After six consecutive weeks of increases, the national average retail price of a gallon of diesel fell 2.7 cents to $2.647 for the week ending Monday, Sept. 7. The price — which had climbed 17.8 cents since July 20 — is $1.412 less than the same week last year, according to the U.S. Department of Energy, which delayed its weekly report one day because of the Labor Day holiday.

All regions tracked by DOE saw price declines. The biggest decrease, 4.5 cents, was found in the Lower Atlantic, where prices fell to $2.604. The smallest decrease, 1.0 cent, was found in the Rocky Mountains, where prices slipped to $2.682.

The nation’s most expensive diesel by region, $2.786, was found on the West Coast, where prices slipped 1.6 cents. The nation’s least expensive diesel by region, $2.575, was found on the Gulf Coast, where prices fell 4.3 cents.

California, which DOE tracks separately for its weekly update, saw a price decrease of 2.7 cents to $2.866; that price is $1.319 cheaper than last year. For state-by-state diesel prices, updated daily, click here.
