I've gotten the free 1 year/10k oil changes but I've always done a change myself between the free change. Per my UOA tests, the BMW 0W-30 is getting close to falling out of its viscosity spec at ~5000 miles. Everything else was well within spec. I wouldn't push the oil past a 6000-7000 mile change. That's my plan after my last free change.

This is great info, I just put 0W-30 in mine for the first time. Wanted the cold temperature protection for winter but was worried about the longevity. Did you ever test 5W-30?
