Drivers in Plymouth, Michigan, and the rest of Metro Detroit are getting some relief at the pump. The Metro Detroit average for regular gasoline fell about 21 cents over the past week to $4.50 a gallon, the auto club AAA said Monday, though that is still $1.43 more than at this time last year.
Statewide, the average price for regular unleaded in Michigan dropped 22 cents from a week ago to $4.47 a gallon. That is 42 cents higher than a month ago and $1.36 more than a year ago. Filling a 15-gallon tank now costs Michigan drivers about $67 on average, roughly $16 more than at the peak price of 2025 last August.
AAA tied the weekly drop to weaker demand. Federal energy data showed gasoline demand fell from 8.84 million barrels a day to 8.68 million. Total domestic gasoline supply also slipped, from 206 million barrels to 204.4 million, and production fell from 9.59 million barrels a day to 9.46 million.
Metro Detroit remains among the most expensive areas of the state. Ann Arbor had the highest average at $4.54, with Jackson and Metro Detroit tied at $4.50, while Flint had the lowest at $4.28, followed by Saginaw and Marquette.
A Michigan State University economist said the U.S. conflict with Iran and its effect on oil supplies and shipping pushed fuel prices up sharply in recent weeks, and that prices would likely take time to return to normal even after the conflict ends.
