How to Calculate Gas Mileage

The Environmental Protection Agency (EPA) rates new vehicles based on their fuel efficiency. A lot goes into these ratings. However, each vehicle comes with a disclaimer that says your actual mileage may vary. So, if you’re looking for a simple way to calculate your vehicle’s actual gas mileage on Wilmington and Newark roads, Land Rover Wilmington’s guide on how to calculate gas mileage can show you how.

What is Good Gas Mileage for Wilmington Roads?

There’s really no set standard for good gas mileage for your vehicle. If you’re shopping for an SUV, for instance, your gas mileage might be good compared to all other SUVs but not nearly as efficient as a compact car. The same is true for comparing compact gas-powered cars with gasoline-electric hybrids, as the latter will almost always be more efficient.

While purchasing or leasing a new vehicle, keep in mind what you expect your gas mileage to be. That figure will factor into the overall cost of ownership. Then research new vehicles or used vehicles that offer the mileage you require. Two things to note here are that newer cars generally get better gas mileage and following the owner manual’s maintenance schedule provides one way to ensure the vehicle’s gas mileage stays within acceptable levels.

Gas Mileage Calculator: Step-by-Step Guide

It’s easy to learn how to calculate gas mileage for your vehicle.

Here’s what you want to do:

1. Fill your gas tank completely, and either reset your trip odometer or record the exact mileage after refilling. Determine how much your gas 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 based on traffic or the route you take, 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. For example, you drove 400 miles and refilled your tank with 20 gallons of gas. That comes to 20 mpg.
5. If you forget to check how many gallons you filled up your car at the pump 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 the miles driven by that approximation. This will be less accurate since the gas gauge in some cars isn’t always 100% accurate. A digital gas gauge shows you exactly how many gallons of gas are in the tank, and they are much easier to figure out gas mileage than with an analog gauge.
6. Many modern vehicles have automatic gas mileage calculators using computer chips and software. Feel free to go by that guide as well as compare the results you find manually.
