The discounts are big enough to make using Mudflap worthwhile. If you run into problems they’re easy to get ahold of on the phone for help. I have not run into a problem yet that the team couldn’t fix right away! More and more places are getting where you can enter your code at the pump! It’s just great, I love it!!

It’s easy to use and I’m happy with the savings. I’m a tri-state driver, so I only need to go three states all I need but boy you can really get the scope of what destination you’re going to the next day and whether I need to fuel the next day. It’s nice to know

The app works really well. I like to be able to locate the different prices from the different stations around and the customer service is is awesome.

I like Mudflap and truly the savings. Only thing I dislike is that Mudflap doesn’t pull the money right away. Or at least keep the pending on the account till the funds are pulled out. This way my balance has all fuel purchases are subtracted out.

Hi there, we really appreciate you sharing your experience—and we’re so glad to hear you’re enjoying the savings! It sounds like you might be referring to the standard authorization hold that occurs when using a credit or debit card in the Mudflap app. This temporary hold helps confirm that funds are available, and any unused amount is released right after fueling or canceling your code. Depending on your bank, it may take a few business days for the update to show in your account. If you'd prefer to avoid holds altogether, switching to a bank account as your payment method can help. Our support team will be reaching out soon to learn more and help you find the best solution.

Prices are great. Plenty of locations. I use the card, works great, except for a few older locations, then you have to go inside.

Decent app but need better discounts and quit charging card fees.

I love the MudFlap app except the new feature that's lock you out and have to call in to get number at pump because I was a snow bird last winter and drove a gas vehicle all winter so when I was ready to drove 3000 miles home , I was shut off and every fill I had to call in that was a pain . I think for security it's ok to shut me off but if I call in once then you should be able to turn it back on with our me having to wait a week or two until it automatically turns back on . Very inconvenient
