They are advertising it as a Universal top off, so are you saying that's not true?

Hi,

No, it's not true. This is an ethylene-glycol based OAT Coolant, and so while it is OK for the Porsche (But only the Global Lifetime and Sierra - no other Peak products are compatible), it is not acceptable for some types of Cooling systems.

Peak makes several products and I don't want to start OK'ing Brands here because someone will invariably use the Peak Blue, or some such, and this is bad for the car.

What you want is a Coolant which is Silicate and Phosphate Free and is either G 12 (G 30 in Europe) or G 34...

Happy Motoring!... Jim'99
