Consider using a fuel economy calculator to track your gas mileage and identify areas for improvement.

Regularly maintain and service your Toyota Camry, such as changing the air filter and oil, to ensure optimal gas mileage.

Try to minimize your use of air conditioning as it can decrease gas mileage.
