Michigan Gas Prices Reach 2025 High Amid Midwest Refinery Issues

Michigan gas prices reached a new 2025 high of $3.39 per gallon for regular unleaded ahead of the Labor Day weekend, driven by refinery issues in Whiting, Indiana, and increased demand coupled with decreased domestic gasoline supply. Since that peak, prices have declined to an average of $3.30 per gallon statewide, which is 15 cents more than last month but 7 cents less than the same time last year. Metro Detroit's average is slightly lower at $3.30 per gallon, with price variations across the state: Ann Arbor has the highest prices around $3.37, while Marquette offers some of the cheapest fuel at $3.13 per gallon. Motorists filling a 15-gallon tank are paying about $49, roughly $8 less than the highest prices seen last July. AAA suggests that as the Whiting refinery comes back online, motorists may see further relief at the pump.
