Really helps with the cost of fuel here in California. Especially when towing the 30ft rv. Thank you for the great prices overall. I'll be a loyal customer for quite a while to come.

I would be even happier with Mudflap if I could just enter the code at the pump.

Wonderful app! I have saved hundreds of dollars. The app is convenient and user friendly. The "Route" option is perfect for planning ones stops at mudflap friendly facilities. I do wish all the fuel codes could be entered at the pump, but it is still an excellent asset!

Response from Mudflap, Inc.Jun 5, 2025
Hi Dana, Thanks for taking the time to leave us a review. Our business model has never called for making money off of drivers by charging fees, and it still doesn’t. The small 1.9% credit card processing fee helps cover the cost of supporting credit cards as a payment method in the app. Mudflap's credit card fee is low because we continue to subsidize a significant portion of the processing cost for credit cards. You can avoid this credit card fee by paying with a debit card or linked bank account. Call us if you’d like help setting this up at 1-888-885-3835 or reach out to us at [email protected].
