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 Invest” program 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.

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.

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.

Renewable Diesel vs Biodiesel

What’s the difference and how do they compare in price? 

If you are looking for a cleaner and greener alternative to diesel fuel, you might have come across two options: renewable diesel and biodiesel. Both fuels are made from organic sources, such as vegetable oils and animal fats, but they have different production processes and properties. In this blog post, we will compare renewable diesel and biodiesel in terms of their pros and cons, as well as their prices and incentives in Oregon. 

What is Renewable Diesel? 

Renewable diesel is a fuel that is chemically identical to petroleum diesel, but it is made from renewable raw materials through a process called hydrotreating. Hydrotreating removes impurities and oxygen from the feedstock, resulting in a pure and refined fuel that can be used in any diesel engine without modifications or blending. Renewable diesel (R99) has a high cetane number, which means it ignites easily and burns efficiently. It also has a low cloud point, which means it can withstand cold temperatures without gelling or clogging filters. 

What is Biodiesel? 

Biodiesel is a fuel that is made from renewable raw materials through a process called transesterification. Transesterification converts the feedstock into fatty acid methyl esters (FAME), which are then blended with petroleum diesel at various ratios. Biodiesel can be used in most diesel engines, but it may require some modifications or adjustments depending on the blend level and the engine type. Biodiesel has a lower cetane number than renewable diesel, which means it may not ignite or burn as well. It also has a higher cloud point than renewable diesel, which means it may gel or clog filters in cold weather. 

The cost of renewable diesel and biodiesel depends on various factors, such as the type and availability of feedstock, the production process, the market demand, and the government incentives. In general, renewable diesel is more expensive than biodiesel, as it requires more complex processing and higher quality feedstock. According to the U.S. Energy Information Administration (EIA), the average wholesale price of renewable diesel in California was $3.06 per gallon in October 2021, while the average wholesale price of biodiesel was $2.76 per gallon in the same month. However, both renewable diesel and biodiesel can benefit from federal RIN’s and state credits such as the low carbon fuel standards, which can lower their effective prices and make them more competitive with petroleum diesel. As of July 10th of 2023 renewable diesel (R99) in Portland Oregon was 60 cents higher than biodiesel (B99). 

 Renewable Diesel vs Biodiesel Carbon Intensity 

According to CARB, the carbon intensity of biodiesel ranges from 14.85 to 67.45 gCO2e/MJ and, renewable diesel ranges from 15.84 to 62.86 gCO2e/MJ, depending on the feedstock and production pathway. The lowest carbon intensity for biodiesel is achieved by using waste cooking oil as the feedstock and renewable methanol as the transesterification agent. The highest carbon intensity is associated with using soybean oil as the feedstock and fossil-based methanol as the transesterification agent. The lowest carbon intensity for renewable diesel is achieved by using waste cooking oil as the feedstock and renewable hydrogen as the hydrotreating agent. The highest carbon intensity is associated with using soybean oil as the feedstock and fossil-based hydrogen as the hydrotreating agent.

Pros and Cons of Renewable Diesel and Biodiesel 

Both renewable diesel and biodiesel have some advantages and disadvantages compared to petroleum diesel. Here are some of the main pros and cons of each fuel:  

Renewable Diesel Pros: 

– Reduces greenhouse gas emissions by up to 75% compared to petroleum diesel 

– Reduces tailpipe emissions of particulate matter, nitrogen oxides, carbon monoxide, and hydrocarbons 

– Improves engine performance and efficiency with fewer regeneration cycles of the emissions system 

– Compatible with existing infrastructure and vehicles 

– Biodegradable and nontoxic 

Renewable Diesel Cons: 

– More expensive than petroleum diesel 

– Limited availability and supply 

– May increase emissions of sulfur dioxide 

Biodiesel Pros: 

– Reduces greenhouse gas emissions by up to 78% compared to petroleum diesel 

– Reduces tailpipe emissions of particulate matter, carbon monoxide, and hydrocarbons 

