Silicon levels were low 8-9 through out all tests. Zinc went from 1100 to 1500 last test with TBN 9.1
I received the last sample report much too late (glitch with Blackstone) and I now have several more thousand miles on oil. Blackstone advised dumping the oil. I just changed the oil, went back to 15/40 Rotella T and OEM full flow filters. I did this as I will make 2 quick changes of oil and filter and with a 3rd fresh oil and filter change sample after 3,000 miles. I went back to factory system as changing Amsoil full flow and bypass 3 times is too expensive.
Truck runs very well, no smoke or undue noise, blow by normal, turbo feels OK, no rubbing that I can see on compressor side.
Think I have a bearing(s) going?? Comments please.
Thanks,
