After reading those threads, I am convinced that this is a snake oil idea.
First of all, using it has no benefits. It takes 1500km before you "notice anything", which is a huge belly-laugh all by itself. No power gains, no other gains outside of some psychological "wishing that it does something, but not sure what". So, I'm wondering what all the fuss is about, since nobody is really seeing any kind of gain that they can verify, but they seem very enthralled with the idea of using it, for some reason unknown to anyone else. This puts it firmly in the "wishful thinking" category.
One thing that stuck out was the recommendation to change the oil filter after 250km because "it cleans out the muck from the engine". I suspect that it is not "cleaning out" any muck, but it IS the muck that you just put into your engine, and it clogs the filter.
The other thing is this idea of "over-lubrication" causing a slipping clutch. It is more likely that these granules in the oil is preventing full contact of the clutch plates, thereby ruining clutch holding.
So basically, this is a "treatment" for oil that doesn't do any good, and causes problems.
Great!
