The Edge OE UOA posted above came back pretty darn good, and I recall one with M1 ESP that was pretty good too. Maybe Amsoil's formula just isn't up to the standards of the majors in this case.
What's odd is how different this UOA is from the last one 1wrxtra posted.
What were the exact conditions of collection from the used oil pan? I would expect some contamination with debris, but I wouldn't expect the KV100 to be affected unless there was other oil already in the pan.
This most recent sample (the Amsoil 5w30 I posted above in post #92) I took correctly so those results should be correct unless Blackstone fudged something up. The previous test (the second UOA in post #69) was sampled from the pan. It was a new pan though, had never been used before that so it wasn't contaminated from old oil.
Was that what you were looking for or did I misunderstand your question?
