How to optimize the efficiency of the Audi A4's engine?

I recently purchased an Audi A4 and I'm wondering if there are any tips or tricks to improve its engine's performance and efficiency. It seems to be consuming more fuel than I expected. Any advice would be greatly appreciated.

There are a few things you can do to optimize your Audi A4's engine. First, make sure you are following the manufacturer's recommended maintenance schedule. This includes regular oil changes and tune-ups. You should also check the air filter and replace it if it is dirty or clogged. Additionally, driving at a steady speed and avoiding heavy acceleration can help improve fuel efficiency. You could also consider investing in high-quality fuel or using an aftermarket performance chip. These small changes can make a big difference in the long run.
