CAMARILLO, Calif. (AP) – The average U.S. price of regular-grade gasoline has dipped 1 penny per gallon to $2.65 over the past two weeks. Industry analyst Trilby Lundberg says Sunday that further cuts to gas prices are unlikely because crude oil costs are on the rise. The price at the pump is 14 cents higher than it was a year ago. The highest average price in the nation for regular-grade gas is $3.74 per gallon in San Diego. The lowest average is $2.14 in Tulsa, Oklahoma. The average price of diesel is $3.06, down a penny.
