There are as many opinions on Anti-Freeze as there is oil! I recently flushed my system, replaced water pump, hoses etc. and used Porsche coolant. You can get it from Suncoast Porsche for $20 a gallon. While I have no doubt that other products work just as well I chose to use the OEM recommended coolant. As long as you don’t mix types you should be ok. However, if you didn’t buy the car new then you really have no way of knowing short of sending off a sample for analysis. And, at that cost, you might as well just replace the coolant. Hope this helps. B)

Coolant for your Porsche is pretty cut and dried. Only use a G-12 type coolant. If you don't want to pay the Porsche parts counter price for a gallon, then go on down to your VW dealer's parts counter and get it there.

Valvoline actually developed the G-12 with BASF.

zerex G-30(AKA VW G12) is only sold under private label, and not over-the-counter.

"Zerex ExtremeLife" is pretty much the same thing in my opinion.
