Diesel and gasoline each edged up by less than a penny, with diesel rising 0.7 cent to $3.91 a gallon, the Department of Energy reported Jan. 6.
Regular gasoline gained 0.1 cent to $3.332 a gallon, DOE said after its weekly survey of filling stations.
Both fuels have risen for three weeks, although this week’s upticks were less than the past two.
Diesel’s rise followed a 3-cent upturn last week and a 0.2-cent gain two weeks ago. Gasoline jumped 9.2 cents in the past two weeks, including last week’s 6-cent increase.
Trucking’s main fuel is almost exactly where it was a year ago, with the retail price just 0.1 cent less than the same week last year. Gas is 3.3 cents higher than a year ago.
This week’s diesel price is the highest since late September, when it was falling after its $3.98 price on Labor Day, which was the highest level in the second half of 2013.
Each week, DOE surveys about 400 diesel filling stations and 800 gasoline stations to compile national average prices.
