Beats me I have heard both arguments some say waste of money, does nothing, others swear by it. I have never used it myself. I don't know about that stuff but we did an experiment with Slick 50 in Auto mechanics class in vo-tech. We ran it through a lawn mower engine then drained all the oil and cut a hole on the crankcase. Bolted in a lexan window and ran it dry. It was still running when I graduated.

I learned all I need to know about life by killing smart people and eating their brains.
