Same as oil choice.

Coolants have different levels of PH (acid), Silicates, Sulphates, Borates and other additives. Each manufacturer specifies a formulation suitable for the metals in the engine, rubber hoses, seals etc.

Nothing to do with whether it mix, perform better, "price", or anything like that (geez guys). Since I don;t own a test lab, and know clap about coolants and the materials used in our engine, I am going to stick to what Porsche Eng recommends
