESEL

The US makes billions of gallons of biodiesel.  A fuel that’s quality and performance continues to improve.  If you are not a fan of biodiesel in your fuel thinking strategically about the fuel will likely benefit your fleet operation.  The big concern with diesel fuel in a ultra low sulfur world is water and dirt suspended in the fuel affecting the performance of diesel emission systems.  With clean and drier quality specifications of B99 blend stocks today versus a decade ago the use of this fuel has grown substantially especially in the truck stop market.

When crude petroleum prices are high and therefore refined diesel prices are equally as high biodiesel is often an extremely competitive fuel.  If a large seller of diesel (including petroleum refiners) can pick up pennies per gallons on millions of gallons sold they will do so.  Therefore Biodiesel is often seen in diesel in small blends even if you do not see a label on retail pump.  For blends above 5% a label is required for retail fuel sales. RTHWEST?

Biodiesel Blend Percentage label for retail diesel dispenser

Above are a variety of labels used to denote what fuel blend is coming out of a retail diesel dispenser. Feel free to call Star Oilco at 503-283-1256 if this confuses you and you want it explained.  We would be glad to do so.

These labels can be found together often at one pump.  All state and Federal standards require ultra low sulfur diesel for any on-road diesel sale.  The Federal standards also adopted by the states require a disclosure at the fuel pump if a blend is above 5% biodiesel.  The max allowable blend of biodiesel for diesel truck manufactures is a 20% blend.  If a truck dealership says that you cannot blend biodiesel up to 20% they need to take that up with the Federal Government because they need to support it.  This is why the label shows a blend may contain between 5% and 20% biodiesel content.

Renewable diesel is a hydrocarbon diesel. 

 

It is diesel meeting the ASTM D975 specification for diesel. 

Retailers selling blends of R99 in their fuel do not need to label it given this.  They still do label it given the benefits of the fuel’s performance and that customers are seeking that fuel.

Many retail places will have stacked labels showing they may be blending 5% to 20% biodiesel as well as may be adding R99 Renewable Diesel to the fuel as market conditions dictate it is the more cost competitive fuel.  When seeing a label like this it can usually be assumed they are blending a R80 (80% Renewable Diesel) and a B20 (20% Biodiesel) blend of fuel.  This blend is actually believed by some to be a higher performing fuel seeing better performance that a R99 or B20 fossil fuel blend.

Fossil fuel diesels are being replaced or blended with biomass based diesels.  Be it Renewable Diesel or Biodiesel.  These blends are driven by more than one industry requirements, government rules, or other market forces. One of these being Portland’s banned on petroleum diesel through the Renewable Fuel Standard (RFS). This is resulting in an increase of low-carbon biofuel blends that will ultimately move to a mix of 99% renewable fuel requirement by 2030.

Renewable Diesel and Biodiesel Blend fuel dispenser label.

The big drivers are industry specification for fuels (both labeling as well as chemical characteristics), state rules on selling these fuels, their quality assurance as well as CO2 content, and of course the market forces.  Market forces being the supply and demand availability of fuel needed to meet customers.  Less fuel available to sell means higher prices for customers.

A decade ago the market for diesel was far simpler. Though you had biofuels and some blend mandates basically you had a diesel specification accepted and the daily price as tracked by a lighted retailers sign, a wholesale market average or spot buying by some customers.   Today this market is far more complicated by government regulation on the west coast.  There are three big programs at state levels impacting this.

State Fuel Rules cause a unique need for one state or another. Whereas twenty years ago if Oregon or Washington fuel was selling for more than the Gulf Coast you might see brokers bring fuel into the region then driving down high prices.  With the creation of various complex and unique rules on diesel, imports of fuel to these low CO2 fuel states has dropped.  The amount of people moving product into west coast states has dropped.  The big rules causing this are the Cap and Invest programs of the West Coast states, the Low CO2 Fuel Standards of the states, and the fuel blend mandates of various jurisdictions of these states. For instance California now requires all off-road diesels but 99% renewable diesel.  Portland, Oregon also has a CO2 requirement and minimum 15% blend of biomass based diesel on all fuel sold in the state.

