I have to say, I'm pleased as can be with this report. Pushed it further than I ever have, used a stout Euro oil that is also CAT friendly, and came back with great metals, good visc, no issues with fuel or filtration, and plenty of TBN left over. Everything is below universal averages on a PPM/1000 mi scope (universal avgs based on 4100 miles). Some carryover from the previous oil is skewing the results. Running the same oil now and expect to see higher viscosity on next UOA (virgin viscosity is 11.92).
