What is the recommended oil type for a 1990 Audi 80 Quattro?

I recently acquired a 1990 Audi 80 Quattro and need to perform an oil change. What type of oil should I use to ensure optimal performance and longevity of my engine?

The best oil for a 1990 Audi 80 Quattro is a high-quality synthetic blend with a viscosity of 5W-30. This will provide the necessary protection and lubrication for your engine, especially during cold starts and harsh temperatures.

I have been using a full synthetic 5W-40 oil in my 1990 Audi 80 Quattro for over 10 years now and have had no issues with engine performance or longevity. However, it is important to make sure the oil meets the specifications and standards recommended by Audi.
