How to Calculate Your Car’s Gas Mileage

2022 Hyundai Kona EV on City Street


While gas mileage ratings give you a good idea of how efficient a model may be, they are not always accurate as specified in disclaimers given by the Environmental Protection Agency or EPA. So if you’re wondering how efficient your drives in the Black Mountain area are actually, you will find Hyundai of Asheville’s gas mileage calculator handy. Learn about what’s considered good gas mileage before we teach you how to calculate your car’s gas mileage below!

What is Considered Good Gas Mileage or Fuel-Efficient?

There’s no set standard for what is “good” gas mileage. However, when you’re car shopping in Hendersonville, you will notice that the body size of the vehicle impacts its efficiency. For example, an SUV may have what’s considered solid mpg specs, but they are likely lower than those of a compact sedan. The same is true for comparing compact gas-powered cars with gasoline-electric hybrids in that hybrids are almost always more efficient, which is one of the main pros of choosing a hybrid model. Depending on what vehicle you’re looking for, you will want to consider what’s an ideal range for the type of vehicle you want.

Gas Mileage Calculator Step-by-Step Guide

Calculate the gas mileage in your vehicle by following these steps:

  1. Fill your gas tank fully and either reset your trip odometer or record the exact mileage after refilling. Be sure you also find out how much gas your tank holds by checking your vehicle’s owner’s manual.
  2. Drive your car as you would normally. Note that if you accelerate more briskly or slowly or drive differently, your “typical” calculated gas mileage may be different than what you record.
  3. Refill your tank and record your mileage. If you wait longer to refill, your calculation will be more accurate as it will be based on a more balanced mix of driving conditions.
  4. The easiest way to calculate your gas mileage is to simply divide the number of miles traveled by the number of gallons of gas your vehicle took to refill. In sum, that’s miles driven divided by gallons of gas used.
  5. If you forget to check how many gallons you filled up your car at the pump on on your gas receipt, you can go by where your tank was when you refilled (i.e. ¼, ½, or ¾) and then divide out your total tank capacity accordingly to come to the number of gallons refilled. Then, divide miles driven by that approximation. This will be less accurate since the gas gauge in some cars isn’t always 100% accurate. With a digital gas gauge that shows you exactly how many gallons of gas are in the tank, this is much easier than an analog gauge, though.
