Below is my 2nd UOA on this vehicle. The first UOA recommended I extend the OCI out to about 5k miles, which I did. Since that was 25% longer than the 1st OCI, I expected slightly more wear, and some were a tad higher. I also ordered a TBN on this UOA. At 2.2, I'm thinking I don't want to push it much longer - do you guys agree? Blackstone didn't comment on the TBN, so don't know what to make of that. The only other item that concerned me even a little was the Silicon, which was higher than last time, but still not too bad IMO. As usual, all comments appreciated.
