The average retail price of diesel fuel in the United States surged 1.5 cents per gallon to $1.453, the U.S. Department of Energy reported Monday.
This followed a 0.1-cent decline the week before and left commercial trucking's dominant fuel at its highest point since $1.484 on May 5.
It was also the largest one-week increase since March 10, when diesel hit an all-time high of $1.771.
The most recent increase would add $30 to a 200-gallon purchase of diesel at retail pumps. The price is 14.9 cents higher than this time last year, DOE said.
DOE also said the average price for regular gasoline rose 2 cents to $1.536 per gallon, the highest in more than three months.
Still, gasoline, used by about one-third of trucking, is down almost 20 cents from a record $1.728 set on March 17.
The price of diesel increased throughout the country, with all of DOE's geographic regions reporting an increase of more than 1 cent with the exception of the East Coast grouping of states.
The Midwest saw the largest increase, 2.1 cents, to $1.43.
Each week, DOE surveys 350 diesel-filling stations to compile a national snapshot price of diesel and gasoline.
