What is the recommended coolant blend for an Audi 80?

I recently acquired an Audi 80 and was wondering what blend of coolant would be most suitable for optimal performance and longevity. I live in a colder climate, so I want to ensure proper protection against freezing temperatures as well.

The recommended coolant blend for Audi 80s in colder climates is a 50/50 mixture of antifreeze and distilled water. This will provide adequate protection against freezing temperatures while also ensuring proper levels of corrosion and rust inhibitors for optimal performance and longevity.

I have had success using a pre-mixed coolant specifically designed for German car models like the Audi 80. These types of coolants are often formulated with the ideal blend of additives and inhibitors for maximum protection and longevity in your specific vehicle.
