How to improve the fuel efficiency of my Audi A2?

I own an Audi A2 and I feel like I'm spending too much on fuel. What can I do to improve the fuel efficiency of my car?

One of the most important things you can do is to properly maintain your car. Make sure you stick to the recommended maintenance schedule and keep your tires properly inflated.

Another way to improve fuel efficiency is to avoid idling. If you're going to be stopped for more than a minute, it's better to turn off your engine to save on fuel.
