With gas prices at all-time highs and still rising, it’s important to know your mpg, and you can with a simple gas mileage calculator.
There are many simple gas mileage improvements you can make, but if you don’t know what you’re getting, it’s hard to measure your improvements. Even if you know ways to save on your mileage, you’ll never realize the difference you’ve made unless you know what you’re getting now.
Here’s a simple way to calculate gas mileage. The next time you fill up your tank, write down the odometer reading. If you have one, you can also set the trip meter in your car to zero.
Now, the next time you fill up your tank again, be sure to record your odometer reading or trip meter reading again, and at the same time record the exact amount of fuel you’ve purchased (“5.25 gallons,” for example).
You don’t need to have an empty tank before refilling, just make sure you record the exact amount of gas you have in your tank to get the correct gas mileage calculator result.
Next, you want to deduct the second odometer reading from the first reading you have, and you’ll get the distance you traveled when you did that previous fill.
Now take the total you just calculated and divide it by the number of gallons you recorded when you filled your tank the second time. The result will be the miles per gallon or mpg your car currently gets.