– Biodegradable and nontoxic 

– Supports domestic agriculture and energy security 

 Biodiesel Cons: 

– May increase emissions of nitrogen oxides 

– May cause engine problems such as injector coking, filter plugging, corrosion, and reduced lubricity 

– May degrade over time or when exposed to water or microbes 

Oregon Prices and Incentives for Renewable Diesel and Biodiesel 

Oregon is one of the states that has adopted a Clean Fuels Program (CFP), which aims to reduce the carbon intensity of transportation fuels by 10% by 2025. The CFP creates a market for low-carbon fuels such as renewable diesel and biodiesel by requiring fuel suppliers to either blend them with petroleum diesel or buy credits from low-carbon fuel producers. The CFP also provides incentives for consumers to use low-carbon fuels by reducing their fuel taxes. 

According to the Oregon Department of Environmental Quality (DEQ), the average price of diesel in Oregon as of November 2021 was $3.87 per gallon. The average price of biodiesel blends ranged from $3.88 per gallon for B5 (5% biodiesel) to $4.01 per gallon for B20 (20% biodiesel). The average price of renewable diesel was $4.05 per gallon. As of July 2023 the price of renewable diesel (R99) in Oregon was 50 to 60 cents higher than biodiesel (B99). 

The DEQ also provides a Fuel Cost Calculator that allows consumers to compare the costs and benefits of different fuels based on their vehicle type, fuel efficiency, annual mileage, fuel price, carbon intensity, and tax rate. According to the calculator, using renewable diesel instead of petroleum diesel would save an average consumer $34 per year in fuel costs and reduce their carbon emissions by 1.6 metric tons per year. Using biodiesel instead of petroleum diesel would save an average consumer $12 per year in fuel costs and reduce their carbon emissions by 0.8 metric tons per year. 

Renewable diesel and biodiesel are both viable alternatives to petroleum diesel that can help reduce greenhouse gas emissions and support renewable energy sources. However, they also have some trade-offs in terms of cost, availability, performance, and emissions. Consumers should consider their vehicle type, driving habits, fuel preferences, and environmental goals when choosing between these fuels. Oregon offers some incentives and programs to encourage the use of low-carbon fuels such as renewable diesel and biodiesel, which can help consumers save money and reduce their carbon footprint.

The Pros and Cons of Renewable Diesel in Your Diesel Truck 

 As the world continues to become more aware of sustainable alternatives, renewable biodiesel (otherwise known as R99) has emerged as a promising solution to reduce carbon emissions in the transportation sector. Diesel truck owners, for example, may wonder whether they can switch to renewable diesel and contribute to a greener future as the city of Portland will be enforcing new restrictions and limitations on carbon emissions. Here is more information on the feasibility of using renewable diesel in diesel trucks and looking at the benefits and possible challenges. By understanding the advantages and limitations, you can make an informed decision about integrating this renewable fuel into your trucking operations.

1. Understanding Renewable diesel:

Renewable diesel is a clean-burning alternative fuel derived from natural sources such as vegetable oils, animal fats, and recycled cooking oil. It is produced through a process called transesterification, where the oils or fats are chemically reacted with alcohol to separate the glycerin from the fatty acids, resulting in renewable diesel. This sustainable fuel can be used in diesel engines with little to no modifications, making it a viable option for diesel truck owners. 

 

2. Environmental Benefits of Renewable Diesel:

Renewable diesel (known as R99) has significant environmental benefits. Renewable diesel reduces greenhouse gas emissions, such as carbon dioxide, sulfur dioxide, and particulates matter, compared to traditional diesel. It has lower levels of harmful pollutants, contributing to improved air quality and reduced smog formation. Additionally, renewable diesel is biodegradable, non-toxic, and significantly minimizes net carbon dioxide emissions over its lifecycle, making it a valuable tool in mitigating climate change. 

