Understanding how to calculate gas mileage is crucial for managing your fuel expenses and optimizing your vehicle's efficiency. With fuel prices continually rising, knowing your car's fuel consumption can help you save money and reduce your environmental footprint.

Why Knowing Your Gas Mileage Matters

Calculating your gas mileage is not just about saving money; it's about understanding your vehicle's performance and making informed decisions.

By improving your gas mileage, you can significantly cut down on these costs.

Steps to Calculate Your Gas Mileage

1. Keep a Fuel Log

Start by maintaining a detailed log of your fuel usage. Use a notebook or a mobile app to record the amount of gas you fill and the miles you travel. This habit will provide you with the data needed to calculate your gas mileage accurately.

2. Fill Up Your Tank

When you fill up your tank, note the number of gallons you add and reset your trip meter to zero. If your car has a digital console, refer to the manual for instructions on resetting the meter.

3. Record Your Odometer Reading

At your next fill-up, record the odometer reading. Subtract the initial reading from this new reading to determine the number of miles driven since your last fill-up.

4. Calculate Miles Per Gallon (MPG)

Divide the number of miles driven by the number of gallons used. This will give you your car's miles per gallon (MPG). For example, if you drove 300 miles and used 10 gallons of gas, your MPG would be 30.
