Diesel Backup Tanks – Treating and Refilling

Here’s good advice if you are relying on diesel as a back up fuel in the Pacific NW.

Now is the time to refill and treat your back up fuel tanks.

Diesel as a back up fuel

Quite a bit of our business at Star Oilco is fueling back-up generators, emergency water pumps, refrigerated trailers and other long term off-road diesel storage requirements. In the Pacific Northwest, biodiesel blending is required by state laws and you need to take an extra duty of care when storing diesel as a back-up fuel.

This means that most off-road diesels and heating oils are ultra low sulfur diesel containing a small quantity of biodiesel.  That means long term storage requires a proactive approach.  You can’t just hope and wait to see what the fuel begins to look after years of storage.

Technical advice from Government Fleet Magazine to help you with storing diesel fuel.

Here is an article from Government Fleet Magazine on the subject which runs through the specifics of long term storage and what causes fuel to degrade when stored.  Government Fleet Magazine – How to Maintain Stored Diesel Fuel.

Star Oilco has also worked up a PDF check list on how to verify if your fuel is in need of freshening or is still in emergency ready shape.  If you are a customer of ours, we will deliver a laminated card version to keep next to your back up generator. If you are not a customer (or outside of our service area) drop us a message below and we will gladly email you the PDF.

For our customers, we recommend that you check the tank bottom fuel quality on an annual basis to make sure the product looks good. If the tank has sat for years and is dark in color (good diesel is bright and transparent – you will notice if it is in bad shape), we recommend pumping the tank out at least partially and replacing with fresh fuel. Often you can also hugely improve the quality of the fuel by polishing the fuel. Polishing is when you circulate fuel from the bottom of the tank through a pump, filter repeatedly in order to remove any sediment or growth from the fuel, and then place this fuel back in the same tank.

Look at your fuel for a bright and clear color.

For stored fuel, you also want to make sure it is stabilized and contains a biocide. Stabilizers prevent the oxidation of the fuel and prevent the effect of metals like lead, copper and zinc, which can react and degrade fuel. For heating oil systems with a return line, for instance, the fuel is flowing through a copper line to the furnace and then back to the tank in a return line.

Use additives designed to prolong the life of your emergency diesel fuel.

Biocides prevent the growth of biological activity in the tank. In scenarios whcontaminated_dieselere micro-organisms like algae, bacteria, yeasts, and other bugs are growing in your fuel, biocides can kill this growth. It is still important to remove the residual grit and other contaminants that are the hallmark of bugs growing in your tank. Usually you remove them by filtration or total turn over of the fuel. If your tank absolutely has to be clean, you can contract a tank professional to enter the tank and physically clean the tank bottom or reline the tank with either fiberglass or an epoxy resin.

Water in diesel destroys fuel quality rapidly. Check your tank for water every fall and spring.

In events where water finds its way into your storage tank, that can also be corrected by pumping the tank bottom. Additionally, you want to put in an absorbent material designed to absorb water and not fuel. If your long term storage tank has water and you are not planning to burn 100% of the fuel in the near future, DO NOT add anything that removes water by distributing into the fuel. Adding a “fuel drier” that actually pushes the water into solution with the diesel will worsen the long term quality of your fuel, not improve it. That water is where bugs find their home to grow in fuel.

Star Oilco will test your fuel at no charge if you have an open account.

Feel free to call us with any questions you may have about long term storage of diesel. Star Oil can also deliver treated diesel ready for long term storage complete with Hydrotex PowerKleen Premium Diesel additive to improve the long term storage quality of your fuel. For biocide, we use Valvtect BioGuard fuel microbiocide to kill any possible biological activity and prevent any chance of it starting.

Seize Control of Your Fuel Spending with Pacific Pride Cardlock

A Pacific Pride Cardlock Card gives you the ultimate control over when and where fuel is purchased. Plus, we guarantee the highest level of control by offering human support to make it easy for a small business. You have enough to manage and don’t need another website to log into! Know who bought what, when, and where — in real time — to better manage the buying decisions by your drivers.

Pacific Pride, CFN, WEX, Voyager and other fleet cards all have similar tools. But with Pacific Pride Cardlock, you’ll benefit from stand alone commercial fuel sites that are available 24 hours a day, 7 days a week, 365 days a year.

