This is as important as loading the engine correctly.

Hey Vin, I have lots of respect for you and have learned much through your posts, but this procedure you describe seems pretty extreme to me. I've had many new vehicles and have never broken the engines in this way. For my X5, I just followed what the manual says and didn't do the redline or the up-hill in high-gear thing. My MPG seems to be on par with everyone else's and she doesn't burn a drop of oil after 34k. I'd say the rings are probably seated just fine and I fail to believe it's a stroke of luck. If all this really made a difference, I'd say 99% of all BMW owners would be having serious problems with their cars as I'm guessing it's less than 1% of owners who actually do this.
