Portland Retail Fuel Price Variance

Fuel Market News
Fuel prices are up this week across the board as diesel and gas prices increased by over $0.20/gal. Rack averages in Portland jumped $0.24/gal for regular E10 gasoline, and $0.30/gal for B5 & B20 diesel. These price increases also hit the retail market, with prices up $0.13/gal on the AAA average. Crude oil is just above $60/barrel for WTI crude, up $2/barrel from the previous week. This is the highest increase in crude oil pricing we have seen in multiple weeks and is partially responsible for why prices jumped so significantly this week.

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 above $60, at a current price of $61.95/barrel. This is $2.52/barrel higher than the week prior.
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 $61.95/barrel compared to $59.43/barrel last week and $72 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.
