I was sceptical at first but with the quest of running cooler in warmer summer temps, I decided to try some.

I am almost anal about monitoring temperatures of just about everything so between using my infra red heat gun and various other temperature indicators have a pretty good idea of what is normal.

Temperatures have dropped by 15*F.
Of course, as soon as the car is stopped and idles for a while the temp goes back up 15*F but as soon as the airflow resumes, it drops back down.

This is very significant.
Has anyone else used this product :?:

Yep, I saw similar results, too. Haven't gotten any since my last coolant flush, though.

Ditto, great product, just don't ask me to explain how it works.

I saw not as good results but that was on basically water only anyways. I don't have a problem keeping my car at 160*.

I used it last year when my old intercooler heat exchanger placement caused the car to run hot. It helped keep the temps down. Since the new heat exchanger however I have not had a problem keeping the car cool without it.

I saw a slight change. I've noticed that it'* very sensitive to coolant mixture rates. It'* more effective without any coolant, but that brings up other dangers. I believe there'* a lifetime to it as well. It doesn't seem as effective now as it was a year ago.
