Molakule has also changed his tune a bit about moly. He said that there's industry info stating that moly isn't being thought of as an anti-wear additive any longer. Only as a friction modifier. This wasn't in the White Papers section, but in a reply to a post IIRC.

I would have gone with Oil Analyzers Inc if you're getting this deep into it. For a cheaper price you get TBN, oxidation, nitration, and sometimes fuel reading by gas chromatography instead of the estimate that Blackstone does. Better yet, hire your own tribologist for the
best feedback to your wear questions.

In the article that I linked above by Doug Hillary, he cautions about reading too much into these cheap uoa's and using them as a tool to try to compare uoa wear with actual engine wear (teardowns and measurements are the best way to do that).
Here are some graphs that Terry Dyson did for an STLE conference when he was working with RS4 owners and Renewable Lubricants Inc. to develop an oil that performed better than VW502 oils.

Unfortunately, no high mileage stuff there.
Doug Hillary would probably be able to answer your questions, although he doesn't post very much at bitog these days. Terry Dyson can answer your questions, although it will cost you.
I pretty much gave up on uoa's after doing them religiously for about twelve years. As Doug Hillary said, they're better to determine the condition of the lubricant (or maybe to alert you of an obvious problem), but they're not
always useful for predicting impending failure. I blew a turbo with good uoa's. Don't think too hard about this. You'll hurt your brain.
