The average national price of a regular gallon of gasoline has jumped 13 cents in the past two weeks to $2.58.
Industry analyst Trilby Lundberg said Sunday that higher crude oil prices caused the run-up at the pump. However, the price is $1.11 below the mark a year ago.
Los Angeles has the highest-priced gas in the Lower 48 states at $3.30 a gallon. The low average was in Tucson, Arizona, at $2.20.
The average price in California is up 17 cents, to $3.23.
Lundberg says pump prices could climb by a few more pennies as gasoline prices catch up to oil prices.
