The average price of retail diesel fuel rose 3.7 cents to $2.877 a gallon, the Department of Energy reported Monday.
The gain was the third straight and the ninth in the past 11 weeks, over which time the price has climbed 46.4 cents, according to DOE figures.
Gasoline, meanwhile, jumped 7.4 cents to $2.876 a gallon, an 11th straight gain, DOE said. Over that time, the price of regular gas at the pump has jumped 71.1 cents a gallon.
Diesel is now 11.2 cents higher than the same week last year, while gasoline is 9.3 cents over the price of a year ago.
The diesel price increase was led by the East Coast, which rose 4.9 cents to $2.862. The West Coast remained the highest of the five DOE regions, climbing 3.5 cents to $2.956 a gallon.
In California, which DOE tracks separately but which is included in the West Coast price calculation, the price spiked 3.7 cents to $3.015, topping the $3 level for the first time since mid-September, according to DOE figures.
Each week, DOE surveys about 350 diesel filling stations to compile a national average price.
