How do I improve the fuel efficiency on my Audi A3?

I recently purchased a used Audi A3 and have noticed that the fuel efficiency isn't as good as I expected. Is there anything I can do to improve it?

One of the best ways to improve your Audi A3's fuel efficiency is to make sure you are properly maintaining your vehicle. This includes regular oil changes, checking and replacing air filters, and having your tires inflated to the correct pressure.

Another tip for improving fuel efficiency is to drive conservatively. Avoid aggressive acceleration and braking, and try to maintain a consistent speed while on the highway.
