Gas prices are on the rise again in Minnesota – especially in the southern half of the state. The statewide average is now $3.35 per gallon, which represents a 40-cent increase since early January. Triple-A Minnesota’s Gail Weinholzer blames Canada and crude oil for the spike in prices. She says the gas we’re getting from Canada is more expensive than fuel from the Gulf of Mexico, and that 6 US oil refineries are closed, including two in the Chicago area that provide fuel to Minnesota. Demand for gas is expected to remain low through the winter months.
