What is the best way to maintain the fuel efficiency in a Volkswagen Polo?

I recently bought a Volkswagen Polo and I want to make sure I am doing everything I can to keep its fuel efficiency at its peak. Can anyone offer any tips or tricks?

Regularly check and maintain the tire pressure to reduce rolling resistance and save fuel.

Avoid carrying unnecessary weight in the car as it can impact fuel efficiency. Empty out your trunk regularly.

Try to keep a consistent speed and avoid unnecessary acceleration and braking. This can help improve fuel efficiency.
