Fuel Market News
Fuel prices are up this week across the board as diesel and gas prices increased by over $0.10/gal. Rack averages in Portland jumped $0.13/gal for regular E10 gasoline, and $0.20/gal for B5 & B20 diesel. Oregon is still within the top 10 states for the highest fuel costs for January, with a current average price of $3.33. Although the average in Portland is significantly higher at $3.65/gal. Fuel prices should continue to maintain at their current price levels until April/May, when the switch back to summer blends of fuel begins to come back into the market. Crude oil is still hovering just below $60/barrel for WTI crude, which is contributing to the maintained lower fuel prices.
