What is the best way to improve fuel economy in an Audi A4?

I recently purchased an Audi A4 and am looking for ways to improve its fuel economy. Any tips or advice would be greatly appreciated.

One way to improve fuel economy in your Audi A4 is to make sure your tires are properly inflated. This can greatly impact your gas mileage and is an easy fix.

Another tip is to avoid excessive idling and quick accelerations. This can waste fuel and put unnecessary strain on your car's engine.

Regular maintenance, such as oil changes and air filter replacements, can also help improve fuel economy in the long run.
