How to Calculate Gas Mileage

2021 Mercedes-Benz GLA SUV exterior

High prices at the gas pump got you thinking about gas mileage? Perhaps, you’re wondering if you should use a gas mileage calculator to figure out how much you need. But, what is considered good gas mileage for the type of car you drive on Marietta roads? With all these questions, it’s understandable why you want to make an informed choice when buying your next used car, so we’ve compiled the answers below.

How to Calculate Gas Mileage in 6 Steps

You don’t need an online gas mileage calculator to figure out what kind of gas mileage your car gets. That would involve just re-entering all the information you would have to jot down to do this yourself anyway. Besides, the math itself is simple. So, we’ve listed some simple steps below on how to calculate gas mileage:

  1. Completely fill your tank the next time you get gas.
  2. Either reset the trip odometer to zero or take note of the exact mileage on the main odometer.
  3. Drive as you normally would around the Sandy Springs area or beyond until you need to fill your tank again. The more gas you use before filling up, the more accurate your calculation will be.
  4. Again, fill the tank completely, taking note of exactly how many gallons it takes to fill the tank.
  5. Check your odometer to take note of how many miles you drove since the previous fill-up.
  6. Divide the miles driven by the number of gallons pumped at your last fill-up, or input all of the numbers you gathered from the steps above into an online gas mileage calculator.

What is Good Gas Mileage for Your Car?

How do you know if the gas mileage your car gets is good gas mileage? Here are some general figures:

  • Small compact cars should be able to get over 30 miles per gallon on the highway
  • Larger SUVs do well to get over 20 miles per gallon
  • Hybrids can get over 40 miles per gallon or more
  • Plug-in hybrids can reach the equivalent of nearly 100 miles per gallon
  • All-wheel drive vehicles are usually not quite as fuel-efficient as their 2WD counterparts 
  • Many models come with multiple engine options, and generally, the least powerful engine will also get the best gas mileage on our Kennesaw roads.
