After several weeks of near-stability, the average retail price of a gallon of on-highway diesel shot up 8.7 cents to $3.943 during the week ended Monday, Feb. 13, according to the U.S. Department of Energy’s Energy Information Administration. It is the largest one-week swing in either direction since a 10.2-cent jumps in mid-April 2011. The latest price is 40.9 cents higher than the same week last year.
Prices rose in all regions, led by the Midwest where prices were 10.6 higher than the week before. The smallest increase by far was 2.4 cents in the Rocky Mountain region, which also enjoyed the nation’s least expensive diesel on average at $3.841 a gallon. Of the 10 regions tracked by DOE, six now have average diesel prices above $4 a gallon. The nation’s most expensive diesel is in California, where the average price is $4.209.
