The U.S. average retail price of diesel rose 0.3 cent to $3.079 a gallon, according to the Department of Energy, as crude oil prices advanced slightly.
The national average price of diesel is 10.3 cents more than it was a year ago, when the price was $2.976, DOE said after its March 11 survey of fueling stations.
The increase was the fourth consecutive rise in the average weekly diesel price, totaling 11.3 cents.
But average prices for diesel did not rise in every region.
Diesel prices went up the most in the Central Atlantic region, 1.4 cents to $3.315 per gallon. Prices declined in three regions, dropping the most in the Lower Atlantic, 0.4 cent to $2.981.
