Refill your tank and note the amount of fuel you added.

Once you've driven until your tank is nearly empty, it's time to refill it and note the amount of fuel you added. This information is essential for calculating your gas mileage.

Here are the steps to follow:

  1. Choose a reputable gas station.
    Make sure you're filling up at a gas station that sells high-quality fuel. This will help ensure that your vehicle is getting the most efficient fuel possible.
  2. Fill up your tank completely.
    When you're filling up your tank, make sure to fill it all the way to the top. This will give you the most accurate reading of your gas mileage.
  3. Pay for your fuel.
    Once you've filled up your tank, pay for your fuel. Be sure to keep your receipt.
  4. Note the amount of fuel you added.
    After you've paid for your fuel, check the receipt to see how many gallons of fuel you added to your tank.

It's important to note the amount of fuel you added accurately. This information is essential for calculating your gas mileage.

Once you've noted the amount of fuel you added, you're ready to calculate your gas mileage.

Divide the miles driven by the gallons of fuel used.

Once you have the number of miles you drove and the number of gallons of fuel you used, you can calculate your gas mileage by dividing the miles driven by the gallons of fuel used.

  • Write down the formula.
    The formula for calculating gas mileage is:

    Gas Mileage = Miles Driven ÷ Gallons of Fuel Used

  • Plug in your numbers.
    Replace "Miles Driven" with the number of miles you drove and "Gallons of Fuel Used" with the number of gallons of fuel you used. For example, if you drove 300 miles and used 10 gallons of fuel, your formula would look like this:

    Gas Mileage = 300 miles ÷ 10 gallons

  • Calculate your gas mileage.
    Divide the number of miles driven by the number of gallons of fuel used. In our example, 300 miles ÷ 10 gallons = 30 MPG. This means that your vehicle gets 30 miles per gallon of fuel.
  • Understand your gas mileage.
    Once you've calculated your gas mileage, you can use this information to understand how fuel-efficient your vehicle is. A higher MPG means that your vehicle is more fuel-efficient and costs less to operate. A lower MPG means that your vehicle is less fuel-efficient and costs more to operate.

By following these steps, you can easily calculate your gas mileage and gain valuable insights into your vehicle's performance.

The result is your MPG.

Once you've divided the miles driven by the gallons of fuel used, the result is your MPG (miles per gallon). This number represents how many miles your vehicle can travel on a single gallon of fuel.

  • Understand your MPG.
    A higher MPG means that your vehicle is more fuel-efficient and costs less to operate. A lower MPG means that your vehicle is less fuel-efficient and costs more to operate.
  • Compare your MPG to other vehicles.
    You can use your MPG to compare the fuel efficiency of your vehicle to other similar vehicles. This information can be helpful when shopping for a new car or truck.
  • Use your MPG to track your fuel consumption.
    By keeping track of your MPG over time, you can identify any changes in your vehicle's fuel efficiency. This information can help you diagnose problems with your vehicle or make changes to your driving habits to improve your MPG.
