We often receive questions about backup generators, backup water pumps, and other emergency equipment. Fueling these critical pieces of equipment is a special kind of fueling service but we’re here to answer all your questions. We also encourage you to call with questions about generator fuel.  If you have questions about your building’s back up diesel generator’s fuel quality in the Portland, Oregon area we will sample and test your fuel at not cost with if you have an account with Star Oilco.

Generator Fuel is a specially treated oxidative stabalized off-road fuel designed to store for years.

Fuel for a backup generator is a specialized product. Besides the fuel, the service itself takes a vendor who understands your needs and can keep you up and running in an emergency.

Generators take off-road diesel, of course, but you want an ultra low sulfur diesel to ensure it works with modern emission systems. Some companies may deliver a higher sulfur heating oil product that looks the same but can foul the emission systems of your equipment.

Backup Generator Fuel in Portland

Beyond just the service provided by a truck and driver, you also want a vendor who offers a fuel stabilizer and biocide for the special long term storage needs of your backup generator. Star Oilco recommends you add a biocide and long term storage stabilizer to your fuel to ensure it is good whenever you need it. We use Valvtect Bioguard Plus 6 for generators, emergency water pumps, backup boiler fuel, and other long term storage purposes. This product kills any existing biological growth and stabilizes your fresh diesel fuel for long term storage. Make sure your diesel is ready the next time you need backup power.

Bio-diesel and Feed-stock samples at REG
What Types of Feedstock Can Be Used To Make Biodiesel? 700 525 Star Oilco

What Types of Feedstock Can Be Used To Make Biodiesel?

               What Types Of Feedstock Can Be Used To Make Biodiesel?

        To answer what feedstocks can be used to make biodiesel we need to first answer:  What is Biodiesel?

Biodiesel is created through a process called transesterification.  Transecterification is when an alcohol such as methanol or ethanol is added to an oil or fat.  This creates methyl esters and glycerin.  Methyl esters is the scientific name of Biodiesel.  Because biodiesel needs a fat or an oil to start with, this fuel can can be created with any number of feedstocks.  If you would like to learn more about Biodiesel check out this for more questions about biodiesel.

According to the U.S. Office of Energy Efficiency & Renewable Energy:

“A feedstock is defined as any renewable, biological material that can be used directly as a fuel, or converted to another form of fuel or energy product. Biomass feedstocks are the plant and algal materials used to derive fuels like ethanol, butanol, biodiesel, and other hydrocarbon fuels. Examples of biomass feedstocks include corn starch, sugarcane juice, crop residues  such as corn stover and sugarcane bagasse, purpose-grown grass crops, and woody plants. “

Renewable Energy Group (REG) performed a study in 2009 with the support of the Iowa Power Fund Board and the Iowa Office of Energy Independence that tested 36 individual feed-stocks.  Star Oilco will be spotlighting these feedstocks through our blog and our social media. The full report can be found on their site if you would like to read ahead or explore the results in more depth. We hope you find these as interesting as we did!

                                                            Babussa Oil & Beef Tallow

Babassu Oil

Attalea speciosa

Babassu oil is extracted from the seeds of the babassu palm tree, Attalea speciosa, an evergreen tree growing to 30 m (98ft) by 20 m (65ft) at a slow rate. It is hardy to zone (UK) 10 and is not frost tender. The flowers are pollinated by bees and other insects. The tree is common in Brazil, Mexico, and Honduras; it grows well in areas typically cultivated for coconut or palm. The kernels contain 60-70% oil, appear transparent, and smell like walnuts. In its natural form the oil is liquid at 20-30°C (68 – 86°F). The seeds are edible and the oil is used in margarine, soaps, detergents, lamp oil and skin products. Oil extraction results in a cake containing 15-25% protein (depending on the shell content), which is a valuable feedstuff.

In February 2008, Babassu palm oil and coconut oil were blended with jet fuel to power a Virgin Atlantic Boeing 747 during a test flight from London’s Heathrow to Amsterdam.

