tj5450,
You may try calling the the lab who performed this UOA to see if they can re-run the TBN,
they may still have the sample in their lab,
I have read some other UOA threads where the customer called the lab to have the oil re-tested because of questionable information,
it is possible the TBN testing apparratus was set-up incorrectly.
Blackstone had some questionable UOAs last Spring and they stated so after they were called upon, good luck with your oil
