But with a 1000 mile oci, how bad would wear need to be to observe it.
With an average vehicle, with average oil, and an average driving style, one may expect to see 4 ppm of iron per 1000 miles per 5 quarts of oil -just as an example. So, if this OCI had average wear, with a 3X sump, you may expect to see 1 ppm iron. Throw in a little measurement error and leftover wear material from the previous OC and perhaps you would see 0 to 5 ppm iron. From this report, your wear could be zero, average, or something above average and you would not be able to differentiate the three options. The same rationale could be used for lead, copper, etc.
I am appreciative that you have shared your results, but the only conclusion that I can find is that you are not experiencing catastrophic failure or accelerated wear. I cannot find a way to leap to the conclusion that your current fill is any better than an average conventional from this particular data. Perhaps a valid conclusion is that two years in the sump is not a problem in your environment.
Please continue to share your results even if some of us can't yet find a way to draw any conclusions.
