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 below $95/barrel, at a current price of $94.35/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 $94.35/barrel compared to $95.45/barrel last week and $74 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.

How Renewable Diesel Is Made 940 788 Star Oilco

How Renewable Diesel Is Made

Renewable diesel is a type of biofuel called biomass based diesel

How Renewable Diesel is Made

How is Renewable Diesel made?

Very similarly to fossil fuel diesel.

In the 1990’s the world started moving towards an ultra-low sulfur diesel fuel specification. Over decades we have arrived to where even marine fuels are running a lower sulfur fuel. The technology used to achieve this is hydrotreating the distilled crude oils.  By use of hydrocrackers, the molecules of petroleum crude oils are cracked and reformed into ultra-low sulfur diesel.  The use of hydrotreating diesel fuels has enabled the removal of sulfur and then enabling the use of emissions systems that not only reduce acid rain but also smog causing emissions like NOx.  This advanced petroleum refining chemistry technology is the forebearer to today’s renewable diesel technologies.  The technical chemistry of taking a feedstock, cracking the molecules and reforming them into a final product is where renewable diesel comes from.

Renewable diesel is a type of biofuel that is chemically similar to petroleum diesel and can be used in any diesel engine. It can be produced from various feedstocks, such as vegetable oils, animal fats, waste cooking oil, and algae. Renewable diesel can reduce greenhouse gas emissions and improve air quality compared to petroleum diesel⁵.  The inputs for renewable diesel are typically low value but high btu value feedstocks.   From virgin soy bean and canola oils to the lowest grade municipal wastes.  The modern chemistry of today’s petrochemical industry transforms them into the highly sought fuels. 

There are two processes making renewable diesel.  Hydrogenation and Fischer Tropsch Pyrolysis.

The most common way to produce renewable diesel is by hydrotreating, commonly referred to as hydrocracking, which involves reacting the feedstock with hydrogen under high temperature and pressure in the presence of a catalyst.  Renewable diesel made with this process is often called Hydogenated Vegetable Oil (HVO). HVO and Renewable Diesel are the same fuel.  Utility scale power generation often will refer to HVO as their technical term for this low CO2 biofuel.

How HVO is made is extremely similar to crude fossil fuel.  The investments to do it also cost billions of dollars similar to the costs of petroleum refining.  Imagine a vegetable or animal fat being put under pressure, the molecules are cracked into smaller chain molecules and as this stream of feedstock is passed in the presence of a catalyst as hydrogen is added it forms hydrocarbon molecules like diesel, jet fuel, and propane.   This process removes oxygen, sulfur, nitrogen, and other impurities from the feedstock and converts it into hydrocarbons that are similar to those in petroleum diesel⁴⁵. Hydro processing is also used in petroleum refineries to upgrade crude oil into various fuels, such as renewable diesel. 

Other ways to produce renewable diesel include pyrolysis, usually using a Fischer Tropsch process.  Pyrolysis is usually made from high energy content dry garbage.  Think wood waste, plastics, tires, and other high Btu content waste streams.  These garbage feedstocks are transformed into hydrocarbons with a process of heating the feedstock in the absence of oxygen to produce a liquid bio-oil that can be further upgraded into renewable diesel; gasification, which involves converting the feedstock into a mixture of carbon monoxide and hydrogen (syngas) that can be synthesized into renewable diesel; and biochemical and thermochemical technologies, which involve using enzymes, microorganisms, or catalysts to convert the feedstock into renewable diesel⁴. 

According to the U.S. Energy Information Administration (EIA), U.S. production capacity for renewable diesel could increase significantly through 2030, based on several announced and developing projects. This growth is driven by higher state and federal targets for renewable fuel, favorable tax credits, and the conversion of existing petroleum refineries into renewable diesel refineries². As of the end of 2020, U.S. renewable diesel production capacity totaled nearly 0.6 billion gallons per year (gal/y), or 38,000 barrels per day (b/d). Several projects currently under construction or completed can jump this capacity up billions of gallons.  could increase this capacity by 2.4 billion gal/y; proposed and announced projects would add another 1.8 billion gal/y by 2024. If all projects come online as intended, U.S. renewable diesel production would total 5.1 billion gal/y (330,000 b/d) by the end of 2024². 

