Gas prices across Michigan have tumbled an average of 32-cents per gallon this week, based on a new survey from AAA Michigan. The Auto Club's latest fuel gauge survey shows Michigan’s current statewide average is now at $2.52 per gallon. That's also one-dollar eight cents less than this same time last year. Of the cities surveyed by AAA the lowest average price is in the Marquette area at $2.41 per gallon. The highest average price is in the Lansing-East Lansing area where its $2.61 per gallon. The Auto Club says the sharp decline is due to the restarting of the BP oil refinery in Whiting, Indiana.
