Almost all tabulations and individual UOA's I've seen show Amsoil with about, if not the lowest Fe per mile. This UOA is just is not right.
Funny thing about UOA, spring coming, guy could put in any oil, drive differently, engine flushed out and get similar results - so what to think then? Or say, very different results?
Dunno, probably fat fingers if I had to guess. That debacle aside, 14ppm silicon didn't exactly raise red flags since it's used as a defoaming agent (and he did have the engine opened (not long ago)?) but tx for sharing the inside scoop that Ams uses none. So yeah, probably an ingress issue somewhere. The ratio of wear metals to silicon ppm still seems high from reports I've seen but what do I know...maybe that's more a function of this engine and the amount of fuel in the oil is having a (more) profound effect on the film strength, compounding the matter?? Either way I would not continue to use that oil/grade until the root cause is determined, like you suggested.
