the green stuff tends to be corrosive if not changed on a regular basis. also you tend to get an anode type corrosion from flow of liquid over a metal surface...i suppose grounding the metal core would keep alot of this from happening, but still the green is corrosive. the orange isnt from what ive understood, and you can run it 100% instead of having to water down glycol antifreeze do to its corrosiveness


just my .02 anyone got anything else?