Beef Tallow

Tallow is a rendered form of the waste fats and greases from processing beef. Rendering is a process by which lipid material is separated from meat tissue and water under heat and pressure. Beef tallow is primarily made up of triglycerides and it is solid at room temperature. The B100 that is created from this source has a very high cloud point. “Cloud point is the temperature at which wax (paraffin) begins to separate when oil chilled to a low temperature, and it serves as an important indicator of practical performance in automotive applications in low temperatures.”  (Source)  The other uses for tallow include animal feed, soap, cooking and in the past, candles.

Portland Retail Fuel Price Variance

Fuel Market News

Fuel prices varied this past week as gas prices increased slightly and diesel prices dipped. Gas prices increased by $0.13/gal on the rack average market and dropped $0.06/gal on the retail street market. Diesel prices dropped $0.10/gal across the board for rack averages, while the retail street average did not move from the week prior. As mentioned in earlier reports, gas prices should come down in the coming weeks with the winter fuel blend back on the market. Fuel prices typically reach their lowest price level from October to December every year. We can expect the same in the coming weeks. Oil prices are also currently below $62/barrel, which will help contribute to lower prices.

fuel-market-report-star-oilco-5-18-24

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”.

Reasons For Price Variance

Oil Prices Below $62

Winter Blend Of Fuel Back To Market

Crude oil is trading just below $62, at a current price of $61.52/barrel. This is $1.59/barrel lower than it was last week.

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 $61.52/barrel compared to $63.11/barrel last week and $69 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.

Portland Retail Fuel Price Variance

Fuel Market News

Fuel prices trickled down this past week with both wholesale rack averages and retail street prices down. Rack averages in Portland dropped $0.10/gal on E10 gasoline, and dropped less than $0.02/gal on diesel across the board. This trickled down into the retail market as street prices are down about $0.05/gal in Portland. The Olympic Pipeline is back online and the winter-blend of fuel is coming back to the market. We should see prices continue to come down slightly in the coming weeks as winter fuel hits stations across Oregon. Fuel prices typically reach their lowest levels during late fall/early winter every year so we should see downward pricing in the weeks ahead. For more information on prices, visit our website for weekly updates.

Person looking through binoculars in an autumn forest with vibrant fall colors reflected in both lenses, symbolizing focus on Oregon’s diesel and CO2 credit market conditions.
Oregon Diesel Market Forecast Fall 2025 1024 1024 Star Oilco

Oregon Diesel Market Forecast Fall 2025

What market forces are impacting the Oregon diesel outlook?

The US market is short diesel in storage while the Oregon market is short CO2 credits causing a unique market condition as we head into fall.

Diesel prices in the Pacific Northwest have not been following National trends for diesel.  The west coast is paying a premium compared to other nearby states.  Diesel in Oregon is significantly higher than the national average.  More to the point, the carbon credits associated with biodiesel and renewable diesel in Oregon are trading at recent record high prices. Higher than California’s CO2 credit prices. What’s going on?

Well for once it isn’t the price of crude oil causing this, or the amount of biofuels. Its all about todays Oregon diesel and carbon markets.  The story starts a few weeks before Memorial day.

Memorial day is often cited as the kick off to the driving season.  It also is when we usually see construction and trucking pick up with the summer weather.  A few weeks before Memorial day the Olympic pipeline went down unexpectedly.  The Olympic pipeline serves Portland and Eugene with their diesel and gasoline fuels from the refineries in northwest Washington state.

That pipeline had an unexpected outage.  Those happen for plenty of reasons usually safety checks or repairs. When the pipeline went down the market was notified it would probably be a week and open again the Monday before memorial day.  That Monday, the Monday before one of the bigger fuel weekends of the year, came and notice went out the pipeline would still be down for another week.

At that moment supply was already short for gas and diesel. Especially diesel.  The Portland and Eugene market saw diesel like a dollar cheaper in states like Idaho, Utah and others. So guess where diesel started flowing from? Markets responded as the bigger players on the ground in Oregon started moving diesel from those states.  Your local truck stops, gas stations, and cardlocks didn’t run out of fuel in several parts of Oregon because of these efforts.

In a US diesel market that was already tight for diesel supply, Portland, Oregon had an event that made it even tighter demanding diesel from around the region. Markets responded sending higher price offers to bring diesel into Oregon. Source is US EIA.

