Portland Retail Fuel Price Variance
Fuel Market News
Fuel prices are down across the board this past week, as expected with winter fuel blend on the market and oil prices reaching their lowest price point of the year. Rack averages dropped $0.14/gal for gasoline and $0.08/gal for both B5 & B20 diesel. Fuel prices should continue to fall in coming weeks as oil prices are at the lowest price since 2021. Retail prices for fuel in Portland have not dropped much compared to rack averages but this should change in coming weeks as we roll into autumn and winter in the coming weeks. The refinery fires at Chevron’s El Segundo refinery put a temporary bottleneck on supply and prices in previous weeks but have since been resolved as prices continue to fall.
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”.
