i swear by it!!! and that powerblock show had more than just the oil. it was a camaro (i believe) and they swapped out ALL the fluids/lubes with royal purple brand. they dynoed the car before and after the royal purple treatment, and it literally had almost 10 more hp just from all the Royal Purple brand lubes. That...and the fact that a few of my buddies who are mechanics use the stuff...convinced me to try it and so far, I loove it. might even try the tranny fluid. i'm gettin desperate with the 3rd gear troubles
