Is the Porsche coolant a guaranteed thing, that's guaranteed to not cause compatibility issues? Assuming that your car is currently filled with factory coolant, absolutely. As has been pointed out, the issue is not in the coolant meeting proper specs, but in being fully compatible with whatever is currently in the system.

I don't think you can even buy coolant anymore, even the cheapest stuff around, that is not phosphate and silicone free, so is Prestone Dex-Cool acceptable? Certainly more than likely. Is the cheapest Walmart brand stuff probably fine too? Yup. Am I going to try either of these in my car? Nope.

If you do a complete flush, you can virtually run whatever you want in there. The key word there is complete. It will likely take 3 drain and fill with distilled water cycles to get everything out. I recently had to do this on my newest BMW, as when I purchased the car it had "standard" green coolant of unknown origin, and it took me 3 full drain and fill cycles until the water came out clear, without hints of green. Keep in mind also, that when doing this, you'll likely have to add a bit more coolant than water when you re-fill, as there will always be residual fluid left (the reason for the fill and drain cycles in the first place), which is now just water, not 50/50 mix.

If you're just topping off the system, I would save the hassle and just get the factory stuff. If doing a full drain and re-fill, you can save a little bit of money not buying factory coolant. At the end of the day, is all that hassle worth saving $20? Not to me.

Choice is yours; however, the last car we had in the shop that made the mistake of not using the OEM coolant (which can be purchased for $24/gal), cost its owner one Hell of a lot of money for us to clean out and repair................ So use whatever you please, but be aware of the consequences if you are wrong.................

We have to go on what we are told happened, and yes, we have been told that DexCool (and some other products) have been involved when the system "went oatmeal" on the owner............... That is why we keep telling people that the Porsche coolant is not all that expensive, so why do you even think about adding something else? If the system burps up and is low, just add water until you can get it properly cared for…………and don’t use “coolant additives” as they are unnecessary and you do not know what is going to happen when you put them in your cooling system……….

Just so I understand then, you've never had a customer state that they added only dex cool and had the coolant gel? You've only seen it when they added something else too?
