Matt Folkman
Saved $17,000
“Lifetime savings over $17,000. No cost if I don’t use it. It’s a no brainer!!! And more and more stations let you put the code in at the pump which saves time too.”
- Kurt B
Saved 91 ¢/gal
“The app is so easy—go inside, show a code, pump, done. $3.94/gal to $3.03/gal… does not get easier than that.”
- Stamp M
Great customer service
“This is the first fuel card that we have had that I have actually received great customer service on all our issues. That goes a long way with us.”
- Jenny S, JM Trucking
Card controls and fleet credits at any station
“I love the Mudflap Fuel Card because we are not stuck trying to find a truck stop, since it's accepted anywhere Visa is accepted. Also, we get fleet credits for out of network stations that we can use towards fuel. I can turn the cards off if I don’t want them used by drivers. Just the best all the way around.”

Mudflap is the real deal
"I wish more people knew about this app. So many owner-operators and fleets use regular fuel cards and get a lousy 10-15 ¢/gal discount on overpriced fuel. This is the real deal. Seriously love this app and the money it saves me. 10/10 recommend coming from a person that's been in trucking for 13 years."
- Manpreet G
Excellent savings in hard times
“Excellent savings in hard times. The attendant knew exactly what Mudflap was, put my code in and I was all set to go!”
- Kimberly F
Total peace of mind
"As a one truck operator this is the best system I've found! Been using it a couple years now and it has saved me thousands. Plus the convenience and security of not having a card compromised or lost gives me total peace of mind. Finally, customer service is absolutely second to none!!!”
