What happens here

Upon completing the 310.7-mile test drive, the presenter reviews the results. He displays the truck's trip odometer reading of 310.7 miles and then checks the average MPG displayed on the overhead console, which now shows 20.2 MPG. This indicates a notable improvement from the initial 15.6 MPG baseline. The presenter expresses satisfaction with the performance of the Hot Shot's Secret EDT, concluding that the additive significantly enhanced the truck's fuel economy, even with a heavy load.

Goal: Determine the increase in fuel economy and conclude the test's outcome.
