The average U.S. price of regular-grade gasoline jumped 2 cents over the past two weeks, to $2.96 per gallon. Industry analyst Trilby Lundberg of the Lundberg Survey said Sunday that the increase came as crude oil costs also rose. The price at the pump is $1.03 higher than it was a year ago. The highest average price in the nation right now is $4.04 a gallon in the San Francisco Bay Area. The lowest average is $2.49 in Baton Rouge, Louisiana. The average price of diesel is unchanged over the same period, at $3.13.
