The unexceptional price of a gallon of regular-grade gasoline jumped 3 cents nationally all through the past three weeks to $2.54.
Industry analyst Trilby Lundberg of the Lundberg Study said Sunday that the increase is due to higher crude oil costs.
The up to date gas price is 16 cents above where it was a year ago.
Gas in San Francisco was the highest in the contiguous Coalesced States at an average of $3.22 a gallon. The lowest was in Tucson, Arizona, at $2.10 a gallon.
The U.S. usual diesel price is $2.94, up 6 cents from three weeks ago.
