Although the price of a gallon of on-highway diesel rose just 2.3 cents during the week ended Nov. 21, the U.S. average diesel price crossed a notable threshold by exceeding $4 a gallon for the first time since mid-May, according to the latest figures from the U.S. Department of Energy’s Energy Information Administration.
That price is 83.9 cents higher than the same week last year.
Prices in all regions tracked by DOE gained, led by a 5.1-cent jump in the Rocky Mountain states, where prices climbed to $4.144. The smallest increase was 0.1-cent in California, where the average price is a nation-leading $4.271. As usual, the nation’s least expensive diesel was in the Gulf Coast region, where the average price was up 2.1 cents to $3.903.
The record diesel price was $4.764 in July 2008.