Oregon does not have any petroleum refineries or even biofuel plants.  It can only be supplied by pipeline, barge, rail or truck from outside the state.  When the pipeline came back online quite a bit of outside diesel had flowed into the state from nontraditional sources by rail and truck.

The people who moved that diesel are regulated in Oregon with two programs for CO2 emissions.  One is called the Clean Fuels Program which requires anyone importing diesel into Oregon to come up with a CO2 reductions by either blending low carbon biofuels or buying CO2 credits from others that use those fuels in the state.  Oregon also has a Cap and Invest program which only allows so much fossil fuel to be sold inside Oregon in a calendar year.  Oregon caps the total market for fossil fuels sold at retail stations as part of it’s carbon reducing strategy.

Guess what happens when a bunch of suppliers start bringing in gas and diesel to meet the market need?  They have to come up with Carbon credits and allowances to meet those carbon reduction programs for liquid fuels.  When unexpected volumes of diesel get imported into Oregon the CO2 market dynamics change.

For diesel, they need to start blending biofuels such as renewable diesel and biodiesel.  So since that Memorial Day pipeline outage the people who imported diesel from other states need CO2 credits under Oregon Clean Fuels Program as well as to ensure they done sell to many additional gallons of fossil fuel diesel to exceed the allowance of Oregon’s cap and invest regime.

Therefore CO2 credits are high, people are trying to blend more biofuels to catch up to the unexpected volumes of diesel they moved into Oregon.  Prices are higher than the rest of the US for diesel as a hangover to the supply disruption.

Upside for the first summer in a few years there is plenty of Renewable Diesel in the Portland, Oregon market as the CO2 credit prices are higher than California and the diesel prices are also high to help.  In the last month we have seen a huge amount of Renewable Diesel show up into the terminals in Portland.  So hopefully we will see lower prices heading into fall as all this works itself out.  As we pass by Labor Day the market cost of diesel should normalize and return to a much more affordable price.

The one downside of high diesel prices is that it makes Renewable Diesel the same price as fossil diesel.  If you want to try it, now is a good time where you can get it affordably and field test it for results with your fleet.  Want to see how it performs in reducing truck regens, EGR services, and see if fuel economy improves with a cleaner burning synthetic diesel running in your fleet.  This fall is a good time to experiment with it.

If you want to try Renewable Diesel in your fleet.  Star Oilco has it immediately available.  Please reach out to give it a try at either our Cardlock locations, with Mobile Onsite Refueling in your yard, or a Loaner Bulk Tank trial of the fuel in a few trucks.

Star Oilco has Renewable Diesel seven days a week for your fleet: Mobile Onsite Fueling, Cardlock, and Bulk Delivery.

Fuel Market News

Gas prices have trickled back down this week as the Olympic pipeline has been back online and is supplying throughout the PNW. The past two weeks were filled with a massive price jump in gas, with retail averages above $4.50/gal. We should continue to see these numbers fall back this week. Rack averages for Portland are down $0.49/gal for E10 gasoline, while diesel prices did not move more than $0.01/gal. This is the biggest price drop we have seen for gas in months, but it was expected after the Olympic pipeline was offline. As we roll into October, retail stations will switch back to the winter blend of fuel, which may cause a temporary price spike due to logistics, but will be followed by further price dips throughout the market.

September 2025 U.S. average gas and diesel prices compared to yesterday, last week, last month, and last year.

Fuel Market News

Gas prices skyrocketed this past week while diesel prices remained stagnant. The maintenance shutdown of the Olympic pipeline caused gas prices to increase by over $0.20/gal in just a week. Diesel prices moved $0.005/gal, with next to no movement on diesel prices. Commuters in Portland saw retail gas prices over $4.50/gal during the past week, and prices have yet to come down. The Olympic pipeline is back online this week, with capacities back to normal. We should see prices fall this coming week with the pipeline maintenance complete and the switch to winter fuel approaching.

