How to properly maintain the engine of Audi A3?

I recently bought an Audi A3 and I want to make sure I am properly maintaining the engine to ensure it lasts. What should I be doing regularly to keep the engine in good condition?

First and foremost, make sure you are regularly changing the oil and oil filter according to the recommended schedule. This will help keep the engine clean and running smoothly. It's also a good idea to check the oil level periodically and top up if needed.
