How to improve the fuel efficiency in my Audi A4?

I recently purchased an Audi A4 and have noticed it consumes more fuel than expected. How can I improve its fuel efficiency?

First, try to reduce your speed while driving. High speeds can cause your car to consume more fuel. Additionally, make sure your tires are properly inflated and your engine is well-maintained.

Another tip is to avoid idling for long periods of time. If you are waiting in your car, turn off the engine to save fuel. Also, avoid carrying unnecessary weight in your car as it can cause it to use more fuel.