 

3. Compatibility and Performance:

While renewable diesel is compatible for diesel engines as a drop in solution, its essential to consider any factors before switching. Renewable diesel has a slightly lower energy content than regular diesel, which can result in a slight decrease in fuel economy.

 

4. Availability and Infrastructure:

Is renewable diesel readily available? While renewable diesel is becoming more widespread, its availability may vary depending on your location. Star Oilco offers delivery of renewable diesel (R99) to the Portland, Oregon surrounding area as well as Vancouver, Washington. You can reach out to us to get a quote based on your location and service needs.

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.

What is red diesel?

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 price.  This 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.

What is green diesel?

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.

What is dyed diesel?

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.

What color is dyed diesel?

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.

What is the red dye used to turn off-road diesel red?

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.

Is dyed or off-road diesel flammable?

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.

What is the difference between off-road diesel and on-road diesel?

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.

Is off road diesel bad for a diesel pick up or heavy duty truck?

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.

Why is it illegal to use off-road diesel in a pick up truck or commercial truck?

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.

Is dyed diesel #1 or # 2 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.

Is dyed diesel and off-road diesel kerosene?

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 diesel.  Not 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.

Is dyed diesel and off-road diesel stove oil?

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.

Is off-road diesel bad for my truck?

Depends on the year of your truck, and we assume you mean red dyed diesel fuel.  First, using dyed diesel, off road diesel, or heating oil in an on-road vehicle is against the law.  If 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 avoidance.  Beyond the legal use of off-road fuel.  Typically 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.

Is dyed diesel or off-road diesel heating oil?

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.

Does off-road diesel have sulfur in it?

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.

Does off-road diesel freeze?

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.

Does off-road diesel gel in cold weather?

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 Fahrenheit.  If 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.

How long can I store off-road or dyed diesel in a fuel tank?

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.

What are the fuel taxes on off-road diesel?

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).

Do you pay sales tax on dyed diesel or off-road diesel in Washington state?

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. 

What are the taxes on dyed diesel or off-road diesel in Oregon state?

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.

Is there a way to buy clear diesel without a road tax on it?

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.

Can you use dyed diesel in a diesel pickup truck?

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.

How does the government test if someone used dyed diesel?

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 color.  Those kits will not remove enough dye to avoid detection by these lights.

Why is off road diesel illegal for pick up trucks to use?

Off road diesel is dyed red to show that the on-road fuel taxes are not paid or that it is a tax-free fuel.  The Federal Government and State Government’s have fuel taxes for on-road fuel usage to help pay for the roads we all drive on.  If 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 seen.  Regulators 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.

What is the difference between dyed diesel and heating oil?

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.

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.

How do I order off-road diesel for a construction project?

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.

How do I stop biological growth in my off-road diesel fuel tank?

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 use.  Our recommended fuel additive is a fuel microbiocide with stability additives made for diesel long term storage.  This kills and prevents the growth of biological “hum-bugs” in your tank.  Bacteria, 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).

How do I get water out of my off-road diesel equipment's fuel tank?

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 tank.  If 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 grow.  If 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. 

Where can I buy off-road diesel or dyed diesel?

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.

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.

Off-road diesel is an important fuel that powers heavy equipment and machinery for industries like construction, farming, and transportation. It’s a popular choice because it’s affordable and reliable for tough jobs that need a strong energy source. In the Portland, Oregon metro area, fuel rules are getting stricter, especially with laws pushing for cleaner, renewable fuels. That means businesses using off-road diesel need to stay informed about the latest regulations and fuel options to keep running smoothly and legally.

This guide breaks down everything you need to know about off-road diesel, including how it’s used, the laws surrounding it, and its impact on the environment in Portland. It also looks at the challenges and benefits of switching to cleaner fuels. Whether you run construction equipment or want to learn more about renewable diesel options, this guide will help you understand what’s needed to keep up with Portland’s changing fuel standards while keeping costs low and reducing pollution.