WHAT ARE THE DIESEL FUELS AND THEIR SPECIFICATIONS

Petroleum Diesel:
ASTM D975 Specification.

The ASTM D975 is a series of tests used to maintain consistent industry standard product performance for diesel fuel.  It includes among several tests cloud point, cold filter plug point (CFPP), several masurements of diesel fuel operability performance, intrained water content, sediment, carbon residue, ash, distillation, viscosity, sulfur, copper corrosion, cetane number, cetane index, aromaticity, and conductivity.

Renewable Diesel:
ASTM D975 Specification.

Renewable Diesel is following the same series of tests as petroleum refined diesel fuels.  It is the same ASTM D975 specification. Though Renewable Diesel has some different properties that exceed the ASTM specification of diesel.  Renewable Diesel is highly prized as a fuel because it typically is a cleaner and drier diesel fuel than petroleum diesel. This being seen by the tests on sediment and water content in a parts per million level.  Renewable Diesel content in diesel fuel can also be tested for looking for a C14 molecule (the chain typically created in a Hydrotreated Diesel process from fats, oils and greases.

Biodiesel (Methyl Esther):
ASTM D6751 Specification.

The ASTM for Biodiesel tests a mono-alkyl esters of long chain fatty acids derived from vegetable oils and animal fats. The testing for quality assurance covers an analysis for flash point, methanol, water and sediment, kinematic viscosity, sulfated ash, oxidation stability, sulfur, copper strip corrosion, cetane number, cloud point, acid number, carbon residue, total and free glycerin, phosphorus, reduce pressure distillation temperature, atmospheric equivalent temperature, combined calcium and magnesium, and combined sodium and magnesium.

For more on Biodiesel Use and Handling the National Renewable Energy Laboratory has a great book on the subject.

THE HISTORY OF DIESEL FUEL SPECIFICATIONS IN THE UNITED STATES

In the 1990’s the US EPA passed rules that demanded a phase out of sulfur in diesel fuel.  The presence of sulfur was very good for the fuel’s storage stability as well as fuel lubricity, but was horrible for air quality.   Additionally the big smog contributor was NOx (nitrous oxide) which was one of the EPA’s reason’s for pulling sulfur out of diesel.  For the EPA to get engine manufacturers to treat the NOx emissions at the tailpipe they needed all the sulfur gone (ultra low sulfur diesel) for modern diesel emission systems to be able to eliminate NOx as well as a host of other pollutants including particulates.

The story of changing diesel fuel standards in the US under the EPA is one of removing sulfur from our diesel fuel.  In 1996 the fuel refiners and sellers of diesel had to move the sulfur content of the fuel sold for on-road purposes to below a 500 parts per million standard. Commonly referred to as Low Sulfur Diesel fuel.   In 2006 the standard moved to a maximum of 15 parts per million of sulfur for all on road fuels.

In 2006 while the sulfur content of fuel was dropping the City of Portland released the first mandated blend of biodiesel content.  This being a 5% biodiesel blend.  The next year, the State of Oregon followed with its own Renewable Fuel Standard requiring this throughout the state.  This began the expectation of biodiesel in most diesel fuel in the Portland, Oregon area.  Washington also passed a similar policy for blending biodiesel but the enforcement and need for the fuel is less specific at Washington fuel pumps.

Every Question About Off-Road Diesel

Got questions about red dyed diesel? We have answers!

If you don’t find the answer you’re looking for related to red dyed diesel (or off-road diesel) reach out to us directly and we’d be happy to help answer your questions.

Red Diesel is off-road diesel, in the United States this fuel is denoted with a red dye. The dye marks this as fuel for off-road equipment and vehicles and as such it doesn’t have road fuel taxes included in the priceThis dye takes a great deal of clear fuel to dilute so it makes it very obvious if an on-road vehicle has been using off-road untaxed fuel. Tax authorities can and do check for vehicles using off-road red diesel in on-road vehicles. They do this by using a black light to spot any residual presence of dye in the fuel as well as at key places in the engine compartment.