Globally, over 1.45 billion gallons of renewable diesel are produced annually and are forecasted to grow up to 3.34 billion gallons in 2024. Neste, a Finland based petroleum refining company, is currently dominating the production of renewable diesel¹. Other major producers in the United States include Chevron, BP, Seaboard Energy, Phillips 66, HF Sinclair, Montana Renewables, Marathon, and Diamond Green Diesel¹.

What Are Our Options for Alternative Fuels? 1024 578 Star Oilco

What Are Our Options for Alternative Fuels?

What are our options for alternative fuel?

Biofuels are eco-friendly fuel choices because they are made from renewable resources and produce fewer emissions than fossil fuels. Biofuels and biodiesel can also be used to improve air quality. They also allow us to reduce the dependence we have on using fossil fuels. 

Biofuels are liquid fuels produced from biomass, which is organic matter such as plants, algae, and agricultural waste. Biofuels can be used to power vehicles, generate electricity, and heat homes and businessesBiofuels are renewable and can reduce emissions of greenhouse gases. They provide an alternative to fossil fuels and help to conserve natural resources. Reducing the emissions of greenhouse gases is an important factor in helping to combat climate change. Biofuels have the potential to be a significant part of the solution. Biofuels can reduce emissions of greenhouse gases by replacing fossil fuels, which are made from non-renewable sources. Using biofuels instead of fossil fuels can also help to reduce air pollution. 

Some common types of biofuels include: 

Ethanol

Ethanol is a type of alcohol that is made from fermented corn, sugarcane, and other crops. It is blended with gasoline to create E85, a fuel that can be used in flexible-fuel vehiclesThis type of fuel is cheaper than regular gasoline, and it is more environmentally friendly. It is also safer to store and transport than other types of fuel. The benefits of using ethanol fuel include reduced emissions of carbon dioxide, improved air quality, and increased energy security. It is also renewable and biodegradable, making it a more sustainable fuel choice. Additionally, the production and use of ethanol fuel can create jobs and support local economies. 

 

Biodiesel

Biodiesel is a type of diesel fuel that is made from vegetable oils, animal fats, and waste grease. It can be used in unmodified diesel engines as a drop-in solution. It is a renewable fuel and emits less carbon dioxide than petroleum-based diesel. Biodiesel is also less toxic and it’s biodegradable. The benefits of biodiesel include reduced emissions of carbon dioxide, sulfur dioxide, carbon monoxide, and unburned hydrocarbons; improved combustion efficiency and power output; improved lubricity; and improved fuel economy. Additionally, biodiesel is biodegradable and has a lower energy content than petroleum-based diesel, making it safer to handle and transport in the Portland, Oregon metro area as well as Vancouver, Washington. 

Biodiesel can be used in a variety of applications, including transportation, heating and electricity. Biodiesel is used in transportation to power diesel engines in cars, trucks, buses, and other vehicles. Biodiesel can also be used to heat homes and businesses. Biodiesel also can generate electricity in power plants.  

Biodiesel is a promising alternative to petroleum diesel, and its use is growing around the world. The United States is the world’s largest producer of biodiesel. 

Algae-based biofuels

Algae-based biofuels are a new type of biofuel that is made from algae. Algae are a rapidly renewable resource that can be grown in a variety of environments. Algae is a group of photosynthetic organisms that grow in water. Algae have the potential to produce significantly more oil than traditional biofuel crops, such as corn and soybeans, and they can be grown on non-arable land, such as saltwater or wastewater. This makes algae an attractive potential source of renewable fuel. 

When algae are grown in the right conditions, they can produce up to 77% oil, which can be converted into biodiesel, renewable diesel, or other biofuels such as ethanol, butanol and jet fuel. Algae-based biofuels have the potential to significantly reduce greenhouse gas emissions from transportation, electricity generation, and other industries. However, there are still challenges that need to be overcome before algae-based biofuels can be commercially viable. These challenges include scalable production, costs, efficient harvesting and efficient processing to extract the oil. There is a lot of research and development underway to overcome these challenges and with continued investment, algae-based biofuels have the potential to become a major source of renewable fuel in the future. 

