By gathering the necessary information and using the appropriate tools and devices, calculating gas mileage can be done accurately and efficiently.

Step-by-Step Calculation

Calculating gas mileage is a straightforward process that requires basic math skills. The following steps will guide you through the process:

Recording the Starting Mileage

The first step in calculating gas mileage is to record the starting mileage of your vehicle. This can be done by checking the odometer reading before you start driving. Make sure to write down the starting mileage in a safe and easily accessible place.

Recording the Ending Mileage

The next step is to record the ending mileage of your vehicle. This can be done by checking the odometer reading again once you have finished driving. Make sure to write down the ending mileage in the same place where you recorded the starting mileage.

Measuring Fuel Usage

The final step is to measure the amount of fuel used during the trip. This can be done by filling up the gas tank before and after the trip and recording the amount of fuel used. Alternatively, you can use the trip odometer and fuel gauge to estimate the amount of fuel used.

Once you have recorded the starting and ending mileage and measured the fuel usage, you can calculate your gas mileage using the following formula:

Gas Mileage = (Ending Mileage – Starting Mileage) / Fuel Used

For example, if your starting mileage was 50,000, your ending mileage was 50,300, and you used 10 gallons of fuel, your gas mileage would be:

Gas Mileage = (50,300 – 50,000) / 10 = 30 MPG

By following these simple steps, you can easily calculate your gas mileage and keep track of your vehicle’s fuel efficiency.

Calculating Gas Mileage

Calculating gas mileage is an essential part of maintaining a vehicle and keeping track of fuel costs. There are two primary methods for calculating gas mileage: the manual calculation method and using a gas mileage calculator.
