DEARBORN, Mich., (September 14, 2026) - Gas prices in Michigan are up 28 cents from a week ago. Michigan drivers are now paying an average of $4.31 per gallon for regular unleaded. This price is 6 cents more than this time last month and $1.04 more than this time last year.

"Michigan drivers are seeing a significant increase at the pump, with gas prices reaching levels we haven’t seen since early August ," said Adrienne Woodland, spokesperson, AAA-The Auto Club Group. "This sharp increase underscores the ongoing volatility in global oil markets and serves as a reminder of how quickly fuel prices can shift."
