Michigan gas prices remained $3.25 a gallon Sunday, the same price, on average, it was a week ago, but it is expected to drop as refineries switch to winter-blend gasoline, which tends to cost less. Some metro Detroit stations on Sunday already were selling gas below $3 a gallon.

Gas prices are expected to stay under $3 per gallon, on average, through the end of 2024. They could drop another 10 to 25 cents this fall.
