ok this is just my 2 cents, Back when i worked for a shop we would use it to get the high hp hondas in the right temp. Using an aftermarket guage we would notice a 15-30 degree drop in temps. Its great stuff and i havent found anything as good. I have tryed redlines water weter and its not as good. I use it in my 6.0, the better halfs accord, and in my civic. Its great stufff.
