This s a longstanding mystery, Bald. It's hard to believe that a volume manufacturer, like Toyota or GM, is bench testing and bench-breaking-in each and every one of the hundreds of thousands of engines that it produces each year. Maybe M-B or Porsche do it on some of their models. On the other hand, I suppose they could fire each engine up for a few seconds, once it reaches the end of the production line, just to look for major leaks, etc.

I do not know. This is akin to that other great mystery, i.e., Is there such a thing as break-in oil from the factory?
