Mudflap

Fuel savings and truck routing in one app

Mudflap is a Maps & Navigation app for professional truck drivers who want to find diesel discounts and plan routes suited to commercial vehicles. It combines fuel stop search with truck-aware GPS guidance, making it useful for long-haul drivers, regional carriers, and owner-operators.

Diesel discounts at participating stops

The app lists discounted diesel at more than 2,800 truck stops across the United States. Available locations include networks such as TA Petro, Speedway, Kwik Trip, Sapp Bros, Casey’s, Maverik, AMBEST, and Road Ranger.

Navigation built around truck restrictions

Mudflap also includes free GPS navigation for truck journeys. Routes are designed to help drivers avoid problems such as low bridges, weight limits, and roads restricted to certain vehicles. You can enter a destination directly or plan a route toward a selected fuel stop, keeping fuel planning and navigation together.
