Considering the conditions and amount of time that it must have taken to accumulate the 38k km/ 24k miles, and running the PTO as well, I think the UOA seems quite reasonable. The filter looks like it survived the extended time as well (at least it's intact). Thanks for the pictures and the report itself.
Dustin,
I work and design bypass filters for the military and a few other applications.
1. Here's the truth, most bypass filters don't really do much.
2. If you delete the EGR and DPF, you don't need that filter. I have many customers that say but what if we put on a bypass filter? I tell them well you deleted DPF and EGR, there is little to no point.
On the 6.7PSD I routinely get 50,000 mile OCI's. I recently saw Terry Dyson bragging about 35,000 miles. PFFFFFt, that's a joke. I've gotten one PSD to 85,000 miles before we had to call it a day.

I believe that BP filters can do some very good work and show beneficial particulate reduction, but ONLY IF there's a massive amount of contamination to work with. For example, the bus-filter-study many of us have discussed here before; it showed a definite benefit to reducing particulate loading = less wear metals. HOWEVER, that study was run on 2-stroke diesel buses known for puking out tons of soot loading, etc. In a much-more-normal applications, where the soot loading is very low, and the added benefit of today's well-made lubes helps keep contaminants from amalgamating, filtration is kind of a waning necessity. I would not want to run an engine without filtration, but one does not "need" super-duper BP filters to sustain a reasonably clean sump.
Between the good lubes, clean running engines, decent FF filters, and a reasonable OCI, there's not really any tangible benefit to a BP unit. If you alter those inputs, then BP might be much more important to the equation. But not as most folks practice OFCIs today; it's not going to give any ROI.
