Fuel Market News

Fuel prices were mostly stagnant this week, with fuel prices only moving a few cents while crude oil still hovered just above $70/barrel. The peace agreement between the US & Iran has continued to be shaky, with the US striking Iran on the 27th of June after Trump preached of peace and a “deal being done” on Truth Social. The continued murkiness has led the US public to begin to question what is actually going on and why this “3-week” operation is now entering its fifth month of conflict. The conflict has cost US consumers approximately $45 billion due to higher fuel and oil prices and inflation across the board.

Retail gas prices in Portland are just under $5/gal at a current average of around $4.85/gal, while the Seattle area is at $5.48/gal.  Retail diesel prices in Portland are just under $6/gal at a current average of $5.87/gal, while the Seattle area is over $6.25/gal. Crude oil prices have continued to tumble upon the renewed talks of a peace agreement between the U.S & Iran. Many doubt the legitimacy of peace agreements with continued military action and missile strikes occurring over weekends on more than one occasion. Much remains unclear about the current situation in Iran to the general public in the U.S.

Important Note: Per the City Of Portland, “Distributors in the City of Portland are required to meet the minimum biofuel content requirements for all fuel they distribute beginning on May 15, 2024. All diesel fuel distributed to retail stations, non-retail dealers, or wholesale purchaser-consumers must include a minimum of 15% biofuel content, from either renewable diesel or biodiesel. This requirement increases to 50% on May 15, 2026, and 99% on May 15, 2030”.

Crude oil is hovering just above $70/barrel, at a current price of $70.11/barrel.

Crude oil is the main ingredient for gasoline and diesel. Per AAA, on average about 50% of what you pay at the pump is the price of crude oil, breaking down as 25% refining, 11% distribution & marketing, and 14% taxes – a helpful breakdown for consumers wondering why they are paying the prices that they pay. Crude Oil is currently trading at $71.88/barrel compared to $70.11/barrel last week and $76 a year ago.

It’s essential to recognize that fuel prices result from a complex interplay of the factors mentioned above and other regional factors. Additionally, prices may vary by specific regions within Oregon and Washington.

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.

Fuel Market News

Fuel prices dropped for the second straight week rolling into July. As peace negotiations continue between the US & Iran, the Strait of Hormuz has been partially opened and traffic is flowing through the area slowly. Although the conflict is still in arms with much left unclear, the markets have responded positively to the peace negotiations and current ceasefire between the US and Iran. Crude oil prices have dropped over $15/barrel over the past 2 weeks since the announcement of a peace treaty between the US & Iran. The past few months have taught us to expect the unexpected regarding the conflict in the Middle East, so there is still a lot of skepticism surrounding the legitimacy of a long-lasting peace agreement and true ending to the war between the US & Iran.

Retail gas prices in Portland are just under $5/gal at a current average of around $4.95/gal, while the Seattle area is at $5.48/gal.  Retail diesel prices in Portland are just under $6/gal at a current average of $5.85/gal, while the Seattle area is over $6.31/gal. Fuel prices have dropped over $0.30/gal since the US/Iran peace announcement. With many wondering if this agreement will last into the future, the market has responded positively for the time being.

Biofuels Industry Exceeds EPA Expectations 1024 618 Star Oilco

Biofuels Industry Exceeds EPA Expectations

Biofuels Industry Surpasses Expectations with a Massive Production Rise

Based on the data, biomass-based diesel production has increased massively in the United States, including biodiesel, renewable diesel, sustainable aviation fuel, and heating oil. Biomass-based diesel was expected to produce 4 billion gallons in 2023. Biofuel production and use increased by one billion gallons from last year to this year, which is a big jump. As a result of this achievement, a breakthrough has been achieved. The industry has surpassed what the EPA once thought was impossible with the development of advanced biofuels derived from sustainable sources.

So the real question is, what if we don’t choose biodiesel or renewable diesel over petroleum diesel for our diesel engines?

Biofuel production from plant oils and renewable crops for clean diesel alternatives
  • Biofuel production soared in 2023, exceeding EPA goals.

  • US biomass-based diesel production (biodiesel, renewable diesel, SAF, heating oil) reached 4 billion gallons.

  • Biofuel production and use jumped by 1 billion gallons year-over-year.

Clean Fuel Industry Beats Regulations in Decarbonization Push

While the Clean Fuels Alliance urged the EPA to set even more ambitious goals, like increasing biomass-based diesel production by 500 million gallons a year over the next three years, the EPA has taken a more conservative approach. Regulations aren’t keeping up with the industry, but it’s not waiting for them. Clean fuels are becoming more accessible and heavy-duty transportation fuels used by aviation and maritime are getting decarbonized. The industry has shown its ability to grow quickly and sustainably thanks to this collaborative effort.

  • Clean Fuels Alliance pushed for aggressive EPA goals: 500 million gallons annual increase in biomass-based diesel production for 3 years.

  • EPA’s finalized standards took a cautious approach.

  • Oil and gas producers, refiners, distributors, and retailers don’t have to wait for strict regulations to act (producers, refiners, distributors, retailers).
  • Industry collaboration demonstrates the potential for rapid, sustainable growth.

Decarbonization concept with CO2 reduction icons over a globe in green grass symbolizing clean energy

Despite this year’s achievements, the Clean Fuels Alliance remains focused on the future. There’s so much potential in sustainable biofuels that we think the EPA hasn’t tapped into yet. Supporting biodiesel, renewable diesel, and SAF production can help achieve clean energy progress.

In reality, why wouldn’t we make the switch to lower our carbon emissions today?

Save money with a commercial fuel card 1024 544 Star Oilco

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.

