^^^ okay... while I'm not disputing your Blackstone findings or your personal choice (although, what were your lead wear values?), my gut tells me that empirical data should be interepreted conservatively but not disregarded entirely.

I didn't find it to be confusing. What I find confusing (and possibly misleading) are the various specs reported from oil companies that may or may not translate into improved wear protection for a given engine -- on the other hand, these data for the VQ35 are exactly that.

At worst, these data are imperfect (no data are 100% free of error), but I don't think they ought to be dismissed out of hand either.

I don't know that we'd see wildly different wear characteristics on the same motor for the same sports car driven by different drivers (all of whom are probably car enthusiasts, and not especially gentle on their car), although some variation certainly might crop up, it shouldn't be enough to make the data worthless.

As to Redline being Ester based, that is a good point -- however, I have yet to discover a reason Nissan recommends their Ester oil other than it allegedly being good at reducing valvetrain chatter. Whether or not it does, and whether or not it matters for engine longevity, is unclear to me.