In Oregon, the minimum wage is rising and that means the retail price of fuel is rising to pay for those wages.  While other cards require you to wait in line and pay someone to fuel your vehicle in Oregon, Pacific Pride stand alone cardlock locations avoid that needless labor and allow your business to serve itself around the clock. Get out of fuel lines and save on your total cost of fuel.

Beyond the time and money savings of avoiding retail fuel lines, Pacific Pride cardlock also is far more secure to protect you from someone stealing fuel with your fleet card. Star Oilco’s Pacific Pride cardlock offering has a single simple tool for you: a human being on the other side helping make sure the total program is working. We help you grab control of every drop, dollar and driver.

            We are your partner in Fleet Card and Cardlock Card success.

Star Oilco goes one step further than our competitors by keeping things simple and easy for you. This is done with the obvious human element and best practices that complete the full value that a secured fuel card offers.

Call us and have us take care of that for you. You tell us what you want, we’ll consult with you and you’ll get a working card program.

This is what we recommend for your non-management cards:

  1. Secure your fleet card to a vehicle (attached to the license plate on the bill or place the fleet card on the key ring of the vehicle).
  2. Designate your vehicle cards to only work in the state’s zip codes that you service during the times of day you operate as a business.
  3. Give each driver a unique and secret PIN attached to their name (so when they use a card, their name appears on the bill next to the transaction).
  4. Implement a “No Tolerance Fuel Theft Policy” with your Human Resource policy. Have every employee sign a contract with your business that they own their personal secret PIN and it is only for them to use. Star Oilco can provide a recommended policy for you to use. Then, if they share their PIN with someone else, they will be responsible for anything that happens. If theft is happening, it is a “No Tolerance” dismissal offense on the first occurrence.
  5. Use the e-receipts to see in real-time fuel purchases. An electronic receipt is emailed to your Controller or Dispatcher to watch for off-policy fuel usage in real time, which allows your Dispatch or Management to respond the same day to questionable decisions around fuel cards.

                  Imagine how this works for your business in practice

You can set up restrictions by days of the week, hours of the day or even by zip codes. If your business does not operate on weekends, turn off the fuel cards during the times you do not operate. If your fleet is never on the road before 7am and is back at home by 7pm every night, set up those time restrictions to make it that much harder for fuel theft to occur. If you need to update this, change something, order cards, etc., just call our office and we take care of that update for you.

With our e-receipts, your Dispatch will get an email every time fuel is purchased. You will see where, what, when and with whom this occurs. You can reinforce your company fuel policies at the local level the same day — No more waiting for the bill to see if a driver did something that cost you money. By seizing control of your fuel, your drivers will also respond to your new level of control as well. By having control and transparency of what your drivers do, they will require less management as they know you are watching.

Often the most controllable expense related with fuel is the fuel that might slip through a business due to unethical employees or outside theft. Fuel slippage is the industry term for unauthorized fuel taking. With Pacific Pride cardlock fuel, you can take control over fuel purchases and avoid the loss up front with card controls. Contact Star Oilco for a total fuel security solution for your business.

What’s in a “Keep it Simple Fuel Audit” 1024 683 Star Oilco

What’s in a “Keep it Simple Fuel Audit”

How do you compare different fuel card vendors?

You audit your fuel bill.

We will help you clarify your bill by showing what you pay, what’s in that cost of fuel, and how you can save going forward. We do this by concentrating on one fact: there are only three fees in the total cost of a gallon of gas or diesel.

The three verifiable costs in a gallon of fuel are:

  1. The commodity cost of fuel (the wholesale and verifiable fuel cost itself),

  2. The fuel taxes charged by the feds, state, and local governments on top of that, and;

  3. The margin your fuel vendor puts on top of those two very transparent costs.

Fuel bill audit best practices

Tax time is a good time to revisit your policies and systems.

Let us audit your bill and catch inconsistencies and over charges.

We have a transparent way to analyze your fuel expense that breaks it down in an easily understood format. Our approach will demystify what you’re paying in fuel so you can grab control of your gasoline and diesel bills. Our mission is to ‘Keep it Simple’ and make fuel make sense. There are several types of expenses that get added to your cost of fuel.

