AAA: Michigan gas prices fall below $4 per gallon

Michigan drivers are getting some much welcomed relief at the gas pump as the cost for regular unleaded has fallen below $4 for the first time since April.

Michigan gas prices went down 14 cents since last week, with a gallon of unleaded fuel costing an average of $3.96. The price is about 25 cents less than drivers were paying last month, but still around 80 cents more than Michiganders paid this time last year, according to AAA.

For a 15-gallon tank of gas, that equates to an average of $59 to fill up — an increase of about $8 from 2025’s highest price reported in August.

In Metro Detroit, average daily gas prices decreased to $4.01 — or about 13 cents less than last week’s average but still 81 cents more than the same time last year.

The most expensive averages reported by AAA were in Ann Arbor ($4.05), Metro Detroit ($4.01), and Lansing ($3.97), with the least expensive averages reported in Marquette ($3.62), Traverse City ($3.90), and Flint ($3.91).

Domestic gasoline supply decreased from 216.3 million barrels to 214 million, according to new data from the Energy Information Administration (EIA), while gasoline demand increased from 8.73 million barrels per day to 9.21 million. Gasoline production increased last week, averaging 10 million barrels per day.
