What engine oil is recommended for an Audi 80?

I am planning on changing my engine oil for my Audi 80. What is the best type and brand of oil to use, and when should it be changed?

For your Audi 80, we recommend using a fully synthetic 5W-40 engine oil such as Castrol EDGE. This will provide optimal protection and performance for your engine. It is also important to follow your vehicle's recommended oil change intervals, which vary depending on your driving habits and driving conditions.

As a mechanic, I have seen many Audi 80s come through with various engine issues. To keep your engine running smoothly, it is crucial to use a high-quality engine oil, such as Mobil 1, and change it every 5,000 miles or 6 months, whichever comes first.
