How to improve fuel efficiency on my new Volkswagen T-Roc?

I just bought a Volkswagen T-Roc and I'm concerned about the fuel efficiency. Are there any tips or tricks I can use to improve it?

Regularly check your tire pressure and keep them properly inflated. This can help improve your fuel efficiency.

Avoid idling for long periods of time. Turn off your engine if you're waiting for longer than a minute.

Try to maintain a steady speed while driving. Rapid acceleration and braking can decrease fuel efficiency.

Consider using a fuel additive to clean your engine and improve fuel efficiency.

Plan your trips efficiently to avoid unnecessary driving. This can also save you time and money.
