Diesel dipped 0.7 cent to $3.913 a gallon, while gasoline slid 2.6 cents to $3.678, the first declines for both fuels in three weeks, the Department of Energy reported July 7.

Diesel’s downturn left it 8.5 cents higher than the same week a year ago, while gas is 18.6 cents over the same week last year, DOE said following its weekly survey of filling stations.

With the exception of two weeks in June when it was in the high $3.80s, diesel has topped $3.90 every week since mid-January, according to DOE figures.

Trucking’s main fuel rose 3.8 cents in its previous two weeks of increases, which followed a 9.3-cent drop in the preceding seven weeks.

Gasoline fell for just the second time in the past seven weeks — it was flat last week from the previous week — and its latest price is the lowest in a month.

Each week, DOE surveys about 400 diesel filling stations and 800 gasoline stations to compile national average prices.
