What is the best way to improve gas mileage in a Toyota RAV4?

I recently purchased a Toyota RAV4 and noticed that I'm not getting the best gas mileage. What are some tips to improve my fuel efficiency?

First, make sure your tires are properly inflated. Underinflated tires can decrease gas mileage. Second, avoid excessive idling and aggressive driving. Also, try to plan your routes to avoid heavy traffic. And finally, consider using a fuel additive to help improve your fuel economy.

Check your air filter regularly and replace it if it's dirty. A dirty air filter can restrict air flow to the engine, causing it to work harder and decreasing gas mileage. Also, limit your use of the air conditioning and try to combine errands to reduce the number of trips you take.