On-road diesel is clear or slightly green. Refineries place a green dye into diesel fuel which is obvious if fuel is freshly dispensed into a bottle to observe its color. As fuel ages this dye fades to yellow or darker colors. Part of a visual observation to inspect diesel fuel quality is to check the fuel for a “bright” appearance with the slight green dye being a giveaway that the diesel is fresh and in good condition.

Nearly all diesel has dye in it. Typically when talking about dyed diesel, we’re referring to a red dye added to off-road diesel. Off-road diesel is normally used for heating oil, construction fueling, agricultural use, and other off-road equipment not used on the highway system where fuel taxes would be required by law.

comparison chart showing difference between off-road diesel and on-road diesel fuel in Portland OR

Why is diesel dyed?

Diesel is dyed in order to denote if it has paid road tax or not. On-road diesel in the United States usually has a light green tint to it. Off-road diesel has a red dye to denote it has not paid road taxes as required by all states and the Federal government.

What is off-road diesel?

Off-road diesel is diesel fuel dyed red to show it is untaxed and available only for off-road fuel uses such as construction fueling, equipment never used on a public road, agricultural use, heating oil, boiler fuel, and other non-taxed diesel fuel uses under state and Federal fuel tax law. In Oregon, with proper paperwork, some off-road uses can buy on-road fuel with the Oregon state tax exemption.

What is farm diesel?

Farm or diesel for agricultural use is off-road diesel that is not charged on-road fuel taxes. Agricultural use fuel is a tax-exempt use of diesel fuel. If diesel is burned on a farm and can be tracked for such, taxes can be avoided. Farms are allowed to receive clear diesel without road taxes charged on it in Oregon. Often it is dyed red to denote it is tax free. In Oregon, where P.U.C. for trucks over 26,000 GVW pay a weight mile tax instead of a per gallon state road tax, some farms will track their use of clear diesel so they can file for Federal road taxes on off-road usage.

All diesel sold in the United States typically has some dye in it. On-road diesel usually has a slight green tint to it. This is a dye added by either the refiner or terminal provider with the fuel. Off road diesels are dyed red to denote that the fuel is untaxed and is for use in off-road purposes only.

Solvent Red 26 and Solvent Red 164 are the allowed dyes prescribed by the United States Internal Revenue Service for marking diesel as for un-taxed off-road use only.

Off-road diesel is classified as a Class II combustible liquid by the National Fire Code. A flammable fuel is one with a flash point below 100 degrees F. Diesel’s flash point is between 126 and 205 degrees F (typically assumed to be about 160 degrees F)That classifies it as a Class II combustible.

Fuel taxes charged is the big difference between the two fuels. All on-road diesel is clear or greenish in color to denote it is both ultra-low sulfur diesel and the on-road fuel taxes associated with using it to power a highway vehicle have been paid. Dyed fuel means that fuel taxes are not paid and that the fuel can not be used to power a vehicle on a public road.

It depends on the sulfur content of the fuel and the year/engineering of the truck.  If your dyed fuel is ultra low sulfur it is typically the exact fuel as on road diesel with an added injected red dye to denote it is untaxed for off road use only.

Red Dyed fuel can occasionally be low sulfur or high sulfur content.  That sulfur content will create real issues with a  post 2007 pick up or commercial diesel truck with a tier 3 or tier 4 emission system.  Most diesel in the US today including off-road diesel is ultra low sulfur (under 15 ppm sulfur). Low sulfur diesel is over 15 parts per million and can be as high as 500 ppm.  High sulfur diesel is over 500 ppm and can range in the thousands of parts per million.  That sulfur means far more soot and black smoke out of your tail pipe.  If you are “rolling coal” out of a modern diesel that’s bad for the truck as well as violates emissions laws in the US.  Similarly if you are using a 2007 or newer truck it will have very tight tolerances on the fuel injectors which can more easily coke up if running a higher sulfur or even dirtier specification diesel.  It is recommended to use ultra low sulfur fuel in all equipment.

It is illegal because diesel used for on-road use has taxes to pay for those roads. These taxes are charged at a federal, state, and municipal level depending on where you are at.  Off road diesel has a red dye injected into it at the time of loading the fuel delivery truck.  This loading of a fuel truck at a terminal is the point of taxation and tracking for diesel down stream in the economy.  If you see a fuel with a red dye, it is untaxed.  To use this in an on-road vehicle if you get caught can result in huge fines. In Oregon it could be as much as $10,000 a day for use of red dyed diesel in an on road use.  It is not uncommon for scale stops of commercial tanks to flashlight a saddle tank and check for any evidence of dye in fuel at a DOT scale stop.

