Great stuff... I now have a minor in coolantology. But here is the catch - the reason to use porsche coolant (or Dex-Cool) is to make sure it matches the OEM coolant already there. BUT, on my inspection there was green coolant in the tank.
So clearly not the pink porsche coolant - but what is it?

Is the Dex-Cool green? Any quesses?

So my conclusion is it is probably more important to get all the old green coolant out than what I put in afterward. The problem seems more to be mixing coolant types than what brand you put in. (Havoline, Chevon and Zerex all market Dex-Cool.)
