How to improve the gas mileage on a Volkswagen Golf?

I recently purchased a Volkswagen Golf and it seems to be using a lot of gas. Is there anything I can do to improve the gas mileage on my car?

First and foremost, make sure your tires are properly inflated. Underinflated tires can greatly decrease your gas mileage.

Another tip is to drive at a consistent speed and avoid aggressive driving. Rapid acceleration and braking can use up more gas than necessary.

Regularly changing your air filter can also improve your gas mileage. A dirty air filter can obstruct airflow and make your engine work harder.
