As others said, it has pluses and minuses. Worst is it has a lower specific heat than water or anti-freeze and therefore will not remove heat as well from the engine. Thus if you have overheating issues they will be made worse. A lot of people think this stuff will cure a fundamental issue with the cooling system, not so.

Stuff is expensive, a pain to get in there (must remove all old coolant) and if you happen to have a leak you would have to carry more of the expensive stuff, or if you topped it off with something else, would require complete flush.

For cars that don't move, its good because there are no corrosion issues.
