The Dearborn-based auto club says late Sunday the average price for self-serve regular unleaded gasoline was about $2.42 per gallon. That's about 51 cents more than it was at the same point last year.
AAA says the lowest average price was about $2.36 per gallon in the Detroit area, where it's up about 8 cents from a week ago. The highest average was about $2.51 in the Grand Rapids, Muskegon and Holland areas, up about 18 cents from a week ago.
AAA Michigan surveys daily fuel prices at 2,800 gas stations across the state.
