In This video I test the avg MPG gauge on a Toyota Prius. The Toyota Prius calculates your average miles per gallon and shows it to you on the dashboard, but is it accurate? I miss video, I drive more than 300 miles and check the trip miles per gallon and miles traveled versus the number of gallons it took to fill up the tank, and I test the accuracy of the average miles per gallon gauge on a Toyota Prius third generation. I find out that it’s off by almost 4 miles per gallon. It is showing a higher miles per gallon than the Prius actually gets. The Toyota Prius Still gets great gas mileage, but the average miles per gallon gauge is in accurate. Watch his video to see how accurate the mpg gauge on a Toyota Prius is.
