Diesel rose 6.3 cents to $4.089 a gallon, its eighth straight gain and the highest price since mid-April, while gasoline rose again, the Department of Energy said Monday.
Gasoline gained 3.2 cents to $3.776 a gallon, also its eighth straight increase, DOE said following its weekly survey of filling stations.
The diesel increase leaves it 26.9 cents over the same week last year, while gasoline is 14.9 cents over a year ago.
In the past two months diesel has risen 44.1 cents, while gasoline is up 42 cents since early July, according to DOE figures.
Last week, trucking’s main fuel pushed past $4 a gallon for the first time in three months.
Oil, meanwhile, fell for a third day Monday, despite oil companies evacuating Gulf of Mexico rigs as Tropical Storm Isaac moved through the Gulf on a track toward New Orleans, Bloomberg reported.
Crude futures fell 68 cents to close the day at $95.47 per barrel on the New York Mercantile Exchange. Oil had finished last Wednesday over $97 a barrel, the highest closing price since May.
Each week, DOE surveys about 350 diesel filling stations to compile a national snapshot average price.
