How to properly maintain and service my Audi's engine?

I have recently purchased an Audi and I want to make sure that its engine stays in top condition. What are some important things to keep in mind and how often should I service it?

Regular oil changes every 5,000-7,000 miles are crucial in preventing engine damage. Also, make sure to check and replace the air filter every 15,000 miles to improve engine performance.

In addition to regular oil changes, it's important to also check and replace the spark plugs every 30,000 miles. This will ensure proper ignition and prevent potential issues.
