Mudflap fueling app is awesome

We have only used it 4 times but the experience using it is great and it doesn’t take anymore time using as it is with a regular fleet card. So far it has been saving me a little more money also. They deal with the smaller chain and mom & pop fueling stations. I’m going to keep using them as much as I can. The only negative I have is needing fueling stops in North Dakota and Montana, but they are growing, but not a big enough deal to take a star. Customer service is second to none, you get top quality responses and everyone has been very courteous and helpful. Highly recommend using your system. Thank you very much.🙏🙏

Best Way To Fuel

If you like saving thousands on fuel then you’ve come to the right place. This app is so easy to use and has everything the big name fuel card providers do without all the extra fees. All you have to do is download the app then link your card or bank account to it and start fueling no wait, fuel card, or approval period needed you just use the MudFlap app on your phone. 100% legit, I’ve used it several times now without any problems. And their fuel network are both big name truck stops and smaller locally owned ones too not just one or the other.

Comdata vs Mudflap

I travel from Ogden Utah to out side Detroit Michigan on a dedicated route as an owner operator. My company gave me a comdata fuel card to use. I pay for all fuel costs. I get charged $1-5 for each swipe of that Comdata card. Adds up over time. The discount are the same on Comdata as with Mudflap. Sometimes Mudflap is cheaper. My dedicated fuel stops I pick out I use Mudflap and don’t get a fee to use plus great discounts
