How do I extend the lifespan of my Audi A4's engine performance?

I recently purchased an Audi A4 and I want to make sure that the engine performance lasts for as long as possible. Are there any maintenance tips or techniques I can follow to keep the engine running smoothly for years to come?

Regularly change the oil and oil filter. This will help keep the engine clean and prevent any buildup of debris.

Check the air filter and replace it if necessary. A clogged air filter can restrict air flow and put added strain on the engine.
