The national average retail price of a gallon of diesel increased for the sixth consecutive week, climbing 0.6 cent to $2.674 for the week ending Monday, Aug. 31. The price — which has climbed 17.8 cents since July 20 — is the highest recorded this year, but is still $1.447 less than the same week last year, according to the U.S. Department of Energy.
All regions tracked by DOE saw price increases except for three: the Gulf Coast saw a 0.4 cent dip to $2.618, the nation’s least expensive diesel by region; the Central Atlantic region saw a 0.2 cent decrease to $2.779; and prices in the Lower Atlantic region were unchanged at $2.649.
The largest increase by region, 2.1 cents, was found in the Rocky Mountains, where week-over-week prices climbed to $2.692. The smallest increase by region, 0.1 cents, was found in New England, where week-over-week prices climbed to $2.742.
The nation’s most expensive diesel by region, $2.802, was found on the West Coast, where prices climbed 1.7 cents. California, which DOE tracks separately for its weekly update, saw a price increase of 1.3 cents to $2.893; still, that price is $1.389 cheaper than last year.