Is off-road diesel or dyed diesel high sulfur diesel?

Dyed diesel (or off-road diesel) can be high sulfur fuel. High sulfur diesel is defined as diesel fuel with over 500 parts per million of sulfur content.

Is off-road diesel or dyed diesel ultra-low sulfur diesel?

Off-road and dyed diesel fuels can be ultra-low sulfur but are not guaranteed to be. There has been a consistent push to reduce sulfur in all fuels in the United States as led by EPA regulation. In recent years, EPA standards require off-road construction and agricultural equipment to have an emissions system that allow ultra-low sulfur to operate without major problems. So today’s off-road diesel being delivered is ultra-low sulfur. If you have a tank with old stored dyed red diesel fuel in it, you can assume it has a higher than ultra-low sulfur content.

What is dyed ULSD fuel?

Dyed ULSD fuel is ultra-low sulfur diesel with a red dye in it to denote that it is for off-road or untaxed purposes only. These purposes are typically for heating oil, construction fuel, agricultural fuel, generator fuel or other off-road uses. The “ULSD” is an acronym for ultra-low sulfur diesel.

Dyed diesel can be either #1 or #2 diesel. Both fuels require a red dye in them to confirm they are untaxed and cannot be used for on road fuels.

Dyed diesel and off-road diesel can be kerosene (which crosses as #1 diesel fuel), but not necessarily. Do not assume a dyed fuel is kerosene, which is a rarer fuel. Kerosene is different than #1 diesel for one characteristic: its confirmed ability to be absorbed and taken up by a wick. All kerosene is #1 dieselNot all #1 diesel fuels are kerosene. The same goes for dyed diesels and off-road fuels. All dyed kerosene is dyed and off-road diesel. Not all dyed fuel is kerosene.

Yes, dyed diesel and off-road diesel are stove oil. Typically a #1 stove oil or #2 stove oil, similar to diesel. Historically stove oils had a slightly different set of specification concerns which is why they were called “stove oils” versus diesel. When petroleum refineries distilled crude oils to get diesel range fuels, it was less exact than it is today with hydrocracking technology. Today with both oil refinery technologies and the EPA emission regulations, the number of distillate range fuel specifications is far more consolidated in order to ensure compliance with EPA and state rules. If your heating appliance is demanding stove oil, it typically needs a #1 stove oil or #1 kerosene product. This product is expected to produce less soot and therefore to work better in a pot stove type of application. The most modern stove oil appliance in the U.S. are Monitor and Toyostove thermostatically controlled direct vent heaters.

Depends on the year of your truck, and we assume you mean red dyed diesel fuelFirst, using dyed diesel, off road diesel, or heating oil in an on-road vehicle is against the lawIf you are caught in Oregon the fine can be as big as $10,000 and the State of Oregon does aggressively pursue this type of tax avoidanceBeyond the legal use of off-road fuelTypically on the west coast dyed diesel is ultra low sulfur diesel. Which means it will not cause maintenance issues if burned in your engine.  Dependent on the age of the dyed fuel, or if it is actually a heating oil, it might be high sulfur or low sulfur fuel. If you use that in a post 2007 engine with a particulate trap it will have serious maintenance issues if you use that fuel.

Yes, dyed diesel and off-road diesel are acceptably used as heating oil. Dyed diesel and off-road diesel these days are typically ultra-low sulfur diesel. Heating oil can be low sulfur or high sulfur in content under EPA and most state laws. So heating oil sometimes cannot be dyed diesel (when used for off-road equipment or agricultural use) but dyed/off-road diesel can always be used for heating oil and conform to the necessary specification required by heating oil furnaces.

Yes! But in today’s ultra-low sulfur market, most off-road diesel is below 15 parts per million. If your equipment requires ultra-low sulfur diesel, it is a good practice to confirm that is what fuel you are getting. Some low sulfur diesel (under 500 parts per million sulfur fuel) and high sulfur diesel (over 500 parts per million sulfur) is still in the marketplace used by heating oil, boiler systems, locomotive, and marine applications.

