Testing Procedure
The Mileage Max was developed and tested by Edges engineers using a Mustang dynamometer to duplicate typical driving conditions. Both input and return fuel lines from the test truck were run into a separate tank containing a known quantity of fuel placed on an extremely accurate digital scale. With the truck fully warmed, the trucks cruise control was set to 70 MPH in overdrive and a constant load applied to simulate highway loads. The weight of the consumed fuel was then subtracted from the original weight and converted into MPG.
Repeated test results showed the Mileage Max consistently delivered up to a 7% improvement in fuel economy (depending on year and model of the vehicle) and up to 35 extra horsepower. In order to ensure accuracy, several tests were performed and an average made with and without the Mileage Max using the same conditions on the same dyno.
