I've used it for a couple years. All the hype sounds good. I don't know of an advantage. Didn't notice any difference in it. That stuff is nasty though to get it on your hands. Their contingency program is ridiculous. It's promoted as a lifetime coolant yet you must buy a fairly large amount of it every two years to be eligible. If it's lifetime what are we to do with it?
