1 in 4 or 5 is WAYYYY too high. Having this in the back of your mind takes allot of the fun out of it. Particularly when you are tracking and autocrossing it. I would be inclined to believe that putting more exertion on the engine will bring a hidden flaw to the surface, whearas casual cruising will delay the onset of an RMS tear.

But Hat's off to BMW and Lexus for simply fixing their problems as soon as its flawed engine designs came to light. But when Porsche is making mo money mo money mo money (albeit less than before) they obviously came more about maximizing profits vs. protecting their reputation.
