That was my point and it had nothing to do with either Doug or a shotgun.
Whether UOAs are a valid measurement of engine wear is another matter.
I think that they are, but that's another discussion.
UOAs can also predict some impending failures, as another member found with his BMW.
They certainly can be used for potentially predicting an impending failure, no argument there. And yes, the oil held up well, again, no argument, as TBN retention was good and there was nothing obviously wrong in the UOA (I believe I indicated all of this above).
However I think the UOA speaks more to the health of your engine, not the quality of Nextgen Maxlife, which is likely on-par with most other PCMO's in its category. Perhaps I came across a bit crass, and that was not my intention. The point I was trying to make was simply that the information we can glean from a UOA is limited. Therefore, arguing the merits or detractors of a product based on one isn't the best approach. There is quite a lot a UOA doesn't tell us about lubricant performance that something like a tear-down does.
Put another way, I don't think there is any evidence that would show us that NextGen is NOT an excellent product; a product as good as any other oil in its target market on the shelf.
We are not at odds here as to our view on the product, we simply don't agree on the weight of the data presented by a UOA, which in the big scheme of things is irrelevant to this thread for the most part
I apologize if I came across rudely
