Michigan Gas Prices Surge to New High

Michigan's gas prices have hit their highest mark of the year so far, averaging $4.93 per gallon as of September 21st. According to AAA-The Auto Group, this is a 62-cent increase from last week and a whopping $1.75 higher than the same time in 2025.

The national average price has also seen an uptick, with GasBuddy reporting it at $4.44 per gallon, a 19-cent increase since last week. The price in Detroit is about $4.90 a gallon, up 60 cents from last week, according to the Dallas-based fuel tracker's survey of 1,734 stations in Detroit.

Motorists in Michigan are paying an average of $74 for a full 15-gallon tank, an increase of about $23 from last August's high, AAA reported. Patrick De Haan, head of petroleum analysis at GasBuddy, attributed the trend to refinery issues in the Great Lakes region and continued strikes on Russian oil refineries tightening global diesel supply.

The Energy Information Administration (EIA) reported that gasoline demand rose from 8.55 million barrels per day to 8.79 million, while total domestic gasoline supply climbed from 206.9 million barrels to 207.7 million. However, crude oil inventories dropped by 0.6 million barrels from the previous week.

Regional prices also saw a significant jump, with Detroit's pump price being 69 cents higher than last month and $1.75 per gallon higher than a year ago. The cheapest station in Detroit was $4.19 on Sunday, while the most expensive reached $6.09.
