The average price of a gallon of diesel fuel nationwide took its biggest drop in 16 weeks, declining 3.3 cents to $3.094 a gallon, according to US Department of Energy information.
This decrease was the biggest since a 5.2-cent drop February 1, turning around three months of increases in which the price had fallen just once.
The only other downturn since mid-February was a 0.7-cent dip March 29. Monday’s decline left diesel 86.3 cents over the same week in 2009.
The previous week’s half-cent uptick to $3.127 had put trucking’s main fuel at its highest level in more than a year and a half.
