How to Easily Calculate your Gas Mileage

Everyone wants to save gas these days. One of the simplest ways is to drive a well-tuned car. How do you know if your car needs a tune-up? If your gas mileage has decreased, a tune-up may be in order. Learn how to calculate your gas mileage in a few easy steps. All you need is a few numbers and a calculator.

Difficulty: Easy

Instructions

Things You'll Need:

• Paper
• Pencil or Pen
• Calculator

1. Next time you fill your gas tank, write down your odometer mileage. Or, you can set your trip meter to zero.

2. When you fill your tank again, record the number of gallons it took to fill the tank.

3. Record the new odometer mileage. If you had set your trip meter to zero, simple record the number and skip to Step 5.

4. Subtract the first odometer reading from the second odometer reading for the number of miles driven since the first fill-up.

5. Take the number of miles driven and divide it by the number of gallons it took for the second fill-up. This is your gas mileage.

6. Periodically check your gas mileage. If your mileage changes more than 10%, you may want to consider a tune-up.

Tips & Warnings

• When you compare your gas mileages, be sure to "compare apples to apples." Don't compare a week of highway driving to a week of city driving.
