And my point is, both of those add power, if you look at at the links, the royal purple has been shown to add 7 or so HP on dynos, and more importantly, at a lower RPM. That is the point, if you do something that adds performance (more HP at a lower RPM for example), it is not longer in contention to be "stock"
