...And it looks like oil analysis did not lie.

These bearings were WPC treated. I haven't seen any cars with WPC treated bearings with even half this mileage, so I think it's possible (but in no way guaranteed) that this shorter life is a result of the WPC treatment.

I put in new, OE, untreated bearings with OE bolts.

Thanks again, Nick/Danny, for coming down!

Damn. My car received WPCs from Kaiv not long ago... I hope it goes way longer than that...🙀 I'll keep you posted after I test oil next up ... good info. Good post.
