Diesel prices declined for the tenth straight week but not by much. The national average retail price for on-highway diesel dropped 0.6 cent to $3.845 a gallon during the week ended May 6, according to the U.S. Department of Energy’s Energy Information Administration. The national average price is at its lowest level since early August. Diesel prices are 21.2 cents lower than the same week last year.
Diesel prices fell in all but one region — the Midwest, where the average price rose 2.9 cents. California experienced the largest drop — 4.6 cents — but it still had the nation’s most expensive diesel on average at $4.001 a gallon. The Gulf Coast region has the nation’s cheapest diesel on average at $3.735 a gallon.
