Really, with the lack of any sort of controls on vehicle operation there is no way to correlate elevated wear metal reports to the oil. Never is it a variation between (for example) 10ppm and 350ppm which might show something significant. No one here has ever shown anything that indicates the relatively minor differences are in any way significant.
This.
We are talking relatively minor variances in parts per million in conditions that are anything but controlled using a tool that isn't designed for the purpose of comparing lubricants. Trying to divine anything significant out of that circumstance is utterly futile.
