This is pretty much the case. There have been guys on the E90 side who sent their oil at a different intervals. and it starts to break down around 8,000 miles but is still good for most. At 10,000 miles or so, the oil starts to get a little nasty with a lot of wear metals per Blackstone reports but the senor still say's 15,000 miles for an oil change.
