The Dearborn-based auto club says late Sunday the average price for self-serve regular unleaded gasoline was about $2.29 per gallon. That's about 32 cents more than it was at the same point last year.
AAA says the lowest average price was about $2.23 per gallon in the Flint area. The highest average was about $2.33 in the Ann Arbor area.
The Detroit-area's average is about $2.30 per gallon, roughly 4 cents less than last week's average.
AAA Michigan surveys daily fuel prices at 2,800 gas stations across the state.
