Probably 7.5k to 10k and you're good. I wouldn't go over 10k though just to be safe. I think this is also fiscally responsible.

From what I have heard from BMW techs, the service indicator was put into place to mainly save BMW money on vehicles with free maintenance. It's enough to get by and keep the engine going long enough even after power train warranty expires. Now I don't think there are any longevity tests of an engine being run with high quality oil for 15K intervals vs 7.5K intervals but private oil sample tests show differences in how well the oil protects. :)
