What is the best way to improve fuel efficiency in a Volkswagen Golf?

I drive a Volkswagen Golf and am looking for ways to save on gas. Any tips on maximizing fuel efficiency?

One of the easiest ways to improve fuel efficiency is to make sure your tires are properly inflated. Under-inflated tires can decrease gas mileage by up to 0.2% for every 1 psi drop in pressure.

Another tip is to avoid aggressive driving. Fast acceleration and hard braking can use up more gas than necessary. Try to maintain a steady speed and anticipate stops to save on fuel.

Regularly changing your air filter can also improve fuel efficiency. A clean air filter allows for better air flow, which can increase gas mileage by up to 10%.
