So I mentioned that I was going to try to drive differently and see if I could improve my gas mileage. But if you don’t have a car computer that does it for you, how do you measure a car’s gas mileage. You probably know how already, but someone had to explain it to me, so in case you don’t know how I’m going to pass on the favor.To measure you’re car’s mileage, you’ll need a gas station, a calculator, and a notebook in your car. Here’s what you do:
- Go to the gas station, and fill your tank. Ideally, you want to fill it up to where the pump clicks off by itself so that you know it was filled up to about the same point. Write down how many miles your car has at the gas station. Let’s call this A.
- Drive!
- When your tank is nearly empty, go to the gas station. Again, fill it up to where it clicks, so you know it filled up to the same point. Write down how many miles you had. Let’s call this B. Then make a note of how many gallons you used. Let’s call this C.
- Now you’re ready to calculate your mileage. Just do the following calculation: Your mileage = (B-A) / C
Et Viola!
