US Car break-in poll...

By the way, you were right. I went back to my car and I found the same wording in page 15 of my Spanish manual. In the way is written, it seems to be mandatory and not recommended since in not part the text they use that word.

I took delivery in Leipzig. The guy delivering it said no break-in other than limit revs until oil fully warmed up. I tried to keep it under 4000 RPM for the first 100 - 200 miles but hit 150 MPH after that, and then 188 MPH after 500 miles.

Well, while on the topic of logical fallacies, clearly the whole idea of a poll is an "appeal to the masses" which is equally flawed. I still find value in this poll though, even if it evokes some upsetting cognitive dissonance. Based on the prior threads, I would have never guessed that a clear majority is following the book. There's probably a self-selection bias among the people who explain/justify their position, however, and among people who quietly tick a box on a poll without explanation, so I accept that this poll is only accurate to +/- eleventeen percent.
1. Factory manual gives contradictory advice to different markets. Boom. Credibility? None.
2. Factory DOES build in protection whenever there IS actual risk of damage- redline limiter, for example. Factory does NOT display ANY indication of "break-in rev limit exceeded." Credibility? Blown.
3. Factory DOES build in protection that limits the engine during shipping. Factory does NOT do ANYTHING to restrict owner use during break-in.
I won't even mention all the times people have gone to the factory and asked about this and been told there's no reason not to drive the car as hard as you want as soon as its warmed up. Oops, too late, mentioned it.
Oh well. Given all the inconsistencies the majority are happy to believe I'm sure I'll be forgiven that one small lapse.

I don't understand why anyone willing to give this any thought at all would follow the book. I mean, think about it. Seriously:

I picked up my GTS in Stuttgart on Oct 2015. I too was recommended just to let the engine warm up first and then drive normally. I followed this advice. My engine died at 2,367 miles while driving back to the factory to return the vehicle for shipment to the US. Obviously, likely a defective engine, which was replaced with no questions asked. Had I followed the brake-in recommendation, the engine would have probably died in the US and had to be replaced by a US dealership (not ideal).

Its not that I'm totally without sympathy. When you have so much invested in a position it has to be painful to see its validity so utterly destroyed so clearly and conclusively. But the facts are the facts. Even taking your point of view for a minute, how does it help your position at all to so completely ignore the facts while instead being personally insulting? Are we trying to learn? Or bully?

In addition to following the factory guidance - I've spoken with 3 different head techs. Their guidance is always the same. If you plan on keeping it , follow the manual, if you're going to get rid of it, drive it the way you want.
You're talking about micro-finished machining - the parts need to wear in. If theoretically no wear is occurring then the metal parts of an engine would last forever and never need refinishing.
Chuck I'm surprised you haven't quoted your lawn mower break-in article again?
And candidly, why are you on this forum- after 1,000 bloviating posts you "test" drove a 991 and said it wasn't for you. So you don't own a 991, and don't like it enough to get one - why post here?
