How to maintain the Toyota RAV4's fuel efficiency?

I recently bought a Toyota RAV4 and I'm worried about the fuel efficiency. What are some ways to maintain its fuel efficiency?

First, make sure to regularly change the air filter and spark plugs as these can significantly impact fuel efficiency. Also, try to avoid idling for long periods of time and maintain a steady speed while driving.

Additionally, keeping your tires properly inflated can also improve fuel efficiency. And try to plan your trips efficiently to avoid unnecessary driving.

You can also consider using fuel additives or switching to a higher grade of gasoline for better fuel efficiency. But always consult your owner's manual before making any changes.
