Diesel fuel fell 2.7 cents to $2.219 a gallon, continuing a 30-week downward trend and leaving it at the lowest level in nearly four years, the Department of Energy said Monday.
The decline left the national average price of trucking’s main fuel $1.061 below the same week last year and at the lowest level since it registered $2.16 on May 30, 2005.
Diesel has fallen in 28 of the 30 weeks since July, gaining only 0.1 cent at the end of September and 2.3 cents during a week in mid-January, DOE figures showed.
Gasoline, meanwhile, rose 3.4 cents to $1.926, the highest since Nov. 17, when it topped $2 a gallon, at $2.072.
Gas — which has risen 31.3 cents from an almost five-year low of $1.613 set six weeks ago — is $1.034 less than the same week a year ago.
Crude oil has hovered around $40 a barrel for the past week, down more than $100 from the $145.29 closing-price record set last July 3 on the New York Mercantile Exchange.
Each week, DOE surveys about 350 diesel filling stations to compile a national snapshot average price.
