This is because Dexcool (aka Deathcool) was originally introduced without proper validation with all components for compatibility, killing elastomeric seals, gaskets, etc.
With above said, it works fine when the entire system is properly designed and validated for. Actually I use it exclusively with my 03 SAAB and no compatibility issues for 175K mikes and counting.
With my 986, I’m sticking with original Porsche coolant. Pricey but I did complete drain and refill shortly after my purchase 12K miles ago and I do not plan on changing it for at least 5 years so no big deal.
