What is your miles per gallon? Miles per tank will be different for everyone, because unless you're willing to run your car out of gas your results can vary wildly.



Fill it up, write the miles down.



Drive around normally



At the next fill up, write down the new mileage, and subtract the old mileage. Divide that number by the gallons taken and you'll have your MPG.



Compare that number to the EPA estimate quoted above, and you'll know how you're doing. Keep in mind that mileage will vary from tank to tank and driver to driver. The EPA number is an estimate.Gas mileage?
