Waterless Coolant??

[Marcus]

At the risk of starting another of those "eye-rolling, here-we-go-again" threads (and by the way, I could not find any mention of this subject in the archives).........does anyone have any experience with the waterless coolants?? They claim to reduce / eliminate cavitation, localized hotspots, etc. Right now, I run a 50/50 mix of distilled water/coolant, but am intrigued by their claims. I know they are a bit more expensive, but that is not the question.
