DEARBON, Mich. (AP) -- AAA Michigan says gasoline prices in the state dropped about 14 cents in the last week, the fourth straight week they've fallen.
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.
