How do I make my Volkswagen Polo more fuel efficient?

I have been driving my Volkswagen Polo for a year now and I have noticed that it consumes a lot of fuel. How can I improve its fuel efficiency?

Regularly maintain your vehicle and replace any damaged or clogged filters to improve fuel efficiency.

Avoid aggressive driving, such as sudden acceleration and braking, as it can significantly impact fuel efficiency.

Consider using cruise control on highways to maintain a consistent speed and save fuel.
