I suppose this is a mod of sorts.

Anyone used this stuff?

The Science:
Traditional water based coolants regularly cross the thermal boundary that separates efficient Nucleate Boiling (A) from inefficient Critical Heat Flux (CHF). Critical Heat Flux (CHF) is synonymous with the condition ?Departure from Nucleate Boiling? (DNB).


Now my middle name is cynic but doesnt that sound remarkably like the "Science" spouted by the eggheads in lab coats on commercials for womens anti-ageing and wrinkle dissapearing potions?

Any guesses as to what 95% of the volume of this waterless coolant consists of? :wink:

Err, no, it sounds like what happens when water gets bloody hot in an engine :-)

Approximately 69% ethylene glycol
Approximately 29% propylene glycol
2% Additive package

I will let you draw your own conclusions.

Interesting. Mind you ordinary anti-freeze is probably at least as toxic.

I remember back in the 80's a friend tried this. All I can say is I'm very supprised that they are still in business and even more supprised that the likes of Jay Leno, Practicle Classics, and Wheeler Dealers use this. After he had it in his car for 6 monthes he went back to the traditional stuff. Absolutely Hokus Pokus (my opinion) for the premium you pay for this stuff.

It has to have something in it. What are your conclusions?

I have seen the guys selling this 'stuff' at many an auto jumble. At first I was reasonably impressed by their sales spiel but after consideration I thought that if the boiling point is made artificially higher as they claim then this may well harm the engine. I believe that old cars have a way of telling you that things are wrong and boiling over is one of those warnings. If the car overheats there's something wrong with it that needs fixing.
