How to increase the fuel efficiency of a Volkswagen Golf?

I recently bought a used Volkswagen Golf and I noticed that the fuel efficiency is not as good as I expected. Are there any tips or tricks I can use to improve the fuel efficiency of my car?

Properly inflated tires can also make a big difference in fuel efficiency. Check your tire pressure regularly and make sure they are inflated to the recommended PSI for your Volkswagen Golf.

First and foremost, make sure to regularly maintain your car by getting it serviced and changing the oil and air filter according to the manufacturer's recommendations. This can greatly improve fuel efficiency.

Another important factor is driving habits. Avoid aggressive driving, such as quick accelerations and hard braking, as this can significantly decrease fuel efficiency. Also, try to maintain a consistent speed while on the highway.
