Agree, very interesting. They seem to tout the high boil point as the main advantage, allowing engines to run with a higher coolant temp without boil-over. I don't want my coolant to be hotter than it is now. I'm on the edge of detonation as it is. Evans Q&A site says they typically run hotter than the same cooling system with a 50/50 water antifreeze mix. But if I could get the same heat transfer at near atmospheric pressure as I do with my coolant at 10 pounds I'd use it, if the thermal expansion wasn't so high that I would need a larger overflow tank. I think air in the cooling system causes a lot of the overheat problems. I'm not saying the stuff isn't any good but the magazines and Jay are paid to sell products so you kind of have to take their praise with a grain of salt. I may try some one day and compare it to the 50/50 mix I use now, if it works as advertised I'll be on this site hailing it myself.
