Portland Retail Fuel Price Variance
Fuel Market News
Fuel prices trickled down this past week with both wholesale rack averages and retail street prices down. Rack averages in Portland dropped $0.10/gal on E10 gasoline, and dropped less than $0.02/gal on diesel across the board. This trickled down into the retail market as street prices are down about $0.05/gal in Portland. The Olympic Pipeline is back online and the winter-blend of fuel is coming back to the market. We should see prices continue to come down slightly in the coming weeks as winter fuel hits stations across Oregon. Fuel prices typically reach their lowest levels during late fall/early winter every year so we should see downward pricing in the weeks ahead. For more information on prices, visit our website for weekly updates.
