Wanted to see how the oil was faring in my 6.9L diesel 2K after an overhaul. It was mostly upper end work, but I replace the rings, pistons (still std. bore) and bearings because I got them for free ( : < ). I am running a bypass system with a 10 um element (I have previously stated 5 um but forgot that I followed the advice of running a 10um if you expect a high level of junk... either cleaning up a dirty engine or after engine work).
I guess you could call this a test of the "factory fill," in this case Rotella 10W30 Triple Protection. The "factory" was me!
I am satisfied with how things are going and will leave this oil in to at least 4K, likely 5-6K, after which it will get Rotella T5, a full synthetic primary filter and a 3um bypass. OCI... TBD. Likely 10K minimum but I will sample at 5K intervals to be sure. I put 2K on this this truck in a year so I am cogitating on how I will factor that into my oil and filter OCI. I have run OCIs out to 3 years with no issues and good UOAs. This is one reason I am switching over to full syn media filters because I trust the media more that cellulose on an extended time OCI.
Left figure is this 2K test/ middle figure unit averages from this truck at 5K OCI with 135K miles/right figure is Blackstone's universal averages for 5K. Zero figures not listed.
