Just got this sample back after doing the EGR delete the best thing one can do to this engine, before the delete soot was much higher,wear metals are much better this time around also the T6 oil seemed to hold up well visc still within range TBN showing strong yet,going to do 15,000 then recheck.
one thing i noticed was Cal. must be lab error? at only 815.
