Mr. JackHammer ,

Best thing since ice cubes !!!!

I love this app me and technology don’t get along too well it’s easy to use and it saves me money so since I own my truck and since fuel prices have been going up I’ve been stopping more at the smaller truckstops because they’re cheaper than the chain truckstops but now with this app I get like a double savings I get the cheaper prices at the mom and Pop but then I get a discount on top of that and all my taxes are paid you can’t beat that I just started using it I’ve used it three times in from the cheaper price in the area as opposed to the major truckstops I got that savings and then I got an additional savings which so far has saved me over $100 in less than a week how can you not love that all the people at mudflap of been very nice answered all my questions help me at first set up they’re awesome! Thank you for developing this app

This is real help at the pump to your wallet!!!

I’ve used company fuel cards that help you save in big name fuel stations, only to see the savings roll back to - the fuel card. Accumulation of savings is awesome, don’t get me wrong, but I am not getting it unless I accumulate enough rollback money. The only positive would be a free shower if I use it in a certain time. This is a much different story with Mudflap App. The rollback returns directly to my wallet! Some fuel locations offer free showers and at times a free drink, something the big truck stops stopped offering!!! For my money, I’d rather accumulate money back to my wallet to use as I please rather than to roll into a company card where I see my savings but forced to use only for fuel.

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.🙏🙏
