Mudflap consistently offers larger discounts per gallon, with savings averaging $0.25-0.50 off retail. Instafuel provides competitive but slightly lower discounts at most locations.
Mudflap has a larger and faster-growing network of participating truck stops. Instafuel's network is smaller but includes some exclusive locations not on Mudflap.
Both apps are straightforward, but Mudflap's interface is slightly more polished and the transaction process is smoother. Mudflap's map-based station finder is particularly well-designed.
Instafuel offers slightly better fleet management features including spending controls and driver-level reporting. Mudflap is catching up but was originally designed for individual owner-operators.
Instafuel supports more payment methods including ACH, fleet cards, and credit cards. Mudflap primarily works with ACH payments and checking accounts, which may not suit all users.

Mudflap wins on the factor that matters most — savings per gallon. Their larger discount margins and broader station network mean more money in your pocket on more of your stops. For an owner-operator who fuels 1,000+ gallons per month, Mudflap's superior discounts can save $250-500 monthly.
Instafuel is a solid alternative with better fleet management features and payment flexibility. Carriers managing multiple drivers may prefer Instafuel's administrative tools.
Many drivers use both apps and check prices at each stop to maximize savings — they are free to download and there is no exclusivity requirement.
