Diesel rose a half-cent to $4.021 per gallon, its sixth increase in seven weeks and the highest price in almost a year, the Department of Energy reported March 10.
Diesel is at its highest level since March 18, 2013, when it was $4.047.
The price is 6.7 cents lower than the corresponding week last year, DOE said after its weekly survey of filling stations.
Gasoline, meanwhile, gained 3.3 cents to $3.512 a gallon, its fifth straight increase.
Gas, which has jumped 22 cents in the past five weeks, is at its highest level since Sept. 16.
Despite the increases, gasoline is 19.8 cents below the corresponding week last year, DOE figures showed.
Trucking’s main fuel has risen 11.8 cents from the end of December, DOE figures showed.
