Porsche uses Elf Glacelf Supra OAT coolant and rebadges it. It's meant to be mixed with distilled water like all other coolants.
It's incompatible with traditional coolants and will form a gel that will not flow and is difficult to clean out.
Dexcool coolants from Texaco are compatible. But I'm not making promises.