How we approach buying commercial fuel with a gas card.  There are only three parts of your fuel cost.  Let us help you understand what you pay for fuel:

Renewable Diesel or Biodiesel: Which Is Better? 683 1024 Star Oilco

Renewable Diesel or Biodiesel: Which Is Better?

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. 

Fuel-Pathways-Carbon-Intensity-Values

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.

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.

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.

In most cases, it’s water and dirt in the fuel leading to further degradation over time. If gone unchecked it will lead to mechanical failures in your fleet.

 

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.

Portland Renewable Fuel Standard Explained

Did you hear about the time Portland banned fossil fuel diesel?

Portland is making a big move to provide cleaner air and reduce greenhouse gas emissions. Portland has implemented what’s called the Renewable Fuel Standard (RFS) beginning  its first phase on May 15th, 2024. The RFS policy in Portland mandates that there has to be an increase of use of low-carbon biofuels in diesel within city limits of Portland. This is part of the ultimate Climate Emergency plan. This RFS mandate was first implemented in 2006 as a B5 (5%) Biodiesel blend mandate with the goal of mandating a 20% blend. The RFS is the first of its kind not only in Oregon but in the entire United States. Portland’s reputation as a leader in environmental sustainability efforts continues. 

Portland’s Phases To Implement Almost 100% Renewable Diesel

What makes Portland’s mandate unique is the requirement that the biofuels have a CO2 value so low it bars most American made biodiesels. The blending requirement starts at 15% in 2024, and then it will steadily increase to 50% by 2026 and will reach 99% by 2030. This schedule demonstrates how Portland’s low-carbon ambition is present to transition away from fossil fuels and promote alternative energy sources.

This policy is expected to reduce air pollution and carbon emissions. It will also create new markets for biofuels, which will lead to increased economic opportunities. This will ultimately help the city become a more sustainable and environmentally friendly place to live as Portland has taken the lead in striving for sustainability over the years.

The policy will also help create jobs in the biofuel industry and provide opportunities for businesses to switch to renewable energy sources. It will also help reduce the city’s dependence on fossil fuels and protect the environment for future generations.

Focus on Lower-Emission Biofuels

Uniquely, Portland’s RFS goes beyond just the biofuel blend. It also sets a strict carbon intensity (CI) standard for the biofuels themselves. This ensures the biodiesels used have a significantly lower carbon footprint compared to traditional options. Biodiesels produced domestically often fall short of this CI requirement, prompting many suppliers to look to renewable diesel sources. This focus on biofuels with a lower lifecycle carbon footprint makes Portland’s RFS even more impactful in reducing greenhouse gas emissions.

Exemptions and Implementation Details

The initial phase of the RFS targets on-road diesel sales. This applies to diesel purchased at gas stations, by mobile fueling companies, and for use in large stationary tanks. However, the long-term goal includes all diesel use within the city. Some temporary exemptions apply to off-road diesel uses such as heating oil, generator fuel, aircraft fuels, watercraft fuels, and other dyed fuel users. One local truck stop, Jubitz Truckstop, was granted a temporary exemption. This is likely due to concerns about disrupting critical transportation operations. Daimler (the manufacturer of Freightliner and Western Star trucks) has a research facility in Portland. Daimler was also granted an exemption to meet their specific fuel needs for testing purposes. 

The RFS enforces compliance through fuel sampling and requires documentation proving the fuel meets the minimum biofuel content and CI standards. Businesses that purchase diesel need to be able to show their compliance through bills of lading (BOLs) or similar records from their fuel provider, like Star Oilco. If a business does not comply and provide this documentation, it can result in pretty hefty fines. First offenses can be a fine of $10,000 per day. Repeat offenders will end up facing even bigger penalties of up to $15,000 per day. These fines can really show the impact of how serious Portland is taking this initiative. 

Impact on Businesses and Consumers

While residential consumers who don’t purchase diesel directly are not directly impacted, businesses purchasing diesel, especially in bulk, will need to adapt to the new regulations. This may involve acquiring documentation from fuel suppliers or entering into contracts guaranteeing compliant fuel blends. Wholesale fuel distributors, who sometimes purchase from multiple vendors and blend fuel mid-route, may face additional challenges in tracking the biofuel content and CI of their product. However, as the program matures, the industry is expected to adapt and streamline these compliance procedures.

A Step Forward for Cleaner Transportation

Portland’s ambitious RFS sets a new expectation for sustainable transportation. Promoting low-carbon biofuels allows Portland to aim to significantly reduce its reliance on fossil fuels and be able to contribute to cleaner air for its residents. The RFS program will be able to serve as a model for other cities that are looking at implementing similar initiatives. Great job Portland for paving the way to a sustainable future for other cities! Although challenges will remain, as businesses adapt to this new norm, Portland’s RFS represents a significant step forward in creating a more sustainable transportation sector.

The RFS program is an important step in the fight towards sustainability and lower carbon fuels. It sends a clear message that cities are willing to take action to reduce emissions and protect the environment. We anticipate that other cities will follow Portland’s lead and create similar initiatives. This will have a significant impact in reducing emissions and helping to protect the environment.

It is a positive step towards a more sustainable future. Alternative fuels have become more and more readily available. Investing in alternative fuels and reducing carbon emissions is essential for protecting the planet for future generations. Governments should prioritize investing in renewable energy sources and incentivize communities to switch to alternative fuel solutions.

Thank you for choosing Star Oilco as your preferred fuel provider in Portland and Vancouver, Washington. Give us a call to discuss how the RFS mandate can affect your business and one of our team members would be happy to discuss this with you.

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.
