How often should I change the oil in my Audi A8?

I just purchased an Audi A8 and want to make sure I am taking good care of it. How often do I need to change the oil to ensure my car's engine stays in top condition?

It is recommended to change the oil in your Audi A8 every 10,000 miles or once a year, whichever comes first.

If you frequently drive in stop-and-go traffic or harsh conditions, consider changing the oil every 5,000 miles for better engine performance.
