Gallon of gas jumps 7 cents

CAMARILLO, Calif. — The average price of a gallon of regular-grade gasoline jumped 7 cents nationally over the past three weeks to $2.65.

Industry analyst Trilby Lundberg said Sunday the increase is due to higher crude oil costs.

The current gas price is 34 cents above a year ago.

Gas in San Francisco was highest in the contiguous United States at an average of $3.42 a gallon. The lowest was in Tucson, at $2.26 a gallon.

The U.S. average diesel price is $3.04, up 5cents from three weeks ago.
