I'd hate to open a baby fresh motor but if it serves a valid purpose I'm not opposed to it.

I'm also excited about sending the oil from the 1,200mi service to Blackstone. Would be extremely interesting to see what the results are on a brand new motor. I don't recall seeing any break-in oil reports from the S65.
IMO not worth either of those things. A break in oil analysis will prob just show elevated levels of metal as things break in
