I've never done a UOA this early before in an engine's life, but thought I'd send it in to Blackstone out of curiosity. Needless to say, the numbers are alot better than I expected. I was a little skeptical of the low numbers at first, but after searching for other factory fill results here in the diesel UOA section, I don't think they're too out of line.

90% of my miles are long highway drives, 150-350 miles at a time.
No TBN because there is no way I'm paying Blackstone an extra $10 with only 1457 miles on the oil.
I had always heard that GM used Mobil Delvac 1300 Super as the factory fill, but the additives in this oil don't match any of the UOAs with Delvac 1300 on my previous truck, & this looks pretty weak to me for a HDEO.
