The national average price for a gallon of on-highway diesel fell below the $3 mark for the first time since September 2010 and its lowest point since the week ended Sept. 6, 2010, according to numbers released Jan. 19 by the Department of Energy.

The U.S. average at-pump price for diesel dropped 12 cents in the week ended Jan. 19 to $2.933 a gallon, according to the DOE. The price is now down 94 cents from the same week last year and has fallen nearly 70 cents since the beginning of December.

All regions in the U.S. saw big drops, too, led by a 15.2-cent decline in the West Coast less California region. The Rocky Mountain regional average dropped 14.3 cents, the second biggest drop.

The California subregion had the country’s most expensive diesel, $3.165 a gallon, followed by the Central Atlantic’s $3.131.

The West Coast less California region had the country’s cheapest diesel, $2.826, followed by the Gulf Coast’s $2.843 and the Rocky Mountains’ $2.884.
