so i was watching Truck U on the speed chanel w/ my buddy and they were showing this stuff called Zmax. it is saposed 2 soak into the metel in your engine and transmition 2 decrease friction. i'm going 2 pick this up next pay check and see how it works in the engine and trans. it says it increases engine life, gets rid of carbon build ups, lubricates the engine at start up even befor the oil gets 2 it. and it says that it loweres friction so much that there is a gein in HP. anyone else seen or tried this?
