How often should I change Audi A6's engine oil?

I have recently purchased a used Audi A6 and I want to make sure that I give it the proper maintenance. I was wondering how often do I need to change its engine oil to keep it running smoothly?

It is recommended to change your Audi A6's engine oil every 5,000 to 7,500 miles. However, if you frequently drive in harsh conditions such as extreme temperatures or dusty environments, it is best to change it more often, around every 3,000 to 5,000 miles.

Personally, I change my Audi A6's engine oil every 5,000 miles to ensure optimal performance. But it is always best to refer to your vehicle's manual and follow the manufacturer's recommendations for your specific model.

I've been a mechanic for 10 years and I can say with confidence that changing your Audi A6's engine oil every 5,000 miles is the best way to maintain its health and longevity.
