The U.S. average retail price of diesel fell 1.1 cents to $3.160 a gallon. Oil prices slipped to $61 a barrel as the United States and China imposed higher tariffs on the other’s goods, which chilled the outlook for demand.
Diesel costs 7.9 cents less than it did a year ago, the Department of Energy said.
Regional diesel prices were mixed, lower in seven regions and higher in three. The top price was in California, where diesel climbed 3.9 cents to $4.136 a gallon. The lowest price was in the Gulf Coast region, where it dropped 2.2 cents to $2.905.
Also last week, the national average price for regular gasoline fell 3.1 cents to $2.866 a gallon, DOE’s Energy Information Administration said.
The national average is 0.7 cent lower than a year ago, EIA said.
