Driver FAQs

What is Mudflap?

Mudflap provides instant fuel discounts to thousands of owner-operators and small fleets at hundreds of independent fuel stops and chains like AMBEST, Roady’s, Casey’s, Road Ranger, Sapp Bros and more.

Why do I need to add a payment method (e.g. credit card) to the app?

To get instant discounts with Mudflap, drivers buy their fuel using the Mudflap app. Once you add your card, get a fuel code and pump your gallons, Mudflap will charge your credit or debit card for your discounted fuel purchase. You never need to show or give your card to the fuel stop.

Can I use a fleet card or fuel card as payment?

Mudflap can accept fleet/fuel cards that have a Mastercard / Visa logo on the front. If you can use your card to buy non-fuel purchases like convenience store items, that's a sign your card can be used on Mudflap.

How secure is the app?

Mudflap protects your payment information with the same bank-grade security and SSL encryption used by Amazon and Google. Your card information is always 100% safe and secure with Mudflap.
