How to calculate MPG (miles per gallon)

To figure your MPG if you don't already know, you can easily figure this out using these steps:

1. When your fuel gauge gets down to 1/4 tank, fill it up and record the number of gallons it took to fill the tank and the reading from the odometer at the time of fill up.


2. When the tank is at 1/4 again note the odometer reading again. Subtract this odometer reading from the first reading (from step 1) to get the number of miles travelled.


3. Divide the number miles calculated in step 2 by the number of gallons from step 1 to give the MPG.

You should follow these steps a few times and take an average to get a better estimate of the MPG.
