Diesel dipped 0.7 cent to $3.911 a gallon, its sixth straight decline, the Department of Energy reported.

Trucking’s main fuel has declined 23.9 cents from its more than four-year high of $4.15 on Oct. 15 but is now 8.3 cents over the same week last year.

Gasoline’s national average price was flat, gaining 0.1 cent to $3.299 a gallon, leaving the price 8.3 cents below a year ago, DOE said Monday following its weekly survey of filling stations.

Diesel has declined in 11 of the past 12 weeks, and including Monday’s dip, three of its past six downturns have been less than a penny.

Gasoline has risen for three straight weeks by a total of 4.5 cents, according to DOE figures.

Oil, meanwhile, rose a dime Monday to finish the trading day at $93.19 a barrel on the New York Mercantile Exchange, the highest closing price since Sept. 18, Bloomberg News reported.

Each week, DOE surveys about 350 diesel filling stations to compile a national snapshot average price.
