It has a bad rap because most didn't even think of using it until it smoked blue ... as in "that motor is shot".


Actually it has a bad reputation because as I said, it is literally liquid plastic in a can. Using it changed the formulation of the oil by a wide margin.

I pay for a quality oil, not something I have to add a supplement to, not knowing what it does to the host oil without testing it.
