To figure your vehicle's miles per gallon (mpg) you will need to fill up your gas tank two times. The tank does not need to be completely empty when you fill it.
Difficulty: Easy
Time Required: 5 Minutes - Once Information is in Place
Here's How:
- Write down the exact mileage shown on your odometer and keep this figure in your vehicle.
- Fill your up your gas tank completely.
- Next time you need gas, write down the mileage shown on your odometer. Subtract this figure from the first mileage reading. This represents the number of miles that you traveled since your last fill up.
- Fill your up your gas tank completely and write down the number of gallons needed to fill your tank.
- Take the number of miles since your last fill up (figured instep 3) and divide this by the number of gallons needed to fill up your tank (from step 4).
- This is the number of miles per gallon that your vehicle is getting. Repeat these steps several times to get an average mpg for your car. Remember that highway driving uses less gas than city driving and different levels of ethanol will affect your mpg.
