The national average price for a gallon of on-highway diesel fell nine-tenths of a cent in the week ended May 26 to $3.925, according to the Department of Energy’s Energy Information Administration.
This is the fourth week in a row the price of diesel has declined nationally, and the national average price is down a nickel in that time period.
The DOE predicted in April that the national average price would be $3.87 this summer, so the drops could be the start of that decline.
Year over year, however, the price of diesel is up 4.5 cents from the same week last year.
Prices fell week to week in all regions except the West Coast and the West Coast less California.
The Midwest led all price decreases with a 1.7-cent drop, followed by a nine-tenths of a cent drop in the Central Atlantic and New England regions.
The West Coast less California region led all increases with a six-tenths jump, followed by the West Coast’s two-tenths jump.
The New England region still has the country’s most expensive diesel, $4.13, followed by the Central Atlantic’s $4.127 and California’s $4.109.
The Gulf Coast again had the nation’s cheapest diesel, $3.783, followed by Midwest’s $3.884 and the Lower Atlantic’s $3.916.
