The price has slipped 4.4 cents in three declines. It fell 2.5 cents last week and a half-cent two weeks ago after six straight gains totaling 16 cents.
The decline left trucking’s main fuel $1.012 less than the corresponding week last year, DOE said after its weekly survey of filling stations.
Gasoline, meanwhile, rose 5.5 cents to $2.835, marking the eighth increase in nine weeks. The price was unchanged last week, so the motor fuel has not declined in two months.
Its price has risen 42.7 cents since mid-April and is 85.1 cents below its level of a year ago, DOE figures showed.
Crude oil futures fell 44 cents June 15 to finish New York Mercantile Exchange trading at $59.52 a barrel, the lowest closing price in a week, Bloomberg News reported.
Each week, DOE surveys about 400 diesel filling stations and 800 gasoline stations to compile national average prices.
