How to increase the fuel efficiency of my Volkswagen Golf?

I recently bought a used Volkswagen Golf, and while I love the car, I've noticed that it's not as fuel efficient as I expected. Are there any tips or tricks I can try to improve its fuel efficiency?

One way to increase the fuel efficiency of your Volkswagen Golf is to make sure you regularly maintain and service your car. This includes keeping up with oil changes, changing air filters, and checking tire pressure.

Another tip is to avoid excessive idling and aggressive driving. Try to accelerate and brake smoothly, and turn off your engine if you'll be stopped for more than 30 seconds.

To further improve your fuel efficiency, you can also try using cruise control on the highway and removing any unnecessary weight from your car. Every little bit helps!
