I'll be changing my oil in the next couple of weeks (5k miles from last test). Hopefully the switch to 0w-40 and shorter intervals will help me even out my lead wear.

I think it's possible that bmw used up whatever leftover inventory of leaded bearings they had and that this inventory lasted partway into 2011 production. I think that's why some 2011 cars have the leaded bearings and some have the unleaded ones.
