Portland Retail Fuel Price Variance
Fuel Market News
Fuel prices dipped this past week in Portland, as rack averages for gasoline had its biggest single-week price drop this year, of over $0.30/gal. This comes on the heels of the Olympic pipeline getting back to operational status after a 10-day shutdown in the weeks before. Fuel prices across the board have dropped this past week, as rack averages for diesel were also down $0.04/gal. Surprisingly, these price dips have yet to hit the retail street market, as the retail fuel prices are still relatively high at a current average of $3.84/gal & $4.38/gal for diesel. We should see prices continue to fall on the wholesale market as oil prices are low, inventories are high, and demand has been consistent.
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”.