 

Hydrogen

Hydrogen is a versatile energy carrier that has the potential to play a significant role in the transition to a clean energy future. It is the most abundant element in the universe and can be produced from a variety of sources, including natural gas, biomass, and renewable electricity. When used in a fuel cell, hydrogen produces only water and heat, making it a clean and efficient fuel source. 

Using hydrogen as a fuel provides clean burning, a high energy density, efficiency, among many other benefits. Hydrogen doesn’t produce any emissions of harmful pollutants which makes it an attractive option as a fossil fuel alternative. Hydrogen’s high energy density means that a relatively small amount of hydrogen can provide a lot of energy. Using hydrogen fuel cells to generate electricity are 2-3 times more efficient than internal combustion engines. It can also be used in a wide range of applications, including transportation, electricity generation as well as industrial processes.  

Some of the challenges we face with hydrogen as a fuel are its current methods of production. They are not always as clean or sustainable currently. Storing hydrogen, being a gas, requires specialized storage tanks. The infrastructure for transporting and distributing hydrogen is not yet fully developed.  

Overall, there is a growing interest in using hydrogen as a fuel source with very promising results and possibilities in our future. Governments and businesses all over the world have been investing in research and development to figure out solutions to these challenges in order to make hydrogen a more viable energy source.  

Renewable Diesel

Renewable diesel can also be known as hydro-treated vegetable oil (HVO) or green diesel, and is a type of biofuel that is chemically identical to petroleum diesel. It is produced from a variety of feedstocks, including vegetable oils, animal fats, and waste oils. Renewable diesel can be used in any diesel engine without modification, and it offers a number of environmental benefits over petroleum diesel, including: 

 

Reduced greenhouse gas emissions 

Renewable diesel (R99) reduces greenhouse gas emissions by up to 90% compared to petroleum diesel. R99 being cleaner and more efficient, makes it an attractive option for many transportation companies. 

 

Improved air quality 

Renewable diesel produces fewer harmful pollutants, such as particulate matter and sulfur oxides, than petroleum diesel. Additionally, renewable diesel is lower in carbon than petroleum diesel, making it a more sustainable option for transportation. Renewable diesel is also more efficient, reducing the amount of energy needed to produce the same amount of fuel. 

 

Biodegradability  

Renewable diesel is biodegradable, meaning that it breaks down naturally in the environment.  This helps to reduce the amount of harmful pollutants in the environment. Renewable diesel also reduces emissions of carbon dioxide, a major contributor to climate change. 

Renewable diesel is a promising alternative to petroleum diesel, and its use is growing around the world. The United States is the world’s largest producer of renewable diesel, and the European Union has a mandate to use 10% renewable diesel by 2030.  

Even more of the benefits of using renewable diesel:  

The use of renewable diesel helps reduce our dependence on fossil fuels since it is a renewable fuel.  

The local economy can be supported by renewable diesel, which is often produced from local crops.  

A number of sectors, including agriculture, manufacturing, and transportation, create jobs in the renewable diesel industry.  

Ultimately, renewable diesel is a clean and sustainable fuel that offers environmental and economic benefits. Around the world, its use is growing as an alternative to petroleum diesel. Renewable diesel helps to reduce air pollution, reduce greenhouse gas emissions, and reduce dependence on foreign oil. It is also a renewable and sustainable fuel source that can be used to produce electricity. As such, renewable diesel is an important option for reducing carbon emissions and improving sustainability overall. 

When we look at the variety of renewable and biofuel opportunities, there are a variety of ways that we can reduce our carbon footprint today without any modifications to our current engines. However, long term, we have opportunities that we can explore for where we believe that our future is going and the solutions that can allow for an even greater impact to our Pacific Northwest carbon footprint and reducing greenhouse gas emissions. Among all of the renewable resources, we can reduce air pollution, increase economic benefits and create a more sustainable future for the Portland, OR and Vancouver, WA metro areas. As technology continues to improve and the production of biofuels and biodiesel becomes more efficient, these fuels are likely to become more affordable and widely available.

What Is Portland’s Renewable Fuel Standard?

