How do I increase the fuel efficiency in my Volkswagen T-Cross?

I recently purchased a Volkswagen T-Cross and I've noticed that the fuel efficiency isn't as good as I expected. Is there anything I can do to improve it?

One way to increase your fuel efficiency is to ensure that your car is properly maintained. This includes regularly checking and replacing your air filter, keeping your tires properly inflated, and getting regular oil changes.

You can also try adjusting your driving habits. Avoiding rapid acceleration and excessive idling can help improve your fuel efficiency.

Consider using a fuel additive, like a fuel system cleaner, to improve the performance of your engine and increase fuel efficiency.
