The average price of a gallon of regular-grade gasoline fell a nickel nationally over the past two weeks to $2.51.
Industry analyst Trilby Lundberg of the Lundberg Survey said Sunday that the drop comes as distribution systems continue to get back to normal following disruptions from late-summer hurricanes along the Gulf Coast.
Gas in San Francisco was the highest in the contiguous United States at an average of $3.07 a gallon. The lowest was in Baton Rouge, Louisiana, at $2.14 a gallon.
The U.S. average diesel price is $2.76, down about a penny from two weeks ago.
