Fuel Market News

Fuel prices soared this past week again as the U.S & Iran peace agreement has entirely collapsed. The most recent military strike by Iran hit U.S bases in Jordan, killing multiple US service men/women. This war has no end in sight, and the general public in the U.S remains very uninformed as to why the peace agreement continues to be violated. The national average gas price is yet again over $4.00/gal. As fuel prices climb once again and the average American struggles with continued inflation, the US government has spent over 3 trillion dollars of taxpayers’ money fighting an unexplained war in the Middle East.

Retail gas prices in Portland are just under $5/gal, averaging around $4.85/gal, while the Seattle area is currently $5.56/gal.  Retail diesel prices in Portland are just under $6/gal at a current average of $5.59/gal, while the Seattle area is over $6.37/gal. Crude oil is up $20/barrel in the last 12 days.

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 has jumped over $15/barrel and is currently hovering just above $90/barrel, at a current price of  $90.81/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 $90.81/barrel compared to $83.57/barrel last week and $73 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.

Fuel Market News

Fuel prices jumped up this week as the U.S & Iran peace agreement has yet again proven to be extremely unstable, as military strikes have been re-initiated within the region, causing crude oil to shoot up 8% in 5 days. A very real problem that nobody seems to be talking about is the depletion of the federal oil reserve, which is at its lowest level since August 1983 at about 45% capacity. This should be much bigger news than it is, with no end in sight to the war with Iran

Retail gas prices in Portland are just under $5/gal at a current average of around $4.75/gal, while the Seattle area is at $5.45/gal.  Retail diesel prices in Portland are just under $6/gal at a current average of $5.55/gal, while the Seattle area is over $6.20/gal. Crude oil prices have jumped back this week as the U.S & Iran have once again started to bomb one another’s strategic assets. The doubters of the peace deal between the US & Iran were right yet again, as the peace agreement has gone to the wayside and military action and bomb strikes have resumed. This conflict truly has no end in sight, and the general public remains grossly uninformed by the U.S government about what is going on and what the timeline is.

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.

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.

Fuel Market News

Upon the news of a potential peace agreement between the US & Iran, crude oil prices took a steep dip, causing fuel prices to follow. It will take a week or more of continued stability and peace between the regions for drivers to see the real price difference as prices continue to fall. The question is how real this peace agreement is and how long it will last. Global markets have responded very positively, with stock markets going up and crude oil prices dropping. President Trump announced that the Strait of Hormuz has reopened entirely, ending the naval blockage and bottleneck of the entire region.

Retail gas prices in Portland are still over $5/gal at a current average of around $5.12/gal, while the Seattle area is over $5.76/gal.  Retail diesel prices in Portland are still over $6/gal at a current average of $6.01, while the Seattle area is over $6.75/gal. As of June 8th, the main pipeline in Washington state is down for maintenance. The Olympic pipeline has been fixed and is back to full operational status. This, with the combination of a hopeful end of the conflict in the Middle East should continue to push fuel prices lower into this week and next.

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.

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. Additionally, prices may vary by specific regions within Oregon and Washington.

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.

Fuel Market News

Fuel prices jumped yet again this past week with heightened tensions between Iran & The United States. We are currently entering day 74 of this war. This prolonged conflict has sent a ripple effect through the entire market, disrupting supply chains as far as food packaging and labeling. This past week, prices jumped 8% since April 30th. Prices are up on both the wholesale market and the retail market. Portland currently has an average diesel price of over $6.25/gal, with Seattle over $6.99/gal. President Trump has said the Iran ceasefire is “on life support,” which has sent crude oil prices higher yet again, with many analysts still unclear what is next. Iran has most recently proposed charging fees to international companies using fiber optic internet cables that run through the Strait of Hormuz. These seven different cables consist of FALCON, GBI, and Gulf-TGN and are critical to global data and financial traffic. If Iran were to cut these cords or take full control of them, the effects would be immense.

This conflict has continued to draw bipartisan disapproval as the current cost estimates exceed $22 billion.
