The retail price for gasoline is coming off seasonal highs as the U.S. refining sector returns to normal after Hurricanes Harvey and Irma, AAA reports. The motor club lists a national average price for a gallon of regular unleaded gasoline at the retail level of $2.62, down about 2 percent from last week and the lowest in more than two weeks. Retail prices spiked in early September after Hurricane Harvey forced more than a dozen refineries, including one of the largest in the country, to close down. Demand pressures later increasedwhen Hurricane Irma hit Florida, which upended the market because the state has no refineries of its own.
