How to Calculate Gas Mileage

Your gas mileage can vary based on a number of factors, but your specific make and model has an EPA-estimated gas mileage rating. Learn how to calculate gas mileage with us as we go over a general and easy way to measure your vehicle’s fuel efficiency. And afterward, explore our service and parts specials for any needed maintenance on your Chevrolet vehicle!

What is Good Gas Mileage For Your Car?

If you have a sedan, you’ll have different gas mileage expectations compared to a truck or SUV. Larger vehicles generally require more energy to run, and options like hybrids generally have better fuel economies compared to just gas-powered cars.

To figure out what good gas mileage is for your vehicle, we recommend checking your specific make and model’s fuel ratings, especially compared to other model years for the same vehicle or the fuel ratings for other vehicles in the same class for your model year.

If you’re not getting the gas mileage that your make and model is supposed to be getting, your vehicle may need new tires, an oil change, or other common maintenance services to improve those mpg ratings.

Gas Mileage Calculator

We have a general gas mileage calculator for Oceanside and Poway drivers below:

1. Read your owner’s manual to find out how much gas your tank holds. Fill your gas tank completely and reset your trip odometer or record the exact mileage after refilling your vehicle.
2. Drive your car as you would normally and note if you drive any differently than usual. Your mileage may vary based on how your drive, and any changes in your driving behavior can change your mpg ratings.
3. Drive until your tank is low– but not too low to trigger a low tank notification– and refill your tank completely. Make note of how many gallons you added to your tank. Waiting to refill until your tank is lower will give you a more accurate reading thanks to a probable mix of different driving conditions.
4. Divide the number of miles you’ve traveled by the number of gallons of gas your vehicle took to refill. This will be miles driven divided by the gallons of gas used.
5. You should now have your roughly calculated gas mileage.

Feel free to try this multiple times from start to finish to figure out an average for your vehicle. If you forget to check how many gallons you filled up your car at the pump, you can go by where your tank was when you refilled (i.e. ¼, ½, or ¾). Divide the total tank capacity to get the number of gallons refilled. Divide the miles driven by that approximation. This will be less accurate since the gas gauge in some cars isn’t always completely accurate. A digital gas gauge can be more accurate compared to older vehicles though.
