I'm not sure this is accurate, but I had a '99 VW Passat and I'm pretty sure it was on that forum where I read that VW (and perhaps some other manufacturers) use a special break-in oil from the factory. They actually want you to leave it in for the full change cycle. I remember the VW used 5K mile oil change intervals, and everyone was talking about the "US paranoia" of 3K intervals. VW specifically did not recommend changing the oil sooner. Don't know if BMW, MB, etc also use special factory version oils. At this point I'm planning my initial oil change at 7500 miles (currently only have 700 )

At that point, I think the motor has proven itself as being defect free and from then on I use the brand of my choice, so long as the viscosity is in the range of what the manufacturer recommends.
