Portland Retail Fuel Price Variance
Fuel Market News
Gas prices dipped slightly, and diesel prices saw significant price jumps this past week. Rack averages in Portland were down $0.03/gal while diesel prices were up over $0.10/gal on B5, B20, and R99. Renewable diesel prices dipped significantly this month, with prices as low as $2.50/gal. The Portland market’s need for Renewable Diesel will continue to be high in demand as the 2026 RFS deadline approaches, with diesel blends increasing to B50 blends. Questions of supply remain unclear, with Neste pulling out of the market in early 2025. Much remains unknown about the future supply of diesel in Oregon. Demand will be very high, and supply will need to be strong to support this. Where the supply comes from remains unknown for most. The winter blend of gas and diesel will soon be back on the market as we roll into September next week. This may create an initial increase in prices, with pricing dips following into October/November. Oil prices have remained slightly below $65/barrel. OPEC+ has announced a production boost headed into September, which may lead to crude oil prices below $60/barrel into the fall/winter.
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 trading just below $65, at a current price of $64.72/barrel. This is $1.38/barrel higher 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 $64.72/barrel compared to $63.34/barrel last week and $69 a year ago.