Pacific Pride Fuel Security

At Star Oilco, we ‘Keep it Simple’ when analyzing fuel bills.

Today, two trends can be witnessed in the Pacific Northwest: fuel prices are all over the place, and wages are rising against that trend. This makes managing for a low cost of gasoline or diesel extremely hard given the labor that might be involved in chasing that price.

Add to that the fact that retail gas stations are keeping more margins than ever in retail fuel history. With minimum wage at $15 in parts of the Pacific NW, the cost of retail gas stations is rising faster than inflation.

Stand-alone commercial cardlock locations such as Pacific Pride and CFN help you save on your own labor, as well as avoid the higher retail cost. One additional feature is you can audit a commercial cardlock fuel seller against the commercial wholesale rack price. Retail sellers promising discounts are discounting from a posted price that is based solely on what they decide a good price can be. Today, that’s a historically high margin above wholesale cost price.

Dig into your bill for an understanding of what you are paying and what you are paying for. Let us demystify the fees, charges, and hard-to-understand line items of our competitors. It seems that many of our competitors, much like cell phone companies, want to give you a bill that is as complex as possible so it’s difficult for you to understand your cost of fuel.

We can clarify your bill by showing what you pay, what’s in that cost of fuel, and how you can save going forward. Commodity cost of the fuel, fuel taxes and the margin of the vendor make up every fuel bill.

Wholesale Fuel Cost + Taxes + Margin = Total Fuel Cost

These three costs can be audited and confirmed. When we quote a prospective customer, we take their existing fuel bill and break it down into a spreadsheet that is easy to understand thanks to these definable costs. Take your existing fuel bill. Choose a few locations that are most commonly used by your fleet. Usually just the two most-used sites are enough to gauge if savings can be gained by changing vendors. Focus on the cost there, as this simplifies your focus as a representative sample of your fuel expenses.

In a spreadsheet, make easy-to-read tabs for each fuel and location. Then gather the dates fuel was bought at each location. Place the date and the price per gallon paid in their own columns. Now you know your cost. In the next column, enter the wholesale price of fuel to compare. This is going to be pretty close to what your fuel vendor was paying for it on that day give or take a few pennies.

The commodity cost of fuel is established in the market. Though different size players have discounts, these discounts are usually pennies per gallon and aren’t substantial overall. You can request a 30 day free trial of the Oil Price Information Service or “OPIS” for your local wholesale market for fuel. Government bids often use this service as a transparent bid price for fuel. NOTE: If you are buying with a Pacific Pride or CFN fleet card that uses stand-alone 24-7 commercial cardlock sites, the price will be based on OPIS as well. If you want help with this, Star Oilco can provide you with a copy of OPIS.

After that, the next column is the fuel taxes on that fuel. In another column next to the wholesale cost of fuel, you place the local taxes associated with that fueling site. Your state will usually have a “Fuel Tax Group” or some variation of that name where the state’s website will list all state and municipal taxes.

After seeing the wholesale cost and fuel taxes charged, all that remain is the margin. Many fuel sellers will try to complicate this by passing costs through, but at the end of the day, this is still their markup regardless of what they call it. This enables you to really have a discussion on what price you are charged to use their fleet card.

Our next step is to determine the typical margin you are being charged. Take the real price you paid on a day. Your next column on the spreadsheet will be the following formula:
NOTE: Margin Charged is the result that should be in your new column.

(Cell with the ACTUAL PRICE PAID) – (Cell with the WHOLESALE COST) – (Cell with FUEL TAXES) = MARGIN CHARGED

If you line up all the days for MARGIN CHARGED and average those (select a cell at the bottom of the column and type “=AVG” and select the data in the MARGIN CHARGED column), you will find the average margin. Usually this is about the same on every one of the sheets for the type of fuel you are buying. Diesel and gasoline margins are typically different. Retail gas stations, in particular, will treat diesel like a premium product so don’t be surprised if those margins are over $.40 a gallon in some places.

If you want help with this, call us!

