AAA Michigan says gas prices statewide have increased by about 14 cents in the past week.
The Dearborn-based auto club says the average price for self-serve regular unleaded gasoline was about $2.74 per gallon on Sunday. That's about 15 cents less than it was at the same point last year.
This is the fifth consecutive week that the statewide price has increased.
The lowest average price was about $2.56 per gallon in the Marquette area, while the highest average was about $2.77 per gallon in the Ann Arbor area.
AAA Michigan surveys daily fuel prices at 2,800 gas stations across the state.
