The average weekly retail on-highway diesel price slipped for the fourth consecutive week, this time falling 0.7 cent to $2.931 for the week ending Monday, Sept. 6, according to the U.S. Department of Energy. The price, which has fallen 6.0 cents since Aug. 9, is 28.4 cents higher than the same week last year. DOE’s weekly roundup of diesel prices was delayed one day because of the Labor Day holiday.
Regions tracked by DOE saw a mix of increases and decreases. The biggest increase, 0.3 cent, was found on the West Coast, where prices climbed to $3.104, the nation’s highest price by region. The smallest increase, 0.2 cent, was found in the Rocky Mountains, where prices climbed to $3.021.
The biggest decrease, 1.3 cents, was found in the Central Atlantic, where prices fell to $3.007. The smallest decrease, 0.1 cent, was found in New England, where prices dipped to $2.995. The nation’s lowest price by region, $2.876, was found on the Gulf Coast, where prices fell 1.2 cents.