We will empower you with the knowledge of what your vendor is charging you and determine if it is a fair price for the service. Beyond that, there should be no other costs. If your vendor has other costs (fees, invoice charges, etc.), we’ll show you what those really cost per gallon so you understand your true cost fuel.

Star Oilco makes this clear and easy to understand. Let us know if we can help.

Save money with a commercial fuel card

Save money with a commercial fuel card by avoiding the credit card retail price and preventing fuel theft in your business.

How do you avoid the higher credit card prices at gas stations?

Buy Your Fuel at a Commercial Cardlock

Make sure that employee fuel theft is not robbing from your bottom line.

 

 

  • Buy Diesel from Pacific Pride and CFN Commercial Cardlocks over retail gas stations.
  • Use a secure Fleet Card that ensures that employee theft is locked down.
    • Make sure your company’s Fleet Card is secured for:
      • A Fleet Card attached to the individual vehicle with a secure identifiable PIN for each employee.
      • Only the times of day you operate.
      • Only the days of the week you operate.
      • Only the fuel products your vehicle uses.
      • A limited number of transactions a day to ensure if a card gets misused the amount is extremely reduced.
      • A real time “E-Receipt” that notifies you of fuel purchases in real time to better manage employees for your fuel costs.

Wholesale pricing at a Pacific Pride commercial cardlock

 Take control of your fuel spend by buying wholesale instead of retail gasoline.

Over the last year fuel costs have jumped to record highs.   Retail gas and diesel prices in particular are high compared to wholesale market purchasing opportunities for fleets.  Retail posted prices for credit card purchases further increase the cost on your business.

Commercial gas station cards that direct your fleet to buy fuel at convenience stores cost far more than the posted price for fuel.  Many of these gas stations also price diesel fuel with the same mark up as premium gasoline. By getting your employees out of the retail fuel line save in several ways.

How do you save with Commercial Cardlock over a retail gas station?

PRODUCTIVITY – Get out of retail gas lines and self serve your fleet 24-7-365.

PURCHASE CONTROLS – Lock down your fleet cards by vehicle, fuel type, time of day, and Zip Codes to ensure a either a well meaning employee doesn’t buy the wrong product or  a stolen wayward card does not rob from your bottom line.

WHOLESALE AVERAGE BASED PRICING – Buy your diesel and gasoline from a verifiable wholesale index.  Pacific Pride Commercial Cardlock sites are all based from an auditable OPIS Average market index plus our agreed margin. Know what and why you are paying for fuel.  (NOTE: Star Oilco will gladly help you audit your current fuel purchase program)

FLEXIBLE – Star Oilco can combine our fleet card program with Mobile Onsite Fueling and our billing simplifies your fuel program management by consolidating all purchases by your license plates on one invoice. Our Mobile Onsite Fueling and Commercial Cardlock invoices are combined showing you all purchases on one invoice also available for export in a CSV file.

You will first of all pick up productivity, a lack of managerial control, as well as a system that conceals employee theft is tied to the cost of buying fuel.  Move your fleet fuel purchases to Pacific Pride’s network card and save per gallon as well by restricting the fuel purchases you would not want.

Now is the time to look at your total cost of fuel

Let us help you audit your fuel program

We will help you clarify your bill by showing what you pay, what’s in that cost of fuel, and how you can save going forward. We do this by concentrating on one fact: there are only three fees in the total cost of a gallon of gas or diesel.

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.

To get a complementary ASTM diesel fuel test, contact Star Oilco for assistance.

Donaldson Filter has a great educational video about the high stakes importance of aggressive filtering of your diesel prior to going into your fleet. Today aggressive filtering and ongoing quality assurance of your fuel is a must. Star Oilco calls this Precision Fuel Management and we offer it to all of our bulk fuel customers.

Precision Fuel Management is the ongoing improvement of your diesel fuel quality.

This is done by adding aggressive Donaldson filtration to the dispenser on your diesel tank or filtering fuel on Star Oilco’s Mobile Onsite trucks when wet hosing our customers). For bulk storage tanks, we include a Donaldson desiccant breather to the vent on your tank to scrub moisture from the air as it is pulled into your tank, as well as Hydrotex PowerKleen Premium Diesel Additive. In addition to these best practices Star Oilco will also sample your tank bottom, as well as take a representative sample out of your diesel nozzle and lab test this fuel according to the ULSD ASTM standard D975, as well as check for the ISO cleanliness level of your fuel. We test twice a year going into Summer and Winter to confirm if there is water on the bottom of your tank as well as any worries about dirt, biological growth, or any other recurring, but preventable fuel quality problems.