1. Definition and Uses of Off-Road Diesel 

Off-road diesel, often referred to as “dyed diesel,” is a specialized fuel used exclusively in off-road applications. It is chemically identical to on-road diesel but contains a red dye that differentiates it for regulatory purposes. 

Common Applications of Off-Road Diesel: 

  • Construction equipment such as excavators, bulldozers, and cranes. 
  • Agricultural machinery like tractors and combines. 
  • Generators and other stationary equipment used on job sites. 
  • Marine vessels operating in inland or coastal waters.

The red dye in off-road diesel is a critical feature that ensures compliance with tax exemptions and usage restrictions mandated by federal and state regulations. This dye serves as a visual marker to easily differentiate untaxed off-road diesel from its taxed on-road counterpart, streamlining inspections and enforcement efforts. By law, off-road diesel is specifically designated for vehicles and machinery that operate exclusively off public roads, such as construction equipment, agricultural machinery, and generators. The red coloration not only identifies the fuel’s intended purpose but also acts as a deterrent against improper use in on-road vehicles, where the financial and legal penalties for misuse can be significant. Using red-dyed diesel outside its prescribed applications is considered tax evasion and can result in hefty fines and legal consequences. This visible distinction ensures transparency and accountability in fuel usage while supporting the infrastructure and industries reliant on off-road diesel.

2. Legal Considerations 

While off-road diesel is essential for many industries, it comes with strict legal guidelines. Using dyed diesel in on-road vehicles is a serious offense. 

Penalties for Misuse: 

  • In Oregon, using off-road diesel in on-road vehicles can result in fines of up to $10,000 per day. State authorities regularly perform roadside inspections to ensure compliance. 
  • Misuse can also lead to the revocation of fuel tax exemptions for businesses. 

To avoid these penalties, businesses must implement strict protocols to ensure the proper segregation of fuels and comprehensive employee training on the correct applications of dyed diesel. This includes maintaining dedicated storage tanks for dyed diesel to prevent accidental contamination with on-road fuel. Employees should be educated about the legal ramifications of misuse, as well as the operational differences between dyed and clear diesel. Regular audits of fuel usage logs and equipment can further enhance compliance. Additionally, businesses can leverage technological solutions like fuel monitoring systems to track usage and ensure that dyed diesel is utilized exclusively for off-road applications. Such measures not only mitigate the risk of hefty fines but also promote efficiency and accountability within operations, safeguarding the reputation and financial stability of the organization. 

3. Portland’s Renewable Fuel Standard 

Portland has been at the forefront of adopting renewable fuel standards (RFS) to reduce its carbon footprint. These standards directly impact off-road diesel and its renewable counterparts. 

Phased Renewable Content Requirements: 

  • By 2024, diesel sold in Portland must contain at least 15% renewable content. 
  • By 2030, this requirement will increase to 99%, effectively transitioning the market towards renewable diesel and biodiesel.

This specialized fuel ensures that vital machinery operates efficiently, supporting economic activities and maintaining productivity in diverse sectors.

Is it legal to use off-road diesel in on-road vehicles?

No. Using dyed diesel in on-road vehicles is illegal and subject to significant fines due to its tax-exempt status and the strict regulations governing its use. These penalties are in place to ensure that dyed diesel is only utilized in its intended applications, such as off-road equipment and machinery. Enforcement agencies conduct random inspections and fuel tests to identify misuse, which can result in fines up to $10,000 per day in Oregon. Misusing dyed diesel not only leads to financial repercussions but also undermines the funding mechanisms for road maintenance, as road taxes are critical for infrastructure development. Businesses and individuals must remain vigilant and ensure compliance to avoid these severe consequences. 

What are the environmental impacts of off-road diesel?

