BS has gotten pretty notorious lately of providing incorrect or inaccurate information. Quite a few people have needed to tell them to rerun the sample and gotten quite a bit differnt results.The 5.8 TBN and the add pack. In addition, according to Mobil documentation on their website, the PAO is all but gone as well. I expected more for a 20,000 mile oil. Now, as I said in that thread, I am hoping there are things that are not seen that make it as stellar as ever. I am running it right now, so far so good.
