Diesel’s national average fell 0.8 cent to $3.94 a gallon, its fifth straight decline, while gasoline fell 1.3 cents to $3.781, the Department of Energy said Monday.
Diesel’s sixth downturn in seven weeks left it 18.4 cents below the $4.124 price of four weeks ago, which was the highest since August 2008.
Trucking’s main fuel is now 99.4 cents higher than the same week a year ago, according to DOE records.
Gasoline has declined for four straight weeks and is now almost 18 cents below its two-and-a-half year high of $3.965, set four weeks ago. Gas is $1.056 over last year, DOE said.
After holding near $100 a barrel for the past two weeks, oil fell $1.21 Monday to finish at $99.01 on the New York Mercantile Exchange, the first time it has closed under $100 since May 24, Bloomberg reported.
Each week, DOE surveys about 350 diesel filling stations to compile a national snapshot average price.