Off-road diesel gels at cold temperatures. At colder temperatures, wax crystals begin to form and fall out of the diesel, clogging filters and gelling up the fuel. Also, the water and naturally held-in diesel will ice up and obstruct filters. This phenomenon is called diesel gelling.

All diesel fuels will gel if it gets cold enough. Both a formation of wax crystals and ice forming in your fuel will obstruct filters and take your equipment down. Rule of thumb: with no treatment your diesel fuel should operate without any issues above 20 degrees Fahrenheit. Below 20 degrees Fahrenheit, you will want to ensure your vendor is treating the fuel for winter use to ensure it will operate down to -20 degrees FahrenheitIf you are facing temperatures below that, you will want to confirm with your vendor that they are testing that fuel to operate below -20 degrees Fahrenheit.

Why does the government require diesel be dyed red?

From a informational pamphlet from the US IRS on untaxed fuel: 

“The federal government requires dyeing of untaxed diesel fuel and kerosene for two reasons. To help reduce tax evasion by identifying fuel on which excise taxes have not been paid, and to help reduce air pollution by identifying fuel not suitable for use in highway vehicles.”

Does off-road diesel go bad?

Off-road and dyed diesel do age and can go bad. All diesel fuels adhering to ASTM specification should be safe for storage up to a year without additional treatment and testing. If you are storing diesel for long term use, it is a good best practice to treat the fuel with a biocide and oxidative stabilizer to ensure that the fuel stays within specification and nothing will begin to grow in your fuel tank. The biggest enemy of long term diesel storage is water and dirt entering the fuel through a tank vent. As temperatures change a tank will breath pulling in air and moisture from outside. Ensuring there is no water in the tank and that outside contaminants can’t get into a tank are how keep your fuel within specification.

Untreated, you can assume that diesel fuel is good for a year. If treated with a biocide to prevent biological growth from growing in the tank, you can expect diesel to be good for two to three years. After two to three years, diesel begins to show age as it loses its brightness when sampled. After three years you will want to sample and test the fuel to ensure it is within specification for reliable use.

Fuel taxes vary by state and sometimes even local municipality. With off-road diesel, usually the only taxes to consider are sales taxes on the fuel. In Oregon there are no taxes on dyed off-road fuel. In Washington state there are sales taxes for dyed-diesel charged on top of the sale price of the fuel. (NOTE: If you use clear diesel in Washington state there is no sales tax as the road tax is being charged.)  If you are curious for a more in depth answer Star Oilco has a full explanation of Oregon Diesel Taxes (a unique system in the United States for local fuel tax collection of trucks over 26,000 GVW).

Yes. If you are consuming dyed diesel and are not paying for the on-road fuel taxes in Washington state, the sales tax is charged. If you use clear fuel with road taxes attached to the fuel, the sales tax is not charged. For more on Washington fuel taxes see the Washington Department of Revenue. 

Your petroleum distributor has some small taxes (under $.01) attached to the fuel they buy at the wholesale terminal level. Those taxes being the U.S. EPA Superfund cleanup and the “LUST” or Leaking Underground Storage Tank cleanup fund. Beyond that, there are no taxes (Federal, state or local municipality) on fuel used for off-road diesel in Oregon state.

In Oregon you can buy clear fuel exempt of Oregon’s state road taxes. The qualifications for using clear diesel Oregon State tax exempt are the following: 

vehicles issued a valid ODOT Motor Carrier permit or pass (weight receipt) 

vehicles issued a valid Use Fuel User emblem by the ODOT Fuels Tax Group 

vehicles registered to a US government agency, Oregon state agency, Oregon county or city, and displays a valid Oregon “E” plate 

vehicles, or farm tractors/equipment only incidentally operated on the highway as defined in ORS 319.520 

vehicles or equipment that are unlicensed and/or used exclusively on privately owned property 

What happens if I use dyed diesel in an on-road vehicle?

