How to properly maintain the engine of my Audi A5?

I recently purchased an Audi A5 and want to make sure I am properly maintaining its engine for optimal performance. What steps should I take and how often should I do them?

Regularly check your engine oil level and change it according to the manufacturer's recommendations. This will ensure your engine is properly lubricated and reduces the risk of costly damages.

Don't forget to check and replace your air filter regularly. A clogged air filter can decrease engine performance and fuel efficiency.
