The national average price for a gallon of diesel continued to drop, falling almost 9 cents to $2.51 for the week ending Monday, Nov. 21.
Only a month ago, the per-gallon price set a record at $3.16 as then-prices refused to fall in the wake of high diesel demand and a grueling series of hurricanes in the oil-rich Gulf Coast.
This is the fourth week in a row per-gallon prices hovered below $3, according to the U.S. Department of Energy. Still, the price is 40 cents higher than the same week last year.
The Rocky Mountains had the highest average at $2.654, followed by the West Coast at $2.652, the Gulf and East coasts at $2.491, and Midwest at $2.477.
The Rocky Mountains showed the largest one-week drop in price, falling 11 cents.
