The average price of gasoline has remained steady over the past two weeks, holding at $2.71 a gallon.
Industry analyst Trilby Lundberg said Sunday that while the average remains unchanged, many Midwestern cities saw prices jump due to a partial shutdown of an Indiana refinery. Many West Coast cities experienced price drops.
The cheapest price recorded in the continental United States was Charleston, South Carolina, at $2.10.
The highest was $3.67 a gallon, in Los Angeles.
The national average price of diesel was down 6 cents over the same period, to $2.72 a gallon.
