Talked to Roy and he said the break in comments on the bottle refer to older engines not those in modern production.

I put Redline in the Z3 at 32k miles (it was preowned) and it cleaned it up, as new....
Curious to see how your rod bearings would look.

Yes tight clearances means the load is spread more, which means the same bearing can handle a higher load, which may well be why BMW choose the clearances they did.

But tight clearances also needs thinner oil and smaller tolerances, and more rigid components (as it said in that video), but clearly something went wrong with at least one of these factors. And seeing as they choose one of the thickest grade oils for road cars combined with tight clearances, that's a major red flag.

I don't think the S65 has an exclusive on rod bearing wear with the high RPMs that it is capable of. Other engines also suffer from rod bearing wear if they're used at the extremes, not to mentioned with extended use oil at 10k OCIs = madness
Please show some examples of other high performance high RPM engines that show premature bearing wear.

Next UOA do TAN too. You want TAN with Easter oils.
SIlicone is not an issue in Redline. They pack Silicon in it. I have seen values up to 30ppm.