If you get caught in Oregon, a $10,000 a day fine can be levied. We have seen fuel tax cheats get caught repeatedly so be aware Oregon is on the look out for any amount of dye in the saddle tank of an on-road vehicle. If the fuel you use is low sulfur or high sulfur fuel and your vehicle has a particulate trap, you will have maintenance issues with the emission system of your vehicle.

Only if that pickup is dedicated to an off-road use. If you plan to ever use that truck on a public road (even to cross a street), and dyed fuel is found in that vehicle, fines up to $10,000 per occurrence can (and are) levied by state regulators. If you have a closed facility or large farm and are not registering the vehicle for on-road use (so the pickup must not leave the site), you can use off-road diesel as the vehicle’s fuel. If you have license plates and it’s permitted for on-road use, any regulator spotting dyed fuel in that truck will presume it is an on-road pickup.

Typically when checking for illegal use of dyed fuel, regulators will sample from the tank or spin the fuel filter and observe for obvious dyed fuel. If the fuel is clear (or even slightly pink) and they suspect dyed fuel was used in the vehicle, they can apply a special black light that will glow an obvious color denoting dyed fuel had been in contact with the vehicle. They will shine that light on the filter, fuel tanks, and various parts in the engine compartment that would have come into contact with the fuel. If those areas denote even a mild trace of the red-dye used in off-road diesel, they will cite the vehicle operator. There are kits sold online for filtering dye out of fuel to remove the colorThose kits will not remove enough dye to avoid detection by these lights.

Off road diesel is dyed red to show that the on-road fuel taxes are not paid or that it is a tax-free fuelThe Federal Government and State Government’s have fuel taxes for on-road fuel usage to help pay for the roads we all drive onIf you are using diesel for a non-road equipment, machinery, or heating/boiler applications the fuel taxes are exempt and the fuel is dyed to ensure it’s tax free status is immediately seenRegulators in a road side or site level inspection can also shine a black light on specific places in a vehicles system to denote if dyed fuel is being used in violation of the law as well.

In the Pacific Northwest at the current moment? Usually nothing. Heating oil is dyed diesel. Most petroleum distributors are selling the mainstream dyed diesel specification for use as heating oil in order to lower the overall cost of the fuel. There are different ASTM specifications for heating oil and dyed diesel dependent on the state you buy it in. Heating oil’s specification has wider tolerances than diesel specifications as furnaces and boilers can handle dirtier, lower quality fuels than off-road equipment with a particulate trap. Heating oil is always a diesel fuel, but sometimes dyed diesel for off-road equipment has a different specification than heating oil. For example, in Oregon a 5% biodiesel or 5% renewable diesel mandate exists for any dyed diesel fuel used in off-road equipment. This biofuel mandate exempts heating oil and boilers. So heating oil can be biodiesel free but off-road diesel for equipment cannot.

Star Oilco truck refueling off-road diesel at a job site in Portland OR

Can refrigerated trailers or “reefers” use dyed diesel even if they are attached to a truck moving it on the highway?

Yes, refrigerated trailers are off-road equipment. The diesel fueled refrigeration trailer is off-road equipment as its engine is not powering something actually driving down the road. These trailers can use any ultra-low sulfur diesel fuel (dyed or clear). If using on-road clear fuel in a refrigerated trailer, if you track and keep proof of the on-road fuel being used in the off-road piece of equipment, you can file for those fuel taxes back. Proof is required though so consult with your CPA or accountant.

The first step is to set up an account with Star Oilco. It’s easy to pay through a simple credit application or by placing a credit card on the account. Oregon and Washington are highly regulated when it comes to fuels such as diesel. We need to account for who is ordering and getting fuel (yes, Oregon even checks sometimes as the DEQ tracks every gallon of diesel moving into the state). Determine if you want a loaner tank onsite or a keep-full service plan. Star Oilco will deliver bulk or wet hose fuel your job site on a regular schedule. We are here to make it as easy as possible for you to focus on your project, not fueling. Let us know what you want: we will keep it simple and make it easy for you.

