What is the best motor oil type for a 1990 Audi 80?

I am looking for recommendations on the best type and brand of motor oil to use in my 1990 Audi 80. I want to ensure proper engine protection and longevity.

According to Audi's official recommendations, the best motor oil type for a 1990 Audi 80 is a 5W-30 fully synthetic oil with an API rating of SN. It is important to use a high-quality synthetic oil for optimal engine performance.

I highly recommend using a European car specific oil, such as Castrol EDGE 5W-30, for your Audi 80. These oils are specially designed to meet the needs of high-performance European cars.

As a long-time Audi owner, I have found that Mobil 1 0W-40 works exceptionally well in my 1990 Audi 80. It provides excellent engine protection and is affordable compared to other synthetic oils on the market.
