How do I increase my Toyota Yaris' fuel efficiency?

I recently bought a Toyota Yaris and I noticed that it consumes a lot of fuel. Can you give me some tips on how I can increase its fuel efficiency?

One way to increase your Toyota Yaris' fuel efficiency is to regularly maintain and service your car. This includes changing your air filter, oil, and spark plugs.

Maintaining a steady speed while driving and avoiding aggressive acceleration and braking can also improve your car's fuel efficiency.

Consider using a fuel additive to clean your fuel system and improve your car's performance.

Avoid carrying unnecessary weight in your car, as this can also contribute to lower fuel efficiency.