NOTE: ASTM D975 is the specification for ultra low sulfur diesel in the United States. ISO Cleanliness is a standard to check for microscopic dirt that can harm the performance of your engine systems long term if it’s getting past your engine filtration.

Diesel technology has advanced a long way in the last decade to meet the extremely high emission standards of the EPA and CARB for diesel engines. What this advanced diesel tech means is that your engine has extremely high-operating fuel pressures and extremely tight tolerances for the fuel acceptable to the long term use of your engine.

What does this mean in a nutshell?

High operating fuel pressures and tight tolerances in the fuel rail mean dirt and water can destroy injectors and affect the operation of your fleet. These two contaminants (dirt and water) are the source of most other fuel-related problems and therefore your highest exposure to preventable maintenance cost. If you have experienced unexplained fuel filter spinning, failed injectors, and DPF maintenance that is more than normal, it may be fixable with Precision Fuel Management.

Precision Fuel Management is aggressive filtration at the fuel dispenser combined with PowerKleen Premium Diesel and a clean dry tank bottom that is sampled and tested regularly. If you want to look into cleaning up your bulk fuel, give Star Oil a call. Our first step is a complementary test of your fuel.

If you have an immediate concern about biological growth and long-term storage with your diesel, we recommend an alternative stopgap measure. Treat your fuel with Bioguard Plus 6 to kill the bugs growing in your diesel fuel.

Diesel Fuel Tank Cleaner

 

  • Diesel Fuel Is Often A Company’s Largest Expense. Unfortunately, there is very little control over its quality.
  • Fuel Quality Has Declined over the last 25 years…
  • Engine manufacturers have tightened the tolerances for fuel
  • Newer tier 4 engines starting from 2008 need cleaner fuel

 

“Over the last two decades, the cetane number and the API gravity, the basic measures of crude oil quality have declined.”

 

—Society of Automotive Engineers, (SAE) Bulletin 872243

 

Cetane number is actually a measure of a fuel’s ignition delay. This is the time period between the start of injection and start of combustion (ignition) of the fuel. In a particular diesel engine, higher cetane fuels will have shorter ignition delay periods than lower cetane fuels.

What is a typical API gravity for diesel fuel? The classic book “Petroleum Refinery Engineering” by W.L. Nelson (4th ed., McGraw-Hill, 1958) gives numbers ranging from about 25 to 40 (with “Grade 1-D” around 40 and “Grade 2-D” around 35). In a Web search using the keywords “diesel” and “API gravity” I found a couple of sites with specs for #2 diesel fuel; these had minimum values of 26 and 30 API gravity. So a reasonable guess would be that typical #2 diesel fuel would have an API gravity of about 35; I’ll let you plug that into the above formula to get the specific gravity.

The densities of petroleum products are traditionally (especially in the U.S.) expressed as “API Gravity” The API Gravity is related to the specific gravity by the equation: API = (141.5/SPGR) – 131.5, where the specific gravity is the density relative to that of water and everything is measured at a temperature of 60 degrees F.

The Future of Diesel Fuel

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 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, 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.

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.  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.

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.

Renewable Diesel Frequently Asked Questions (FAQ)

Every Question we have been asked about Renewable Diesel

What is renewable diesel?

Renewable diesel is a synthetic diesel fuel, known for it’s lower CO2 characteristics, typically seeing purity and real world performance response superior to petroleum diesel fuel.  Renewable diesel is a next generation hydrocarbon diesel biofuel made by either the Fischer-Tropsch or Hydrogenation processes.

Hydrogenated renewable diesel is made by taking fats, oils, and greases by use of a hydro-treater.  The biomass based oil or fat is cracked and reformed in the presence of hydrogen and  catalyst forming a hydrocarbon diesel molecule.

