COLUMBUS -- Ohioans can feel good about filling up, because AAA said the state now has the nation's lowest gasoline prices.

The auto club said at Ohio stations, a gallon of regular now averages $2.29 a gallon, about 30 cents below the national average.

AAA said gas prices have been falling nationwide because the end of the summer driving season has brought a drop in demand.

The Ohio Petroleum Council says prices are low in the Buckeye State because there's so much competition, especially from retailers such as Wal-Mart and Giant Eagle that sell fuel. The trade group's executive director, Terry Fleming, told Columbus TV station WCMH that he expects prices to remain stable or maybe go even lower.
