In the news, a recent Transport Topics article says that the Department of Energy's latest report shows diesel’s national average pump price fell for a 12th straight week, declining 3 cents to $3.648 a gallon. This drop left diesel 20.2 cents below the same week last year. Trucking’s main fuel has plunged 50 cents and gasoline has plummeted 58.5 cents in the past three months, according to DOE records.