Fischer-Tropsch renewable diesel is used by converting any btu dense feedstock (wood waste, woody biomass, municipal garbage, coal, and an endless list of low value waste products into syngas, then converting this into a wax that is reformed into hydrocarbon diesel.

Is it true that Renewable Diesel reduces CO2 emissions by more than half?

It depends on the feedstock and processes that determine the fuel pathway.  But for the most part it is safe to presume that if you use a R99 Renewable Diesel product in Oregon that it will have a lower than 50CI which would cut the CO2 emissions in half versus an equivalent gallon of gasoline used.  Sometimes Renewable Diesel can be blended with fossil fuel diesel as well as biodiesel.  Star Oilco currently presumes 99% renewable diesel is the fuel being used when describing Renewable Diesel and “cutting emissions in half” as a claim, backed up by the scientific data associated with the Oregon Clean Fuels Program and its pathways.

According to the Oregon Clean Fuels Program list of pathways for Renewable Diesel approved to be sold in Oregon shows the lowest CO2 value to be 16.36 CI and the highest to be 65CI.  Most, nearly all, of the Renewable Diesel pathways in Oregon are below 50% reduction in CO2 emissions associated with the fuel.  You can see these by reviewing the downloadable spreadsheet of “Fuel Pathways – Carbon Intensity Values” available on the left hand side of the Oregon Clean Fuels Program website under the heading “Participating Facilities” as an easy sharable link is not available.

To learn more about this please see the Oregon Department of Environmental Quality’s Clean Fuels Program page where CO2 emission pathways are disclosed for renewable fuels distributed in Oregon.  The system used to measure CO2 emissions and reduction is a modified Oregon “GREET” model.  GREET stands for Greenhouse gas, Regulated Emissions, and Energy Use in Technology. The GREET scientific system to review CO2 emissions was developed by the US Department of Energy and similar systems are used by California and Washington in their Low Carbon Fuel Standards as well.

Is HVO or Hydrogenated Vegetable Oil the same as Renewable Diesel?

Yes.  HVO is either R100 or R99 renewable diesel. The reason you will hear the phrase HVO or Hydrogenated Vegetable Oil instaed of renewable diesel is that the regulations and various incentives for renewable diesel have restrictions.  If renewable diesel is used in stationary power generation it is treated differently for the various subsidies and incentives.  The regulations on fuels for vehicles and equipment differ compared to utility scale power generation.  For this reason the power generation industry will refer to renewable diesel as “HVO” to denote it’s end use.

Is Sustainable Aviation Fuel or “SAF” the same as Renewable Diesel?

No.  Sustainable Aviation Fuel or “SAF” is a Jet A specification or a Number 1 diesel fuel. A Number 1 diesel fuel can be mixed with Number 2 without impacting it’s specification requirements.  Number 1 though cannot be mixed with Number 2 diesel weights and stay in specification.  It is a lighter end than Number 2 diesel meaning it has a different specific gravity weight of the fuel.   So in short SAF can be used as Renewable Diesel but has a much higher standard to meet than is required for Renewable Diesel. Therefore the products are very different based on this need for quality assurance to meet the aviation jet fuel specification.

There is a huge demand for Sustainable Aviation Fuel and many of the current Renewable Diesel plants in operation are upgrading their technology to make SAF.  It is expected that in the hydrotreating processes to make renewable diesel and SAF, the Jet A fuel specification is a harder one to produce.  So as the refining of SAF increases we will expect to see subgrade SAF (product made to be SAF that does not meet the standard) be moved to the Renewable Diesel market.  We will not see Renewable Diesel being used in jets though.

Can Renewable Diesel be used as Heating Oil?

Yes.  Renewable Diesel is a synthetic hydrocarbon diesel fuel.  It can be used interchangeably with petroleum diesel products of similar grade. Heating Oil is typically number 2 diesel which is the same specification as Dyed R99 Renewable Diesel (or blends of Renewable Diesel with petroleum diesel).   Star Oilco now offers R99 Heating Oil delivered in the Portland metro region area of Oregon.

Most modern oil heat appliances use a Becket Burner.  For more on heating fuel compatibility with oil furnaces and oil burning appliance please see “Alternative Fuels and Becket Burners” for more information.

Why do people use renewable diesel over petroleum diesel?

