I don't like it holds money on your account. it holds up to $400.00 even if you only get $90.00 fuel and it's not returned for 2 days.

Help save on fuel and you are bringing in a lot of new stations I have been trying to get more discounts and I can't find a way to get it done

Easy in easy out. I would like to see some rates on regular fuel as well.

I do occasional over the road transport and their app makes it easy to find stations with fuel discounts and map out a route ahead of time so I have a good understanding on where to stop along the way. Overnight parking can be a pain and the app shows where there is space and where there is not so I don't have to get off at an exit and check for myself

I've been using mudflap well over a year maybe even over two honestly. It's always a positive thing to save money. The reason I'm only give you three stars is because it seems there is not much effort to sell their product. Even though I have looked up local truck fuel stations and shared their phone numbers with mudflap support, there is still only one along the state route I am using 90% of the time. The other reason is they have still not incorporated DEF into the system.

Always quick and easy transactions. Sometimes with big discounts. Need more locations.
