Average retail gasoline prices in Michigan have risen 12.8 cents per gallon in the past week, averaging $3.72 per gallon Sunday.

This compares with the national average that has fallen  in the last week to $3.56 per gallon, according to gasoline price website MichiganGasPrices.com.

Including the change in gas prices in Michigan during the past week, prices Sunday were  lower than the same day one year ago and are higher than a month ago.

The national average has decreased during the past month and stands  lower than this day one year ago.

“While price decreases have heated up on the West Coast, such decreases are drying up in other areas- such as the Great Lakes,” said Patrick DeHaan, a senior petroleum analyst for GasBuddy.com.
