If I could understand the chemical differences between these coolants, that would be a very useful link. I'm sure some of the smarties here can make sense of it. It doesn't have that new HCR-188c (not that I'd expect it to with that coolant being so new), nor does it have the ES-22a NiHaoMike was talking about.... but it's still a relevant stack of info. Thanks for posting this!
