There is NO such thing as an engine that does not wear at least a little bit. When I talk fuzz I mean it wipes out flat to turn into seeming oil (the gray residue), it is that fine, and off cars with well over 200K miles on them, they have done it all those years. My bikes were the same way yet never tore up one early ever.
Mobil 1 is nothing special, I saw the same on cars using it. I run conventional oil at 9K OCIs too. No sense in wasting money on synthetic, can't kill the cars now.
Making money with every oil change.
