Diesel fell for a fourth straight week, dropping 3.4 cents to $2.946 a gallon, its lowest price in 10 weeks, the Department of Energy said Monday.
Gasoline also fell for the fourth straight week, dipping 0.3 cent to $2.725 a gallon, DOE said following its weekly survey of filling stations.
Diesel’s downturn left it 44.8 cents more expensive than the same week last year, while gas is about a dime higher, costing 10.1 cents more at the pump.
Trucking’s main fuel has fallen 18.1 cents in the past four weeks after gaining 37.1 cents in the three months ending in mid-May.
Gas gained almost 30 cents in its upward run from mid-February through mid-May, and has declined 18 cents in the past four weeks.
Diesel’s price is the lowest since its national average was $2.939 a gallon on March 29 when it slipped 0.7 cent, its only decline in 12 weeks of increases.
Gas is at its lowest level since March 1, when it was $2.702 a gallon.
Each week, DOE surveys about 350 diesel filling stations to compile a national snapshot average price.