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

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

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

Choose Star Oilco As Your Preferred Fuel Delivery Company

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

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

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

Portlands Renewable Fuel Standard Requirements

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

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

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

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

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

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

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

  • On-Site Fleet Fueling
  • Wet Hose Fueling

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

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

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

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

Biofuel Minimum Content Requirements for Wholesale Purchaser-Consumers

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

Selecting a compliance option for Wholesale Purchaser-Consumers

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

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

Record Keeping Requirements for Wholesale Purchaser-Consumers

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

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

Clear Premium Non-Ethanol Gasoline 683 1024 Star Oilco

Clear Premium Non-Ethanol Gasoline

Do you need Non-Ethanol Gasoline delivered in the Portland, Oregon area?

If you are looking for Non-Ethanol Premium Gasoline delivered to your bulk tank or available at a Commercial Cardlock, Star Oilco has your needs covered in the Pacific Northwest.

Premium Unleaded without Ethanol in the Gasoline

Nonoxy Premium is the fuel you want in a gasoline tank if you are storing equipment with a full tank of fuel.

Premium gasoline without any ethanol blended into it goes by several names.  Clear premium unleaded, Non-Oxy (non-oxygenated) premium, nonethanol gasoline, or Clear 91 Octane are a few of the terms used.  Regardless of what it is called, getting gasoline without ethanol in the Portland, Oregon area requires buying a premium rated gasoline.

Clear Gasoline Premium bulk tank delivery

Why is the only ethanol free gasoline in Oregon and Washington premium grade of 92 octane?

This is because of several laws in Oregon as well as Washington that require the blending of 10% ethanol with all gasoline with the exception of premium grades for small engines, classic cars, aviation uses, and other type specification needs.

With the blend requirements for 10% ethanol this changed the way gasoline was supplied in the Pacific Northwest.  This was caused by the octane ratings of gasoline.  Regular gasoline is a 87 octane rating.  E98 ethanol has a 107 octane rating. With this blend requirement, the gasoline changed to account for the high octane of ethanol.  So refiners and sellers of gasoline began to use what the industry calls a “sub-octane” gasoline at 85 octane because the guaranteed blend of 10% ethanol would boost the octane rating back up to 87 octane.

This is usually where people ask: “Why does this effect premium unleaded as well, and why the heck is clear premium so expensive?”

There are three reasons nonoxygenated gas costs more:

1- Ethanol is a lower cost fuel than gasoline, so less ethanol means a slight higher price of the fuel.

2- Fewer terminals carry a non-ethanol option for Premium unleaded reducing options for customers demanding the fuel and therefore higher prices.

3- CO2 regulations have raised the cost of fuels without biofuel blends in them as well.

REASON 1

The reason why is for several decades before the 10% ethanol blend mandate, the industry has been upgrading retail gas stations, cardlocks, and truckstops to blend regular gasoline and premium gasoline to the midgrade gasoline at the island. With a 10% ethanol blend mandate for regular unleaded and midgrade this required any and all retailers with blending pumps to use E10 (10% ethanol) premium to be legal with their midgrade product sold.  This also means that a non-ethanol premium pump requires a stand alone pump, line set up, and infrastructure need.

REASON 2

The blend mandates for gasoline caused all of the major branded gas station chains to move to a defacto 10% blend at the terminal level reducing availability of non-ethanol or “Clear” premium gasolines. With far fewer petroleum terminals, brokers, refiners, and other upstream wholesale dealers of gasoline exiting the non-ethanol gasoline market due to far lower volumes of it, the price went up.  This also means that there is far less volume of ethanol free premium unleaded being sold at the wholesale level. Reducing the volume of sales of a single fuel grade raises the cost risk in a volatile commodity market like gasoline.

REASON 3

Recently the entire western coastal states (Oregon, Washington, and California) passed laws around CO2 emissions and liquid fuels like gasoline.  This means that there is a cost for fossil fuels over biofuels which prices into the gallon of fuel.  The less biofuel the higher the CO2 cost for those buying it. Add to that the western states have Cap and Invest rules which put a total limit on volumes of fossil fuels.  These “Cap at the Rack” charges for fossil fuel have been as high as a full $1 for a gallon of fossil fuel in past years.  Cap at the Rack charges on fossil fuel gasoline is usually in the $.40 a gallon added cost range of the price you pay.

