From AAA’s Fuel Gauge Report for June 24:

AAA: Motorists in 14 states and Washington D.C. are paying more for gas than a week ago, led by increases of eight cents per gallon in Calif. and Nevada. However, drivers in all other states are feeling welcome price relief as the busy summer driving season gets underway. These declines have been headlined by massive drops in the average prices paid by Midwestern drivers. Just weeks after prices in the region soared to new or near record-highs on regional supply and production issues, prices have just as dramatically reversed course, as refinery issues have been resolved and retail prices have come plummeting back to earth. Lingering production issues in the Chicago market, notably maintenance at the ExxonMobil refinery in Joliet, Ill., and the BP refinery in Whiting, Ind., had delayed price relief for some Great Lakes states, but with production coming back online the relief has been as swift as it has been welcome. The largest one-week drops nationwide have been Mich. (-30 cents), Ind. (-27 cents), Ohio (-24 cents) and Wisc. (-24 cents).
