I had my S65 seized on 50k km because of main bearings, running on Red Line 10w60 from factory. You can find my old topic with photos here:

So after engine rebuild (new engine block, pistons, BE bearings, ARP bolts) I'm running Mobil 1 0w40 to keep my main bearings safe, just like my friends (RomanK and toolshed) above with no issues for about another 50k km.