If you are storing off-road or dyed diesel for longer than six months you will want to make sure it is stabalized. Star Oilco recommends Valvtect Plus Six as the fuel additive you want to useOur recommended fuel additive is a fuel microbiocide with stability additives made for diesel long term storageThis kills and prevents the growth of biological “hum-bugs” in your tankBacteria, yeast, and algae can grow in your fuel tank. Usually in a small amount of water that collects in the bottom of the fuel storage tank (be it the bulk tank you  fuel out of or the saddle tank on your equipment).

There are several ways to do this.  What you will want to do varies based on how much water and what it is in.  If you are dealing with a large bulk fuel tank you want to definitely pump the tank bottom to get the water out.  If you are seeing extreme biological activity (Hum-Bug growing in your tank) you want to do a kill dose treatment on that tank. It might not be a bad idea to also spend a few thousand dollars to have a professional tank cleaning company come in and manually clean the tank prior to adding the kill dose to kill anything growing in your tankIf it’s the tank on your equipment usually the best route is to drain the tank, flush the tank, and also put a kill dose of  a fuel microbiocide to make sure nothing continues to growIf you want to talk to someone feel free to call Star Oilco, you do not need to be our customer for us to walk through some solutions you can do yourself. 

There are a very few rural gas stations that provide this fuel.  Some Pacific Pride or CFN cardlock locations also have pump available for this fuel.  The easiest way to acquire this fuel is through a fuel company.  Star Oilco is one such company that can deliver dyed diesel for it’s customers, or provide cardlock cards for its customers.

“Fuel Slippage” is an industry term for the fuel that you can’t account for in the actual course of business. A stolen tank of gasoline on a company fleet card or diesel saddle tank that came up empty without explanation. We are here to help stop slippage in your business.

We have strategies on how to protect yourself from internal theft, how to use prepaid and preset fuel card controls with employees, as well as securing yourself from external theft. This article is about protecting your fleet from physical fuel theft.

Fuel theft is on the rise in the Portland, Oregon area.

In Portland, Oregon with the rise of homeless campers all over our industrial areas, we have seen a increasing fuel theft. Star Oilco can help you knock out fuel theft. For as hard as fleets work to make a dollar, seeing it shrink from the bottom line due to criminal theft is an avoidable scenario. Think ahead, remove opportunity for thieves to steal, and create systems that keep honest people honest.

The biggest preventive measure Star Oilco can provide is total control of what goes into and out of your fleet. If you have a bulk tank, a tank monitor and key control cardlock system is very affordable these days, guaranteeing inventory is kept to the gallon. If you have fleets on the road without a tank please consider using Pacific Pride secured cardlock fueling in combination with Mobile Onsite Refueling of your fleet in your yard.

Stop Fuel Theft: Best Practices for Portland, Oregon

Prevent fuel theft in Portland, Oregon

To train your fleet consider the following best practices below:

1 – Educate your people on the dangers and evidence of fuel theft

Fuel thieves usually come back again and again. Make sure your whole team is aware of the mess fuel thieves usually leave behind. Transferring from a saddle tank to their vehicle or container leaves a mess. Also make sure they are aware of unsafe places. Unsecured yards, especially with homeless campers in diesel RV’s, are a prime environment to expose yourself to theft. If you are a refrigerated trailer fleet, make sure your drivers tell your clients that unattended reefer trailers are the favorite hunting ground for fuel thieves and a locking gas cap is not necessarily a deterrent.

2 – Install fences, lighting, security cameras, and work with the local police.

Vehicle yards are a popular target for fuel thieves, so make it as difficult as possible for them to get in unnoticed. Secure fencing and bright lighting make your yard far more visible from the road and less attractive to thieves. Security cameras can act as both a deterrent and an effective way to catch criminals if theft ever occurs. Also, make sure you report theft to the local police to ensure they are tracking activity. It can be discouraging given the scale of the problems in Portland right now, but the data matters.  You never know when a fuel thief will get caught for some other crime and the evidence of pumping equipment and containers will tip off the police of the culprit.

3 – Fit bulk tanks with level monitors and inventory control systems.

Inventory control systems are extremely affordable now. Not only is it a convenient tool to track tank levels for your ordering purposes and provide proof that the tank is not leaking for local environmental regulators, it will also tip you off if an odd time of day is seeing fuel drawn. Inventory control systems have also become far more affordable than they were ten years ago. Key control for turning on power to your fuel dispensing system, which will track drivers, and the equipment they are fueling (license plate, equipment number, on-road, off-road, or tax exempt status) will keep you informed.

