What is the best way to maintain the engine of my Audi A4?

I have recently purchased a new Audi A4 and I want to make sure that I properly maintain the engine to ensure its longevity. What are the recommended maintenance steps for the engine of an Audi A4 and how often should these be performed?

Regular oil changes are crucial for maintaining the health and performance of your Audi A4's engine. I recommend changing the oil every 5,000 miles.

In addition to regular oil changes, make sure to also check and replace your air filter regularly. A clogged air filter can impact the engine's performance and lead to higher fuel consumption.
