A slight dip in diesel fuel prices during the week ending June 4 halted a 10-week run of rising prices across the U.S., according to weekly numbers from the Department of Energy.
Diesel prices dropped by just three-tenths of a cent during the most recent week, bringing the U.S.’ average price for a gallon of on-highway diesel to $3.285.
Prices dropped in most regions during the week, but a six-tenths of a cent increase in California took the state’s average above the $4 per gallon mark.
With that increase, California continues to be home to the nation’s most expensive diesel at an average of $4.003 per gallon, followed by the West Coast less California region at $3.508 per gallon.
The cheapest fuel can be found in the Gulf Coast region at $3.055 per gallon, followed by the Lower Atlantic region at $3.166 per gallon.
Prices in other regions, according to the DOE, are:
- New England – $3.302
- Central Atlantic – $3.442
- Midwest – $3.224
- Rocky Mountain – $3.359
