Which engine oil is best for the Audi 80?

I have recently purchased an Audi 80 and am looking for the best engine oil to use. Can someone recommend a specific brand or type that would be most suitable for this car?

I recommend using Castrol Edge 5W-30 for your Audi 80. It is a fully synthetic oil that provides excellent protection for your engine, especially in extreme temperatures.

I have been using Mobil 1 0W-40 in my Audi 80 for the past year and have seen a noticeable improvement in performance. It is a bit pricier but worth it in my opinion.

If you are looking for a more budget-friendly option, I would suggest Shell Helix HX7 5W-40. It is a good quality semi-synthetic oil that still provides good protection and performance.
