The U.S. average retail price of diesel rose 1.3 cents to $3.055 a gallon, the Department of Energy reported July 8. Crude oil slid to below $58.
Diesel still costs 18.8 cents less than it did a year ago when it was $3.243, DOE said.
Regional diesel prices climbed in five areas and fell in five others.
Diesel remained the highest in California despite a one-cent drop and was $3.953.
Also, the national average price for regular gasoline jumped 3 cents to $2.743 a gallon, DOE’s Energy Information Administration said.
Regional averages fell in three areas and increased in six others.
Meanwhile, the latest data, covering 2018, shows California’s Low Carbon Fuel Standard continues to drive production of a growing volume of cleaner transportation fuels: almost 3.3 billion gallons of petroleum diesel have been displaced by clean, low-carbon alternatives, according to the California Air Resources Board.
