How can I improve gas mileage on my Toyota RAV4?

I am constantly having to fill up my gas tank and I feel like I'm spending too much money. I want to find ways to improve the gas mileage on my Toyota RAV4. What steps can I take to increase fuel efficiency?

Regularly check and replace your air filter to ensure proper airflow and fuel combustion. A dirty air filter can decrease gas mileage by up to 10%.

Avoid heavy acceleration and breaking, as this can greatly decrease gas mileage. Try to maintain a steady speed while driving.

Make sure your tires are properly inflated. Underinflated tires can decrease gas mileage and also wear out quicker.
