How to properly maintain and clean the engine of an Audi A1?

I've recently purchased an Audi A1 and I want to make sure I take proper care of its engine to ensure it runs smoothly for years to come. Can someone guide me on the best practices for maintaining and cleaning the engine?

The most important step for maintaining your Audi A1's engine is to regularly change the oil and oil filter. This will help keep the engine clean and prevent buildup of harmful contaminants.

Make sure to also check the air filter and replace it if it's dirty. A clean air filter will help improve engine performance and fuel efficiency.