Fleet managers operating R99 Renewable Diesel report a lower mechanical cost of operation using the fuel.  Beyond the immediate benefit of R99 cutting CO2 emissions by half or more, fleets experience performance benefits from the fuel.  The big savings are seen the the performance of Tier 4 Emission systems on modern diesel seeing far less wear of the Diesel Particulate Filter system as well as far fewer regenerations of the system.  Additionally Renewable Diesel is a very clean and dry diesel fuel improving the storage stability, field operation, and general predictability of the fuel’s performance.

How do I know Renewable Diesel is being sold at a retail location?

Renewable Diesel is a hydrocarbon diesel that meets the specification for petroleum diesel known as ASTM D975 specification.  This means currently R99 can be readily blended and sold with petroleum diesel without a disclosure.  The US Federal Trade Commission and local state Weights and Measures have rules for retail pump labeling.  Blend percentages of biomass based diesel must be labeled especially if being advertised.  As R99 Renewable Diesel has a higher value and is sought out by many consumers though usually it is disclosed.  The pump labeling for R99 Renewable Diesel typically looks like the below.

R99 Renewable Diesel fuel dispenser label

What is renewable diesel made of?

Renewable diesel can be made from a host of things, usually a low value waste product. The most common feedstock used currently is waste vegetable oil, wastes from animal rendering, and other biologically derived oils. Processes using bio-oils are following a Hydrogenation process to turn low value waste oils into high value diesel and jet fuel.

Chevron Renewable Energy Group and Diamond Green Diesel (Diamond Green is in a joint venture with Valero) are the largest producer of renewable diesel with their REG Ultra Clean Diesel product in the United States. Neste is the largest producer of renewable diesel internationally, with its “Neste My” product.  being the two largest producers of low CO2 bio-oil derived renewable diesel fuels.

Major petroleum refiners have also turned around existing petroleum refineries into Renewable Diesel Refineries to produce this in demand low CO2 fuel. HF Sinclair , Marathon, Phillips 66, and Montana Renewables. There are quite a few newer Renewable Diesel projects planned and in progress around the United States as well as in the Pacific Northwest.

Other refiners of renewable diesel (on a much smaller scale of production) are using a Fischer-Tropsch process with wood waste, sorted higher grade municipal garbage, and other high btu value carbon based waste products.  Many expect this to technology to be the future of all diesel and jet fuel refining turning refuse into fungible low carbon fuel.

What is renewable hydrocarbon diesel?

Renewable hydrocarbon diesel is a synthetic diesel fuel made from non-petroleum feedstocks like vegetable oil, animal fats, municipal waste, agricultural biomass, and woody biomass. It is characterized by having a low CO2 and renewable resource for its feedstock and is made without crude petroleum, coal, or natural gas as a direct feedstock input in the refining process.

How do they make renewable diesel?

Renewable diesel is made by several processes. If you are buying renewable diesel, it is probably from a Hydrogenation process used by Renewable Energy Group and Neste for their products. Other smaller volume producers are using a Fischer-Tropsch process or Fast Pyrolysis. Both processes involve taking energy dense molecules, cracking those molecules under heat and pressure, then reforming them in the presence of a catalyst and added hydrogen, which forms a renewable diesel molecule.

Is renewable diesel a lower carbon fuel compared to petroleum diesel?

Yes, to this point all renewable diesel made from renewable feedstocks have appeared to be a lower CO2 fuel compared to petroleum diesels. The California Air Research Board in particular has done research on this in depth.

The low CO2 lifecycle emissions of Renewable Diesel also is tracked closely and supervised by California’s Low Carbon Fuel Standard, Washington’s Low Carbon Fuel Standard, and Oregon’s Clean Fuels Program. The highest value markets for low CO2 fuels in the United States are California and Oregon, which both have mechanisms that track and price the CO2 intensity of diesel fuels as well as the sustainable lower CO2 substitutes and blend-stocks that can go in those diesels. They track, rate, and determine the carbon intensity of the fuels providing a neutral and scientifically defensible number for CO2 reduction.

Is renewable diesel available in Oregon?

