CAMARILLO, Calif. (AP) — The U.S. average price of gasoline dropped 27 cents over the past three weeks, to $2.44 a gallon.

Industry analyst Trilby Lundberg said Sunday that the pump price fell even though crude oil prices gained strength, as gasoline supply outweighed demand.

Further price drops are likely if crude oil prices don’t skyrocket, because the Sept. 15 change to winter grade gasoline comes with a cost cut in much of the country.

The cheapest price recorded in the continental United States was Charleston, South Carolina, at $1.94.

The highest was $3.31 a gallon in Los Angeles.

The national average price of diesel was down 9 cents over the past three weeks to $2.63 a gallon.

As of Sunday, Sept. 13, at 7 p.m., the lowest price for gas in South Bend was $2.03 at Murphy USA, 620 W. Ireland Rd. near S. Main St., according to Gas Buddy. The lowest price for gas in Elkhart was $2.12 at Marathon, 2701 Prairie St. & W. Hively Ave, Gas Buddy reported.
