The average price of a gallon of on-highway diesel in the U.S. is now $2.597 for the week ending Jan. 9, up 1.1 cents over the previous week and 4.2 cents higher than the same week in 2016, according to the Department of Energy’s weekly report.
Prices increased in all regions during the week except for the Gulf Coast region, which saw a three-tenths of a cent drop. The most significant increase came in the Central Atlantic region, where prices rose 3.7 cents. This follows a jump of 8.9 cents in the region the previous week.