Renewable diesel is readily available for delivery from Star Oilco throughout the Pacific Northwest via 10,000 gallon volumes of bulk delivery.   Star Oilco is also offering bulk delivery of any size and mobile onsite fueling service within 100 miles of the Portland, Oregon market.

Star Oilco has R99 Renewable Diesel available with a Star Oilco CFN Cardlock card in Portland, Oregon.

What is the difference between biodiesel and renewable diesel?

Biodiesel and renewable diesel are very different fuels made with very different processes. In a nutshell, biodiesel is made with a simple chemical reaction that turns vegetable and animal fats into fuel. Renewable diesel is made from far more complicated process where vegetable and animal fats (as well as other feedstocks) are cracked on a molecular level and built back into synthetic diesel fuel.

What is the difference between renewable diesel and Sustainable Aviation Fuel?

The difference between the fuels is the specific gravity and general specification for what the fuel is used for. Jet fuel, or Sustainable Aviation Fuel, and on-road diesel fuel are different fuels and therefore have different specifications. Renewable diesel is typically referring to a #2 diesel specification for on road diesel use.

Sustainable Aviation Fuel or “SAF” is typically referring to “Jet A” or “JP8” jet fuel specification for fuel. This is a #1 diesel range fuel with use and handling requirements that are far more stringent than for on-road or off-road diesel fuels. Renewable jet fuel can be used as a kerosene or #1 diesel fuel but renewable diesel cannot be used as a jet fuel.

Where do I buy renewable diesel in Oregon or Washington?

Renewable Diesel is currently available for bulk delivery and mobile onsite fueling. It will soon be offered at commercial cardlock in the Portland area. It is being sold as R99 and as Ultra Clean Diesel, which is a mixture of biodiesel, renewable diesel, and petroleum diesel.

What is R99?

R99 stands for 99% renewable diesel and 1% petroleum diesel.  Federal rules over alternative diesel fuels made fuels requires that manufacturers of non-petroleum derived diesel fuels must blend a minimum 1% petroleum with the fuel to generate a Renewable Industry Number or “RIN” under the US Federal Renewable Fuel Standard. Additionally there are other incentives that require a “blender of record” to receive these tax credits.

Is renewable diesel being made in Oregon?

As of Spring 2022, renewable diesel is not being manufactured in Oregon. There is a major projects underway, Next Renewable Fuels in Port Westward, Oregon.

What is renewable diesel made from?

Renewable diesel can be made from many energy dense carbon based material.  By volume of produced product sold in the United States, vegetable oils and animal fat-based wastes are the most common feedstock. Woody biomass, agricultural wastes, and sorted municipal wastes are also sources for renewable diesel production.

Is renewable diesel made from palm oil?

Palm oil can be used as a feedstock for renewable diesel. There are producers who use palm oil as a feedstock. In the United States, feedstocks and carbon intensity are tracked closely under both Oregon and California’s fuel programs.  You can determine if a supplier is using palm oil as a feedstock through these regulated pathways.

How much does renewable diesel cost?

This is a tough question to answer given there are several markets intersecting.  From the feedstocks to the market demand for the finished product as well as both California and Oregon’s Clean Fuel Standards which place a price on the CO2 intensity of the fuel which reduces the cost of the fuel if consumed in Oregon and California.

It has consistently been trending between the same cost and over $1 a gallon higher than petroleum diesel depending on the state, you buy renewable diesel in. In California, renewable diesel is very close to petroleum diesel depending on the value of CO2 credits for lower-carbon fuels. In Oregon, it has consistently been between $.05 to $.80 a gallon higher than diesel also depending on the value of CO2 abatement associated with the fuel and what these carbon credits are trading for.

When petroleum diesel costs are high Renewable Diesel tends to be more competitive with petroleum diesel.  When petroleum diesel is below $3 a gallon the cost of Renewable Diesel by comparison is usually higher unless CO2 credits are in higher than normal demand for Clean Fuels Program demands.

Can you mix petroleum diesel and renewable diesel?

Yes. Renewable diesel and petroleum diesel can be blended in any mixture without worry. They are drop-in substitutes for each other in your fleet’s use.  Renewable Diesel is a drop-in fuel. It is a hydrocarbon diesel that will work mixed with diesel or biodiesel blends of petroleum diesel.
