Diesel dipped 1.1 cents to $3.858 a gallon, its fourth consecutive decline and lowest price in eight months, the Department of Energy reported July 28.
The price was the lowest since trucking’s main fuel averaged $3.844 on Nov. 25, and the downturn left it 5.7 cents below the same week last year, according to DOE records.
Diesel has declined in 16 of the past 20 weeks since topping out at $4.021 per gallon March 10, its highest level in almost a year.
Gasoline, meanwhile, fell 5.4 cents, to $3.539 a gallon, DOE said following its weekly survey of filling stations. The motor fuel has plunged 16.5 cents in four straight downturns.
The decline — the biggest since a 7.1-cent drop in mid-November — left gas at its lowest level since March 10 and 10.7 cents below the comparable week last year.
