What is the proper oil viscosity for a 1992 Audi 80?

I recently purchased a 1992 Audi 80 and I'm unsure of what oil viscosity to use. Can someone provide some guidance on the recommended oil viscosity for this specific model and year?

The recommended oil viscosity for a 1992 Audi 80 is 10W-40. This is because it provides a good balance between protection and fuel economy. However, you can also use 5W-40 for colder climates or 15W-40 for hotter climates.

I've had great results with using a synthetic 5W-30 oil in my 1992 Audi 80. It provides excellent protection and improved fuel efficiency.

I recommend sticking with the manufacturer's recommendation of 10W-40 for your 1992 Audi 80. It's what they designed the engine to run with and will provide the best performance and longevity.