Traditional off-road diesel contributes significantly to air pollution due to the release of greenhouse gases, particulate matter, and nitrogen oxides during combustion. These pollutants have far-reaching impacts on air quality, public health, and the environment, especially in urban areas like Portland where industrial and construction activities are prevalent. In contrast, renewable alternatives such as biodiesel and renewable diesel dramatically reduce emissions, including carbon dioxide and harmful particulates, making them a more sustainable choice. These renewable fuels are produced from non-petroleum sources such as waste oils, animal fats, and plant-based feedstocks, which not only lower their carbon intensity but also promote a circular economy. The adoption of renewable diesel in off-road applications aligns with Portland’s goals to reduce its environmental footprint, improve urban air quality, and mitigate climate change effects, setting a model for cleaner industrial operations statewide. 

Is off-road diesel flammable?

Yes, off-road diesel is flammable and must be handled and stored with care. Due to its combustible nature, it’s essential to follow strict safety protocols when storing and transporting off-road diesel. Fuel should be kept in approved containers that are properly sealed to prevent leaks and vapor release. Storage areas should be well-ventilated and located away from sources of heat or open flames to minimize the risk of ignition. Additionally, fire suppression systems and emergency response plans should be in place in facilities where large quantities of off-road diesel are stored. Regular maintenance of fuel storage tanks, including inspections for corrosion or damage, further reduces the risk of accidents and ensures the long-term safety and integrity of the fuel. 

How does cold weather affect off-road diesel?

Cold temperatures can cause diesel to gel, significantly impacting engine performance and fuel flow in off-road equipment. As temperatures drop, the paraffin wax in diesel begins to solidify, creating a thick, gel-like consistency that can clog fuel lines and filters. This issue is particularly concerning in Portland during the winter months, where subfreezing conditions are common. To prevent gelling, operators should consider using anti-gel additives specifically formulated for cold weather. These additives lower the fuel’s pour point and cold filter plugging point, ensuring that diesel remains fluid even in extreme temperatures. Additionally, preheating fuel tanks or using insulated storage solutions can further mitigate the risks associated with cold weather. By taking these precautions, businesses can maintain operational efficiency and avoid costly downtime caused by gelled diesel.

Are there tax implications for using off-road diesel?

Off-road diesel is exempt from road taxes, which makes it a cost-effective choice for industries operating heavy machinery and equipment. However, this tax exemption comes with stringent regulations to ensure that the fuel is used exclusively for its intended off-road purposes. Misuse, such as using dyed diesel in on-road vehicles, can lead to severe penalties, including fines of up to $10,000 per day in Oregon. Enforcement agencies frequently conduct inspections to detect improper use, emphasizing the importance of compliance. Businesses must educate their teams on proper fuel usage, maintain accurate records, and implement strict oversight to prevent accidental or intentional misuse. Beyond financial implications, non-compliance can damage a company’s reputation and disrupt operations.

What are the latest regulations regarding off-road diesel emissions?

Portland’s renewable fuel standards mandate increased renewable content in diesel, progressively reducing emissions over time and setting a strong example of environmental leadership. These standards not only focus on lowering greenhouse gas emissions but also encourage the adoption of innovative fuel technologies like renewable diesel and biodiesel. By requiring a phased increase in renewable content, the city ensures a gradual yet impactful transition, giving industries the time needed to adapt while aligning with long-term climate goals. This approach supports local economic growth by fostering investments in renewable energy infrastructure and creating opportunities for green technology advancements. As businesses comply with these standards, Portland strengthens its position as a pioneer in sustainable urban development. 

How can I identify if my diesel fuel is dyed or not?

Dyed diesel is visually identifiable by its red color, distinguishing it from clear (on-road) diesel. The red dye is added to off-road diesel as a regulatory marker to signify its tax-exempt status and restricted use in off-road applications. This vivid coloration ensures easy identification during inspections and helps prevent accidental or intentional misuse. While chemically identical to on-road diesel, the presence of the dye plays a crucial role in compliance and enforcement, allowing authorities to quickly verify that fuel is being used appropriately. This distinction is essential for maintaining the integrity of tax systems that fund public infrastructure while supporting industries that rely on cost-effective fuel solutions. 

What are the differences between dyed and clear diesel fuels?

