DEI Radiator Relief it clames to lower operating temps and shorten warm up time ect I do not trust this has any one tried it or find an article that tests this the page telling about it is here http://jscspeed.com/universal/fluids/dei_radrelief.htm

seems like it conflicts with itself. I dont see how it can warm up faster AND keep your engine colder. Warming up faster would imply that it has a lower specific heat (takes less energy to raise temp), but keeping the engine cooler would imply a higher specific heat. Anyone else thinking the same way?

That was what I was thinking I just havent found any actual info on it. Would any one know about Redline Water Wetter i have not had time to look up info on it yet.

Well, if it really does lower operating temps by 30 (which it won't because of the thermostat), it'll reach that temp quicker than it would have reached the higher temp. It doesn't warm up quicker, that is contradictory to the cooler claim, won't happen, it'* governed by thermodynamics. It just reaches it'* equilibrium temp faster, because it'* lower.

I've used the Redline stuff before. It did lower city temps by 5 to 10 degrees, but on the highway it dropped to the thermo temp like normal.

i was waiting for someone who knew more chem than me to chime in. Ahhh, good ol' thermodynamics.
