Diesel fell for the eighth week in the past ten, declining 6.2 cents to $3.888 a gallon, the Department of Energy said Monday.
Gasoline, meanwhile, fell 7.8 cents to $3.574, its seventh straight decline and the biggest drop in five weeks.
Gas has fallen 39.1 cents since hitting a more than two-and-a-half year high of $3.965 on May 9, according to DOE records.
The diesel decline — the biggest since a 6.4-cent drop on May 23 — followed a 0.4-cent dip last week, DOE said following its weekly survey of filling stations.
Trucking’s main fuel is now 93.2 cents higher than the same week last year and 23.6 cents below its $4.124 price on May 2, the highest in more than two-and-a-half years.
Crude oil fell 55 cents Monday to finish New York Mercantile Exchange trading at $90.61 a barrel, the lowest level in more than four months, Bloomberg reported.
Each week, DOE surveys about 350 diesel filling stations to compile a national snapshot average price.
