Diesel edged up 0.8 cent to $3.902 a gallon, its first increase in eight weeks, the Department of Energy reported.
The gain leaves trucking’s main fuel 5.4 cents higher than the same week last year, DOE said late Tuesday following its weekly survey of filling stations.
Gasoline, meanwhile, rose for the fifth straight week, gaining 1.2 cents to $3.315 a gallon.
Despite the increase, gas, which has risen 6.1 cents in the past five weeks, is now 7.4 cents under the same week a year ago.
This week’s diesel upturn is just the second in the past 14 weeks; its only other increase was a 5.8-cent gain on Nov. 26.
Diesel is about 25 cents below the $4.15 per-gallon average from mid-October, which was the highest in more than four years.
