How to find out the mpg of your car

Here is one way to find out mpg if your car does not display it (most modern cars do).

When filling up the car, obtain (if using a card) or save (if paying by cash) the receipt. Fill up the car fully. On the receipt, write down the odometer reading. Also, reset the trip indicator and do not reset it until you are done with the calculation.

After some period of driving the car and towards the car being empty fill up the car fully again. Write down the cost per gallon of gas.

Price divided by cost per gallon of gas will tell you how much gallons of gas the difference between the two receipts was. Since you filled up to the top in both cases, the difference is how much gas your car used up. Divide the mileage on the trip indicator (or the difference between the current odometer reading and what you wrote down on the first receipt) by the gallons of gas consumed to get the mpg rating.


You may still have the EPA printout of advertised mpg rating of your car. If you feel that your mpg is too low, try the following:

For an older car, clean the MAF sensor. Vacuum out or replace engine air filter.

Make sure tires are not under-inflated.

Clean out any junk and unnecessary items from your car.
