How to improve fuel efficiency in a Volkswagen Polo?

I have recently purchased a Volkswagen Polo and noticed that the fuel efficiency is not as great as advertised. Do you have any tips or recommendations on how to improve the fuel efficiency? I currently drive mostly in the city with occasional highway trips.

One of the easiest ways to improve fuel efficiency in a Volkswagen Polo is to maintain proper tire pressure. Under-inflated tires can increase fuel consumption by up to 3%.

Avoiding aggressive driving can also greatly improve fuel efficiency. Accelerating slowly and smoothly, and maintaining a consistent speed can save you a lot of fuel.

Regular tune-ups and maintenance checks can also help improve fuel efficiency. Replace air filters and spark plugs as recommended by the manufacturer for optimal performance.
