With the low miles on this oil and the engine your results look great. Low wear and good filtration.

There isn't anything to worry about in that UOA. With so few miles on the truck it's amazing there isn't more lead and copper from break in, even iron is low for break in wear.

Thanks for posting this. Don't see all that much RT testing posted. I'm running this oil too in a variety of equipment and getting good test results. I had been running 4K OCI of my Ford (an '86 "Powersmoke") for a decade with good results and just upped the OCI to 5.5K, so we'll see. I think you could go at least 4K. You didn't list TBN, but based on my learning here, it's worth paying extra for that test... at least until you get your OCIs figured out. At 4K, mine was always still very high, 6 & 7 or better.
