How do I know when my Audi 80 needs an oil change?

I recently purchased an Audi 80 and I'm not sure how often I need to change the oil. Can someone provide guidance on how to determine when it's time for an oil change?

The best way to determine when your Audi 80 needs an oil change is to check the owner's manual. It will provide the recommended interval for oil changes based on your specific model and year.

In general, it's recommended to change your oil every 5,000-7,500 miles or every 6-12 months, whichever comes first. However, for optimal performance, it's best to follow the guidance in the owner's manual.
