These price averages are generated daily and are calculated as the average across the following states: NE, IA, ND, SD, MI, WI, MN, KS, MO, IL, IN . Prices are managed by Mudflap’s merchant partners and are subject to change without notice to or input from Mudflap.
Savings vary by stop in the Mudflap network, amount of fuel purchased, and market conditions.
