What is the recommended oil type and capacity for an Audi 80?

I am planning to change the oil in my Audi 80 and want to make sure I use the correct type and amount of oil. Can anyone provide recommendations for the specific type of oil, as well as the appropriate amount to use in my vehicle?

According to Audi's official recommendation, the best oil type for an Audi 80 is a fully synthetic oil with a viscosity of 5W-30. As for the capacity, it varies depending on the engine size, but for most models it is approximately 4.5 liters.
