Gas prices in Milwaukee, WI

About gas prices in Milwaukee, WI

Milwaukee sits in PADD 2 Midwest with pipeline access from Marathon's Catlettsburg KY refinery and BP's Whiting IN refinery. Wisconsin state gas tax is moderate at around 33 cents per gallon. Reformulated gasoline is required in southeastern Wisconsin through summer ozone season, adding 5 to 10 cents per gallon. Milwaukee typically runs close to the PADD 2 average but slightly below Chicago thanks to no Cook County excise stack. Drivers across the metro see meaningful pricing variation: stations in suburbs (Brookfield, Mequon, Greenfield) and along the I-894 outerbelt typically run 8 to 15 cents below downtown Milwaukee. Warehouse club density is high, with Costco locations in Menomonee Falls and Brookfield posting the lowest pricing most weeks.
