The average U.S. price of regular-grade gasoline jumped 15 cents over past two weeks to $4.38 per gallon.
Industry analyst Trilby Lundberg of the Lundberg Survey said Sunday that the current price sits just a nickel below the highest average price in history — $4.43, set on March 11.
The average price at the pump is $1.36 higher than it was one year ago.
