Earlier this week AAA reported in its weekly Fuel Gauge Report that gas prices have risen since last week, most dramatically in the Midwest. The average price for a gallon of regular unleaded gasoline was $3.65 on Monday, May 20, which is 7 cents more than Monday, May 13. AAA said this is the largest increase since February and the highest average price at the pump since March. AAA said refinery maintenance and tight supplies are driving these increases.
