Diesel rose 6.1 cents to $4.026 a gallon, its seventh straight increase and the first time it has topped $4 in three months, the Department of Energy reported.
Gasoline, meanwhile, gained 2.3 cents to $3.744 a gallon, DOE said late Monday following its weekly survey of filling stations.
The diesel increase left trucking’s main fuel 21.6 cents above the same week last year, while gas is now 16.3 cents over a year ago.
Diesel had not topped $4 since May 14, according to DOE records. Gasoline is also at its highest level in three months.
The gains followed higher oil prices, as crude finished the trading day Friday over $96 a barrel, its highest level since mid-May, Bloomberg reported.
Crude futures slipped 4 cents to finish the trading day Monday at $95.97 a barrel on the New York Mercantile Exchange, Bloomberg said.
Each week, DOE surveys about 350 diesel filling stations to compile a national snapshot average price.
