Best way to do it practically.
Fill the tank to the top..
Reset the odometer (write down the odometer reading)
Fill the tank again to the top.
Take the amount from the second fill up that's the gallons used.
Take the mileage, lets say 300 miles between fill ups then divide that by the amount of gallons that you put into the tank, lets say 12. Your MPG would be 25.
Total miles / Fuel used.

Divide the number of miles you drove by the number of gallons you used. The easiest way to do it is to fill the tank up completely but don't top off. Drive. Record miles driven. Fill up at same gas station don't top off again. Divide the miles driven by how much gas you just pumped in.

Fill your gas tank and note the mileage.
Drive until it is at least half empty. Refill the gas tank to full. Note how much fuel you put in and how many miles you drove between your first and second fillup.
Divide the miles by the gallons = your MPG.

How many miles (look at trip meter) divided by the number of gallons of gas in a fillup (look at receipt).

every time I get gas I reset the trip meter. Each time I get gas I note how many gallons it took to fill up. Divide that number into the number on the trip meter, then re set trip meter.
