What type of oil does the Audi 80 use?

I just bought a used Audi 80 and I'm not sure what type of oil to use for its engine. It's a 2.0 liter, 4 cylinder engine. Can anyone advise?

For your Audi 80's 2.0 liter engine, the manufacturer recommends using a synthetic 5W-40 motor oil. This type of oil offers better protection and performance for your engine.

As a mechanic who has worked on many Audi 80s, I suggest using a fully synthetic 5W-30 motor oil. It will provide better lubrication and protect your engine from wear and tear.
