Harrtig,
To start off with an 180 degree thermostat won't open until that temp. and all you have is a small flow of water through the bypass hose,which will bring most engines up to temp pretty quick. That is all the thermostat is for, it has nothing at all to do with determinging what your engine will run at when driving. Listen to what Turk said. He did the tests and they proved the same as most of the other tests results I have seen in car magazines.
Rick,
Where did you get the Super Water wetter? I can't find it up here at any of our auto stores but haven't checked the two largest ones yet. NAPA out here claims they never heard of it.
