QuickMPG is the easiest way to calculate your gas mileage and compare it to your prevous fill-up. It’s one screen with big buttons. And it’s FREE.
A change in your car’s gas mileage could indicate a mechanical problem. Keep track of what’s normal for your vehicle with just a few taps. To use it, set your trip meter to zero at your next fill-up. Drive around a bit. Then, at your next fill-up, enter the number of miles you traveled as well as the gallons it took to fill your tank.
