The auto club says that the average price of a gallon of self-serve regular unleaded gasoline was $3.49 on Sunday. That's about 17 cents less than one year ago.
Dearborn-based AAA Michigan surveys fuel costs at 2,800 Michigan gas stations daily. It says the cheapest price was $3.39 a gallon in the Lansing-East Lansing area and the most expensive was $3.68 in the Marquette area.
Nationwide, it says gasoline averaged $3.53 a gallon Sunday, compared with $3.58 last week and $3.64 last year.
AAA Michigan attributes falling U.S. gasoline prices to abundant refinery production and stable international oil markets despite the Russian-Ukrainian and Israeli-Palestinian conflicts.