If Clear Premium Gas is so expensive why do people still use it?

It is the optimal fuel for small engines that have a habit of being stored for long periods of time without use.  Nonethanol fuel stores stable for a longer time and has a better cold start performance than an E10 gasoline fuel that has sat for over a year.  Add to that it also does not absorb water or impact plastic/rubber/elastomer seals in equipment.  That is why people prefer it.  Sure, the limited availability of terminals carrying this product makes it a specialty in Oregon and Washington.  But the added cost is worth it for sensitive low tolerance engines or for vehicles with long periods of storage between uses.

What is biodiesel? Is it the same as raw vegetable oil?

Biodiesel is a cleaner burning diesel fuel made from vegetable oil. Simply stated, a biodiesel molecule is a                                                              vegetable oil molecule with the glycerol removed. Chemically, biodiesel is defined as a mono-alkyl ester of                                                           vegetable oil.

Biodiesel is NOT the same as raw vegetable oil or straight vegetable oil (SVO). Diesel engines actually can                                                             operate on straight vegetable oil (SVO) as a fuel. In fact, Rudolf Diesel’s first compression ignition (Diesel)                                                            engine introduced in 1895 used peanut oil as its fuel. Modern diesel equipment, however, requires some                                                          modification to burn straight vegetable oil, and it is yet unclear the effects of straight vegetable oil on diesel                                                         engine performance and longevity.

Will biodiesel void my engine warranty?

According to the National Renewable Energy Laboratory, “Original Engine Manufactures (OEM) provide a material and workmanship warranty on their products. Such warranties do not cover damage caused by external conditions, such as fuel. Thus, if an engine using biodiesel experiences a failure unrelated to the biodiesel use, it MUST be covered by the OEM’s warranty. Federal law prohibits the voiding of a warranty just because biodiesel was used – it has to be the cause of the failure. If an engine experiences a failure caused by biodiesel (or any other external condition, such as bad diesel fuel), it will not be covered by the OEM’s warranty.”

Star Oilco distributes only commercially produced biodiesel that meets ASTM D6751-03 specification – a demanding fuel testing regimen that guarantees the fuel will perform properly in your engine.

Biodiesel is considered an additive in blends less than 6% (B5). Petroleum diesel with 5% biodiesel added still meets ASTM specifications for #2 petroleum diesel fuel. The National Renewable Energy Laboratory and numerous states and federal fleets, including all branches of the U.S. Military, have performed more than 40 million miles of road testing on B20. The results of which have only been positive.

Fleets such as Yellowstone National Park and the City of Berkeley (CA) Solid Waste Management Division have had great success running diesel vehicles on pur biodiesel (B100).

Does biodiesel cost more than petroleum diesel?

Yes. The current retail price for on road B99 is $3.29 per gallon. Our customers pay a premium for biodiesel to support domestic energy sources and because of environmental concerns. Many biodiesel users experience a lower maintenance cost when they use biodiesel.

Can I use Oregon produced biodiesel?

Yes! In fact, the biodiesel you purchase through Star Oilco is produced right here in Oregon! Sequential Biofuels opened their first plant in Salem, OR in July 2005. This plant will produce 1 million gallons of biodiesel annually from waste vegetable oil. Oil sources include the Salem Kettle Chips plant. Country singer Willie Nelson is an investor in the effort.

Does biodiesel provide similar miles per gallon, torque, and horsepower?

In terms of energy contained in the fuel, a gallon of biodiesel contains slightly less energy than a gallon of petroleum diesel. For example, B20 tends to reduce fuel economy by approximately 1%. B20 users rarely report changes in torque or power. With B100, torque, power and fuel economy can be reduced by approximately 8%. However, the increased lubricity of biodiesel may help to counteract this energy difference. Some drivers report better performance with biodiesel, but most do not notice any difference.

Can I switch back and forth between diesel and biodiesel?

Yes! Biodiesel is the ultimate flexible fuel, so you can switch back and forth between biodiesel and petroleum diesel whenever necessary. Also, you can blend biodiesel with petroleum diesel in any percentage.

Is biodiesel safe to handle?

