Which engine oil is suitable for an Audi 80 1.8L 4-cylinder engine?

I recently purchased an Audi 80 with a 1.8L 4-cylinder engine. I need to perform an oil change but I'm not sure what type of oil to use. Can anyone recommend a suitable engine oil for my car?

For your Audi 80 1.8L 4-cylinder engine, I would recommend using a fully synthetic 5W-40 engine oil. This type of oil is specially designed for high-performance engines and provides better protection against wear and tear.

I have the same car and I've been using a semi-synthetic 10W-40 engine oil for years without any issues. You can also go with a full synthetic option, but it may be more expensive.
