Gas prices have decreased since last week according to AAA Michigan. The current statewide average is about $2.30 per gallon, down 11 cents from last week and almost $1.50 less than last year at this same time. It's the first time in almost two months that gas prices have decreased.

The cheapest prices for self-serve unleaded fuel can be found in the Flint area where it's about $2.17 per gallon. The highest average can be found in the Traverse City area where it's about $2.43 per gallon.

AAA believes the national average price of gas could rise by 20 cents per gallon or more in March as refinery maintenance season continues. However, prices should remain much lower compared to recent years due to cheaper crude oil costs and above average gasoline supplies.

AAA surveys 2,800 Michigan gas stations daily. For more information, including cheapest gas prices in the nation, visit www.AAA.com.
