How To Figure Out your Gas Mileage (MPG)

The term "gas mileage" refers to how many miles you can drive your vehicle on one gallon of gasoline. This measurement is known as "miles per gallon" or "mpg". If you're like most people you want to get as many miles per gallon as possible because it will save you a lot of money over time. In this article I will tell you how to figure out your gas mileage and give you a few ideas on how to make it better.

Checking your vehicle's gas mileage periodically is a good way of keeping track of its performance. After you calculate your mpg you can try some strategies to increase it, and then check it again later to see if it has improved.

1. Completely fill your vehicle's gas tank and reset the trip meter. To reset your trip meter look for a knob or button near your odometer. The trip meter is used to measure the distance of a particular trip. If your car or truck isn’t equipped with a trip meter, just write down the mileage on your odometer after you fill the gas tank.
2. Drive your vehicle until about three quarters of the gas has been used up. I don't recommend letting your gas gauge get below a quarter of a tank. This may pull sediment up into your engine and cause problems.
3. Go to the gas station and fill the gas tank back up to full. Before you leave the gas station record the numbers you need to make your calculation. First, write down how many gallons it took to fill your gas tank back up. Next, write down how many miles your trip meter recorded since you reset it. If you are not using a trip meter, refer to the previous odometer reading you wrote down. Then use that number and your current odometer reading to figure out how many miles you have traveled since then.
4. Now divide the number of miles you traveled by the gallons of fuel you have used.

Here is an example:  236 miles divided by 9.36 gallons = 25.21. That would mean your car gets a little over 25 miles per gallon.
