Gasoline, meanwhile, dropped 6.8 cents to $3.368, its biggest decline in seven weeks, DOE said.
Monday was the first time diesel’s national average price has topped $4 since May 16, according to DOE records.
Diesel is now 83.9 cents over the same week last year, DOE said following its weekly survey of filling stations. Gas is 49.2 cents over a year ago.
Oil finished the trading day Thursday at $102.59 a barrel — the first time it closed over $100 since June.
