How to properly maintain my Audi engine?

I recently purchased an Audi and I want to make sure I am taking proper care of the engine. What routine maintenance should I be doing and how often?

For the best engine performance, it is recommended to follow Audi's recommended service schedule. This includes regular oil changes, air filter changes, and spark plug replacements.

I also suggest checking your coolant levels and having a coolant flush every 2-3 years. This will help prevent any overheating issues.
