From the information gathered, it looks like the coolant is about 70 percent ethylene glycol and 30 percent propylene glycol. The manufacturer says there can be up to 3 percent water content before the boiling point drops.
I would probably use the manufactured product myself. Besides the whole warranty factor, it seems like they provide lots of free tech support and advice to those who ask nicely. If the vehicle had anything strange going on after the change, I wouldn't just be wandering around in the dark changing cooling system components. Not to mention that modern, fuel injected vehicles are computer tuned for "normal" coolant, and would certainly rebel against the higher temperature ceiling.
