About gas prices in Iowa
Iowa is Casey's General Store country, with hundreds of locations across the state that typically run among the cheapest pump prices in the Midwest. The state gas tax is around 30 cents per gallon, plus Iowa's ethanol-friendly market promotes E15 and E85 blends that often run 10 to 30 cents below regular unleaded for compatible vehicles. Des Moines, Cedar Rapids, and Davenport see the most competitive pricing thanks to Casey's, Kum & Go, Hy-Vee Fuel, and Costco competing for membership cards. Rural Iowa cooperative stations (Co-op and FS Energy) are often surprisingly competitive due to direct grain-and-fuel distribution relationships.