Yes! Biodiesel is ten times less toxic than table salt and biodegrades faster than sugar. The EPA has tested biodiesel’s health effects extensively and has classified it as a non-toxic substance that poses absolutely no threat to human health. Biodiesel is such a clean fuel that it is used to remediate petroleum spills in water.

Can I use biodiesel in an oil furnace (to heat my home)?

Yes! Biodiesel can be used in any diesel application. Oil #2 is the primary heating oil sold in the U.S. It is essentially the same as the diesel sold at gas stations, but contains much more of the pollutant sulfur. Sulfur contributes to acid rain formation, as well as the creation of nitrous oxides and particulate matter, both of which have serious air quality and human health impacts.

Biodiesel is just as warm as regular heating oil, but will help keep both the furnace and the air cleaner. It reduces the oily smell of the liquid fuel and makes the exhaust coming from the chimney smell better – a little like French fries. Pure biodiesel is biodegradable, and it is far less toxic than diesel. With a higher flash point, it is also less of a fire hazard. Biodiesel reduces emissions of cancer-causing compounds by up to 50%, and emissions of nitrogen oxides, particulate matter and hydrocarbons by approximately 20%.

Do I have to modify my furnace to use biodiesel?

No. B20 requires no modification to your heating system. However, biodiesel is a solvent, and will actually clean heating oil tanks and all fuel-wetted parts of a furnace. Because of this, users may experience clogging of the furnace fuel filter early on. Fuel filters are cheap and easy to replace, and the problem will end once the system is cleaned out.

If your heating oil tank is outside and/or underground,Star Oilco will only deliver B20 home heating oil. If your heating oil tank is located inside and above ground, Star Oilco will deliver B20 or B99.

Can biodiesel replace petroleum diesel?

For most of the 20th century, petroleum diesel has been consumed as though it would last forever. Experts disagree about how much petroleum is left and how long it will last. They do agree, however, that less new oil will be found and that prices will increase. Because biodiesel is “home-grown”, it provides energy security. Biodiesel can be produced on a yearly cycle, instead of a 10-million-year-cycle. While we can not displace all petroleum with renewable fuels, it is one important piece of reducing our dependence on foreign oil.

Fuel Market News

Fuel prices dropped this past week as tensions and conflict in Iran remained stagnant. The stagnation did not last as Iran announced negotiations did not continue, and they will return to a full blockade of the Strait of Hormuz. Upon this announcement, the US reinitiated its ground striking campaign in Iran with multiple strikes on Saturday & Sunday. The US reportedly struck military bases, radars, and drone sites in Tehran. The re-engagement of the conflict between Iran & The US has continued to choke the marine traffic throughout the Straight of Hormuz. Last week, only 36 ships passed through the waterway compared to 130/day before the conflict started.

Crude oil prices are skyrocketing on the heels of news over the weekend of the re-engaged military conflict in Iran. Fuel prices are expected to take a steep climb throughout this week as the conflict continues with no end in sight. The Trump Admin has proposed waiving the federal gas/diesel tax until September 2026. An act that would require approval by Congress. This proposal has signaled to many that the conflict in Iran will not be over anytime soon. This week, we will likely see crude oil prices back over $100/barrel.

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 $95/barrel, at a current price of  $95.45/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 $95.45/barrel compared to $98.19/barrel last week and $75 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.

Fuel Market News

Fuel prices were mostly stagnant this past week, with only a $0.02/gal variance on both the wholesale rack market and the retail market. Crude Oil prices are currently hovering around $110/barrel. President Trump has once again delayed planned strikes on Iran while also extending Russian sanction waivers for “vulnerable countries”. This allows given countries to buy Russian oil and refined products until June 17th.

The continued hostility between the US & Iran along with higher crude prices has cost US consumers an estimated $45 billion since the beginning of the war, with no end in sight. The conflict continues to draw bipartisan disapproval as goals and timelines of the war remain extremely murky. A global oil shortage is continuing to grow with an estimated 1 billion barrels in production lost by the end of May. The IEA has warned that demand for oil will exceed supply in 2026 with a daily loss of production exceeding 3.9 million barrels. Analysts across the globe are factoring a prolonged oil shortage and its lasting effects on supply and demand into the 3rd quarter of 2026.
