I was on another thread (Product review) and they were talking about Royal Purple "ICE". They said it worked in helping keep the truck cooler.
I tried a search but didn't feel like sifting through pages of stuff. What is the general feel about this stuff? Does it work? Is it bad to mix it with Dex?

Did nothing for me , mixed OK , works better with water than coolant

dido on what carhauler said

As for lowering ECT, it was nil, maybe 2-3 degrees(attitude temp). Not worth the $$
