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.