Dyed diesel is exclusively designated for off-road use and benefits from tax exemptions, making it a cost-effective option for industries that rely heavily on heavy-duty equipment and machinery. In contrast, clear diesel is taxed to fund public road infrastructure and is mandated for use in on-road vehicles. The differentiation is not merely a technicality but a legal requirement, with dyed diesel being subject to strict usage regulations. This separation ensures that industries using off-road diesel gain economic advantages while maintaining compliance with tax laws designed to support public infrastructure projects. The clear distinction between dyed and clear diesel fuels helps streamline enforcement and minimizes misuse, ensuring fairness and accountability in fuel taxation systems. 

How does the sulfur content in off-road diesel affect its use?

Off-road diesel is typically ultra-low sulfur diesel (ULSD), which reduces harmful emissions and complies with environmental regulations. The transition to ULSD represents a significant step forward in minimizing the environmental impact of diesel fuel. By drastically reducing sulfur content, ULSD helps to lower the emissions of sulfur dioxide, a major contributor to acid rain, and particulate matter, which is harmful to respiratory health. This compliance with environmental standards is particularly important in urban areas like Portland, where air quality is a key concern. Furthermore, ULSD enhances the performance of advanced emission control technologies, such as diesel particulate filters (DPFs) and selective catalytic reduction (SCR) systems, allowing modern engines to meet stricter emissions requirements. The widespread adoption of ULSD underscores the diesel industry’s commitment to sustainability while ensuring that off-road diesel remains a reliable and efficient energy source for heavy-duty applications.

What are the best practices for storing off-road diesel to prevent gelling?

Use insulated or heated storage tanks and anti-gel additives during colder months to maintain fuel quality. Insulated tanks help to regulate temperatures, preventing the fuel from reaching conditions where gelling typically occurs. Heated storage options further ensure that the diesel remains fluid, even in extreme cold, by maintaining a consistent temperature above the gelling threshold. Anti-gel additives work by lowering the pour point and cold filter plugging point of the diesel, allowing it to flow smoothly through the fuel system. Additionally, regular monitoring of fuel tanks for condensation or water contamination is crucial during winter months, as water can exacerbate gelling issues. Combining these strategies provides comprehensive protection against cold-weather challenges, ensuring that equipment operates reliably in harsh conditions.

Off-road diesel is an indispensable resource for industries operating in the Portland metro area, serving as the backbone for critical operations in construction, agriculture, and logistics. Understanding the nuances of its uses, from powering heavy machinery to fueling generators, is essential for businesses aiming to maintain seamless operations. Moreover, staying informed about the legalities and environmental impacts of off-road diesel ensures compliance with stringent state and federal regulations, protecting businesses from costly penalties. As Portland takes bold steps towards adopting renewable diesel, industries have the opportunity to align their fuel strategies with the city’s ambitious sustainability goals. Embracing these changes not only reduces carbon footprints but also positions businesses as leaders in innovation and environmental stewardship, fostering a competitive edge in an increasingly eco-conscious market.

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.

Diesel 1 vs Diesel 2

Diesel 1 and Diesel 2 can often bring confusion when it comes to understanding what the differences are between them. Consumers can have confusion about which one is best for their equipment or their business. Whether they’re looking for improvements in quality, igniting quickly with its high cetane rating for easy starts in cold weather or ensuring overall efficiency with engine performance and lower maintenance needs. We will explore the differences between Diesel 1 and Diesel 2 and help you understand the benefits of each. 

Key distinctions between the properties of Diesel 1 and Diesel 2 

Before you invest your hard-earned money in fuel that might not be suitable or, even worse, could harm your vehicles and equipment, let’s clear the air. Let’s simplify the differences between Diesel 1 and Diesel 2 in a way that’s easy to follow and gives you the confidence you need. 

Sulfur Content

Diesel 1: Lower sulfur content, reducing sulfur dioxide emissions and aligning with environmental standards.

Diesel 2: Higher sulfur content for specific applications with advanced emissions control. 

