That's why I thought the 350,000 hrs, ZERO wear, was optimistic as well. Whatever lubricant they used, would change the world.
Another one that I think has become mythical is, if you have a problem, any problem with your diesel, tie a barge on the back and run it flat out for 3 days straight(Ok, I've exaggerated a bit).
Some would have you believe that will fix anything.
