How to maintain good fuel efficiency in my Volkswagen Polo?

I recently bought a Volkswagen Polo and I want to make sure I am getting the best fuel efficiency possible. Can anyone give me some tips on how to maintain good fuel efficiency in my car?

Regularly check and replace your air filter to improve engine performance and increase fuel efficiency.

Avoid accelerating quickly and braking harshly, as both can lead to excessive fuel consumption.

Keep your tires properly inflated to reduce the amount of fuel your car needs to use.