Cetane Number

Diesel 1: Boasts a higher cetane number (ignition quality of diesel fuel), ensuring better ignition and smoother combustion, especially in cold weather.

Diesel 2: It has a lower cetane number and is optimized for slightly delayed ignition in engines designed for this grade. 

Viscosity

Diesel 1: It generally has a lower viscosity, facilitating smoother fuel flow and distribution. 

Diesel 2: Its higher viscosity may require specialized fuel systems designed to handle its thicker consistency, such as generator power plant engines or industrial machinery. 

Cold Flow Properties

Diesel 1: It excels in cold climates because it contains kerosene and lacks paraffin, which prevents the diesel from gelling in colder temperatures. So, it’s best for the residents of the coldest regions.

Diesel 2: This fuel needs additional winterization measures in extremely cold temperatures, like mixing Diesel 1 (20%) with Diesel 2 (80%) and additives to lower the viscosity of Disesel 2. But make sure that your vehicle’s engine is capable of handling it.

Additives

Diesel 1: Contains extra constituents that improve cleanliness and lubrication and reduce rusting effects due to corrosion inhibitors in the engine. It also has demulsifiers that separate water from the fuel system and prevent engine problems. 

Diesel 2: Generally has fewer additives; common ones decrease viscosity for more accessible engines starting in cold conditions. Due to the higher wax content, some other chemicals are infused within it to stop the accumulation of wax sediments. 

Engine Wear and Tear

Diesel 1: Gentle on engines with low wax content, anti-corrosive additives, and high cetane rating, resulting in less wear, lower maintenance, and a longer lifespan. 

Diesel 2: Causes more wear, but viscosity contributes to enhanced lubrication and mitigates engine damage by reducing friction. 

Sound

Diesel 1: Less noisy due to its high cetane rating, ensuring rapid ignition and reducing the usual knocking sound linked with diesel engines. 

Diesel 2: Tends to be noisier due to a lower cetane rating and a longer combustion process. Results in higher levels of heat and pressure for a louder engine. 

Smoke Release

Diesel 1: Emits less smoke due to quick ignition and cleaner exhaust due to lower wax levels, demulsifiers, and other additives that cause smoke. 

Diesel 2: Results in smokier emissions because of a lower cetane rating, slower ignition, and increased accumulation of unburned fuel. 

Fuel Energy Efficiency 

Diesel 1: Slightly lower fuel economy (miles per gallon) than Diesel 2 due to its lighter grade and lower heating value. 

Diesel 2: It burns more slowly and proves to be the superior choice for extended highway travel, optimizing efficiency and minimizing refueling stops.

Cost

Diesel 1: It comes at a slightly higher cost because it is enhanced with lubricants, reducing friction for efficient fuel system operation. The premium diesel D1 has more benefits, like reduced repairs.  

Diesel 2: Represents a more economical choice. Despite lacking premium additives, more miles per gallon and a higher heating value make it the least expensive option at the pump. 

Finding the Right Fuel Fit: Diesel Decisions 

Selecting the appropriate diesel for your vehicle is crucial, and it all comes down to your vehicle type, usage, and environmental conditions for optimal performance. Diesel #2 is cost-effective and versatile for everyday commuting, while Diesel #1 is ideal for high-performance or newer engines due to its higher cetane rating.  

Trucks and heavy-duty vehicles benefit from Diesel #2’s versatility and cost savings. In fleet management, Diesel #2 is practical for various vehicles. Diesel #1 is the choice for lower emissions compliance in environmentally strict areas. Always check your vehicle manual for specific recommendations. 

Diesel 1 and Diesel 2 bring unique qualities to engines and the environment. Diesel 1 is cleaner and ideal for high-performance engines and excels in colder climates. Diesel 2, versatile and cost-effective, suits everyday driving and heavy-duty vehicles.  

Understanding these distinctions empowers you to make informed diesel decisions, ensuring engine longevity and environmental responsibility.
