Diesel’s national average price dipped 1.6 cents to $3.87 a gallon, its sixth decline in eight weeks, the Department of Energy reported Oct. 28.
Gasoline, meanwhile, fell 6.6 cents to $3.294, its seventh decline in eight weeks and the lowest price this year.
Gas is now 27.4 cents lower than the same week a year ago, and its price has plunged 31.4 cents in the past two months.
The diesel decline followed no change in the price last week and left trucking’s main fuel 16 cents less than the same week last year, DOE said following its weekly survey of filling stations.
The price has not increased in any week in the past two months, as it was unchanged in two of the past eight weeks, according to DOE records. The cumulative downturn in that time has been 11.1 cents.
Gasoline is at its lowest level since it was $3.257 last Dec. 24, according to DOE records.
Each week, DOE surveys about 400 diesel filling stations and 800 gasoline stations to compile national average prices.
