Portland Retail Fuel Price Variance
Fuel Market News
Fuel prices jumped again this week due to the shutdown of the Olympic Pipeline. Supply of gasoline was very tight throughout the PNW over the holiday week due to the Pipeline shutdown. Rack averages for E10 in Portland jumped over $0.09/gal while rack averages for B5 & B20 diesel jumped $0.05/gal. As of 12/01, the Pipeline is back to full operation and is supplying throughout the PNW. With the pipeline back in operation, WTI crude being below $60/barrel, and the winter blend of fuel on the market, fuel prices should fall slightly this week and continue to do so in the weeks ahead. The national average price for gasoline reached its lowest point since 2021 last week at $2.83/gal, although prices are still quite a bit higher in Washington, Oregon & California—still, a good sign for fuel prices in the weeks ahead.
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”.
