At about 105,000 miles, I changed the Optispark & decided to go on in and replace the timing chain & sprocket. When I got it apart,it was worn at least as bad as if I'd used conventional. This was an actual visual inspection, not some theorizing or general gum beating. Also, reading other message boards, this seemed to be a common experience with this engine using Mobil 1. Now, I'm not saying it's no good, but the evidence is there, except for those unwilling to see the emperor has no clothes. The proof is in the pudding and Mobil 1 pudding has a lot of iron in it.
So what you are saying is , your engine has a design flaw that no oil can can stop?
