Got the Blackstone oil analysis in my email this evening and ran it by Deren for a second opinion. Blackstone is not concerned - the magic "freak out about your bearings" equation is when you have high wear of iron, copper and lead all together. Deren asked what kind of oil I used (LiquiMoly) and looked up what particular additives they use, as some brands will add more of this or that for various benefits.

He thinks LiquiMoly may be using a bit more lead additive than "industry average" to help cushion the bearings under high stress, and said to worry if chromium, copper, tin, silicon, or nickel readings started coming back high.

I will still follow up with another analysis, as the aftermarket warranty covers rod bearing failure, and expires at 145k miles. If I need to have this thing worked on, I want to get as much covered by Route 66 as I can!
