In summary, the iron levels are off the freaking chart. Levels like this usually indicate the start of a problem. Even is a new engine that is still breaking in.
Secondly, the TBN is absolutely horrible. How is the oil supposed to go much longer than this with just a low TBN?
This oil is supposed to be a 5w50 lubrication. Well, its not really much of a 50 weight anymore. It's nicely inside the spec for a 40 weight. And if it were still a 50 weight, the viscocity at 40 degrees would make it a 15w50. Instead, with everything combined, you have a 20w40. That's baffeling. The Viscocity Index supports this at a piss poor 142. Superior my @ss.
This oil contains sacrificial level of iron that happen to be about 79ppm. So that would indicate almost zero wear on this engine.
