Diesel fuel prices jumped more than 3 cents just before Memorial Day.
The increase was the first in the last 6 weeks, after a more than a six cent decline.
The average price of a gallon of on-highway diesel is now $2.571. All the Regions in the
U.S. increased except New England where it fell 4 tenths of a cent. California still maintains
the highest price at $2.931 per gallon. The lowest price remains in the Gulf Coast at $2.423.
