The national average retail price for a gallon of diesel dropped 1.4 cents, to $2.448, for the week ending over the holiday weekend, according to the U.S. Department of Energy.
Averages dropped or stayed constant in every region except the West Coast, where fuel rose 18 cents, to $2.523. The Midwest saw the biggest drop, 23 cents, ending the week at $2.420. Prices in the Rocky Mountain region held steady at $2.410. The Gulf and East Coasts had averages falling to $2.421 and $2.418, respectively.
The decline in the national average is uncommon for this time of year because of the increased demand for heating oil. However, national average prices are 46.1 cents higher than a year ago.
