LANSING (AP) - The worst may be over for drivers in the upper Midwest who have been grappling with the highest gasoline prices in the continental U.S.
Analysts said one major Illinois refinery is back online and another big one in Indiana is on track to ramp up production again soon. The refineries' ongoing maintenance - which led to reduced supply and higher prices - are the primary culprits for the surge at the pump.
"On balance I think the worst is over," Tom Kloza, chief oil analyst at GasBuddy.com, said Tuesday.
Exxon Mobil's refinery in Joliet, Ill., was offline longer than expected, he said. Assuming there are no hiccups with BP's plans to soon restart a crude unit at its refinery in Whiting, Ind., prices could drop below $4 a gallon within weeks throughout a five-state region stretching from Wisconsin to Ohio, according to experts.
"You just have one refinery issue after another. As they're coming back on, that should be a big thing," said Phil Flynn, chief energy analyst at Price Futures Group in Chicago.
AAA said Michigan's average price of a gallon of unleaded regular gas was $4.20 on Tuesday, topped only by Hawaii and well above the national average of $3.63 per gallon. Motorists in Illinois, Indiana and Wisconsin were paying above $4 on average, while drivers in Ohio were shelling out $3.90.
With many people preparing to hit the road for their summer vacations, public anger over the high price of gas is building in Michigan. One Republican lawmaker is drafting a bill designed to entice construction of a new refinery in the state and Democrats are questioning the state attorney general's commitment to investigating high prices.
Anton Fellinger, who lives near Detroit in Macomb County's Washington Township, finds the high pump prices particularly acute with his 2008 Chevrolet Silverado.
"My blood boils every time I put gas in it," he said. "I'm biting the bullet right now, but if this continues I might pull the trigger and get something that gets me 30 miles per gallon."
Fellinger, who drives about 18 miles to work, found a more economical mode of transport on Tuesday: his motorcycle. But that option is limited in northern states such as Michigan. His saving grace on days he drives the Silverado is a local gas station that offers free car washes for customers who buy at least eight gallons of gas.
"I've just been racking up the free car washes," he said. "I might as well get something out of it."
