How could changing the oil now (unless I went to synthetic) cause breaking problems?

When the engine is first built, the pieces are all trying to wear themselves down to fit together in a natural kind of way. Of course, oil prevents wear. Well, if you don't let the parts wear a little bit, you get pieces of metal that were designed to wear down that don't. So then what you have is an engine that is not supposed to be revved over 4,000 RPM for another 1,000 (or 3,000) miles. Isn't that obvious? If it's not broken in, you're asking for trouble.
And just because one person has not had problems yet, doesn't mean he won't. I would STRONGLY recommend you follow the manufacturers recommendations. Unless you think that every single car manufacturer out there is wrong, they don't test any cars, and have no clue what they are talking about. Sorry to be harsh, but man, they've been building cars for nearly 100 years now, maybe more, and you can't tell me that the manufacturers haven't figured out what a proper break-in does.
If it wasn't needed, they most likely would not make you do it. But they put stickers and warnings all over new cars.
And of course, if you have enough money that a $20,000+ car having problems is not a big deal, then ignore me. I personally could not afford to damage something that expensive.