Fuel prices are up across the board this past week, with both diesel and gas jumping over $0.15/gal. Rack averages in Portland jumped $0.20/gal for E10 gasoline and $0.16/gal for diesel. This comes on the heels of the Olympic pipeline maintenance this past week, after issues arose within the pipeline system requiring un-forecasted maintenance. This directly affects supply throughout the PNW, creating pricing bubbles throughout Washington, Oregon & California. Gas prices are expected to continue to climb this week, with maintenance yet to be fully completed. This will also roll into the switch from Summer blends of fuel to Winter blends of fuel, which will begin in the coming weeks. This may temporarily spike prices, with pricing drops thereafter.

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”.

Reasons For Price Variance

Oil Prices Below $65

OPEC+ Production Boosts For September

Crude oil is trading just below $65, at a current price of $62.35/barrel. This is $2.37/barrel lower than it was last week.

 

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 $62.35/barrel compared to $64.72/barrel last week and $68 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.

Getting the fuel for your generator or emergency equipment is only one part of the problem.  How you store it can be just as important.  This is why its important to work with a company that can help you.

You want to stabilize and treat your diesel for generators and other back up equipment.

Order fuel treated for long term storage!

Star Oilco is an expert at fueling back-up generators, emergency water pumps, and other long term off-road diesel storage requirements. We understand, that in the Pacific Northwest, biodiesel blending is required by state laws. Biodiesel needs an extra layer of care when stored as a back-up diesel fuel.Filling a Generator in the Snow

Most off-road diesels and heating oils are ultra-low sulfur diesel containing at least 5% quantity of biodiesel.  This means long term storage requires a proactive approach.  You can’t just hope it works or wait to see if the fuel will burn after years of storage.

Emergency back-up generator diesel fuel is a specially treated oxidative stabilized off-road fuel designed to store for years.

Fueling a backup generator is a specialized product. The fueling service requires a vendor who understands your needs and keeps you up and running in an emergency.

Generators take off-road diesel, of course, but you want an ultra-low sulfur diesel to ensure it works with modern emission systems. Some companies deliver higher sulfur product that look the same but foul the emission systems of your equipment.

Beyond the service provided, you also want a vendor who offers a fuel stabilizer and biocide for the special long term storage needs of your backup generator. Star Oilco recommends you add a biocide and long-term storage stabilizer to your fuel to ensure it is good whenever you need it.

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

Biocides prevent the growth of biological activity in the tank. In scenarios where micro-organisms like algae, bacteria, yeasts, and other bugs are growing in your fuel, biocides 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, turning over the fuel or using a filtration can remove this.

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. We use Valvtect Bioguard Plus 6 for generators, emergency water pumps, backup boiler fuel, and other long term storage purposes. This product kills any existing biological growth and stabilizes your fresh diesel fuel for long term storage. Make sure your diesel is ready the next time you need backup power.

Water in diesel destroys fuel quality rapidly.

Check your tank for water every fall and spring.

Pumping the tank bottom removes water if it ever finds its way into your storage tank. 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 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.

OIL VS. GAS – Which fuel is safer?

While a leak in your oil tank may cause temporary inconveniences, there have been no deaths or injuries associated with leaking oil tanks. The risks of injury are far greater with natural gas leaks and the statistics from the U.S. Department of Transportation’s Office of Pipeline Safety show that between 1986-1998, natural gas pipeline accidents have resulted in the deaths of over 200 people, injured more than 1,700 people, and caused more than $300 million in property damage. So safety is a legitimate concern.

Is natural gas cleaner and more efficient?

This is a misperception that is refuted by studies done by the U.S. Environmental Protection Agency, and the U.S. Dept. of Energy. According to these studies, heating oil and natural gas produce approximately the same levels of pollutants. Natural gas is not cleaner than heating oil. According to the U.S. Dept. of Energy and the Gas Appliances Manufactures Association, heating oil equipment is actually more efficient, on average, than natural gas heating equipment.

Is either natural gas or oil better for the environment?

No. Both fuel sources cause similar amounts of pollutants in the environment. Many environmentalists are concerned about the risks to our wetlands, river and forests, that will be the impact of gas pipeline construction, and about leaks and accidents that have occurred in existing pipelines. Further, many have expressed concern about natural gas as it is a power greenhouse gas which contributes to global warming.  If you are interested in heating with a fuel that is environmentally friendly, ask us about our biodiesel home heating oil.
