Is it important to regularly change the oil in an Audi A6?

I recently purchased an Audi A6 and was wondering how often I should change the oil in order to keep my engine running smoothly and efficiently. I've heard mixed opinions on this topic and would appreciate some expert advice.

It is crucial to ensure that the Audi A6's oil is changed every 5,000 to 7,500 miles. This will keep your engine lubricated, minimize wear and tear, and help your car maintain its optimal performance.
