What is the best oil type for my Audi 80?

I recently bought a used Audi 80 and want to make sure I am using the right type of oil. I've heard conflicting information and am not sure what is best for my car. Can anyone provide some guidance?

The best oil type for an Audi 80 is generally a high quality synthetic oil with a viscosity grade of 5W-30. This will ensure optimal performance and protection for your engine.

I've been using Mobil 1 synthetic oil in my Audi 80 for years and have had no issues. It's a bit more expensive but well worth the extra protection.