4 – Defensive parking, landscaping and crash protection.

If it is not easy for someone to get immediately next to the fuel tanks of your vehicles or bulk tank, it is that much harder to steal. Park vehicles in a way that protects and blocks access to someone trying to operate a pump to easily reach your fuel tanks. If you are using on-site refueling, your vendor can suggest some ideas that still enable them access to your saddle tanks without problem.

5 – Communicate with neighbors, vendors, and employees that theft is suspected or definitely occurring.

Many fleets have multiple vendors access their yard at night or over weekends. Make sure those vendors are on your team and on the look out. Tire and fleet fueling services should let you know if a loiterer appears to be in your area in the middle of the night. If a gate has been tampered with or a mess is obvious inside the yard, make sure they are letting you know earlier rather than later. Also, be aware during business hours. Fuel thieves will often scope a yard during the day to target later that night. Take note of anyone acting suspiciously around your yard, perhaps engaging them to find out what they’re doing. Don’t hesitate to ask them what they are doing either. Face to face contact can encourage them to find another place to be a criminal.

If you have any questions or want our perspective we encourage you to reach out.

Do you have a bulk diesel storage tank?

Does that tank seem to have water in the bottom of it and you can’t seem to figure out where it’s coming from?

You call your diesel supplier and they say they know it isn’t them. If that’s your experience, Star Oilco can explain where that water is probably coming from. With the help of Hydrotex, Star Oilco can also lab test your fuel quality and prove we are in improving it as well.

desiccant filter in field

All storage tanks are different. But for the most part, if your tank seems to take on water randomly. It’s probably from the tank breathing. Especially if you have a large above ground tank. In fact, if you tracked it on a calendar it probably happens the same time of year in conjunction with a weather pattern your tank responds to.

How it works is as the temperature changes the tank’s space that is not filled with fuel will breathe in and out. The temperature and air pressure move air in and out of the tank. As does dispensing fuel out of the tank and then refilling the tank. When that happens, especially if you have a significant amount of humidity in the air or misting rain, water makes it’s way into your fuel supply. As temperatures change, moisture is drawn into the tank, condenses on the inner wall of the tank, and then deposits itself on the bottom of the tank.

This water not only poses a risk to your engines, but if your fuel isn’t treated for stability and performance, that fuel is guaranteed to start growing bugs and algae that will spread throughout your fleet and will have your mechanics spinning filters and dealing with random problems due to this diesel biological growth.

This problem is also exacerbated by ineffective fuel additives trying to keep your fuel dry, clean and safe for your injectors to process, which ensures that water does not get absorbed by your diesel. A single drop of water falling out of solution in today’s high pressure fuel rails and your engine can blow an injector.

HOW DO YOU SOLVE WATER IN YOUR DIESEL TANK?

ANSWER: DESICCANT BREATHERS ON YOUR VENTS

Desiccant diagram

Star Oilco recommends Donaldson desiccant filters, given their excellent full line of products and support. More on the full Donaldson Clean Dry Fuel program here: Donaldson Clean Diesel Kits Brochure.

The Donaldson desiccant breaker mounts to the top of a tank at it’s vent point. This addition seals the point of failure for water to get into your tank. Though in some cases it doesn’t stop 100% of water from ending up in your fuel tank, it definitely guarantees you know where it won’t be coming from, the environment around your tank.

(NOTE: If dealing with underground storage tanks also be aware that if you seal the vent with a desiccant filter and you still have incident’s of water, it might be a leak in the bottom of the tank where rain water is making its way into the tank.)

By using Donaldson filters, Star Oilco also gains the benefit of support from Hydrotex PowerKleen diesel fuel lab to analyze fuel to guarantee that the before and after samples of the fuel are moving as expected and the problem is solved. Running diesel samples can cost as much as $200 each time–having a partner that backs up our solutions with ASTM and ISO measured verification is a must.

The first step in getting better performance from your diesel fuel is to test your bulk diesel storage tank.
