What type of oil should I use for my Audi 80's engine?

I recently purchased a used Audi 80 and am unsure about what type of oil I should use for its engine. Can anyone provide a helpful recommendation based on their own experience?

I recommend using a full synthetic oil, such as Mobil 1 or Castrol Edge, for your Audi 80's engine. These oils provide better engine protection and performance compared to conventional oils.

Based on my experience, I suggest using a high mileage oil if your Audi 80 has over 75,000 miles on it. These oils are designed to help reduce wear and tear on older engines.
