comments: data flagged for observation only;abrasives(silicon/dirt)are at a minor level;copper is at a minor level;bushing/thrust metal and/or most of the copper may be from lube cooler(as applicable);viscosity is slightly low;please provide unit manufacturer/model in order to compare data to proper standars for this unit;lubricant change acknowledged.

my comments:did provide lab w/ manf/model,they addmitted to missing.
so i dont really think silicon/copper is at a minor level for this engine/mileage????

 

where did u get your analysys done? I would say that not a bad composition and pretty much avaerage from what I have seen. The next few will be more telling.
