How can I improve my Volkswagen Polo's fuel efficiency?

I recently purchased a Volkswagen Polo and I noticed that it doesn't get the best gas mileage. What can I do to improve its fuel efficiency?

Regularly check your tire pressure and make sure it's at the right level. Under-inflated tires can decrease fuel efficiency.

Avoid aggressive driving, such as speeding and rapid acceleration. This can greatly impact your fuel efficiency.

Make sure to get regular tune-ups and oil changes. This can keep your engine running smoothly and improve fuel efficiency.
