Industry standards (from what I'm told) don't declare it excess oil usage until it exceeds 1qt/1000-miles. Personally, I'd be annoyed, but that's what the industry says about it (and likely the same thing BMW uses as it might trigger the Lemon Law). Luckily, mine (a 535) has a bit over 10K on it, and the computer says it's still full. The V-8's generally are much thirstier of oil than the I-6.
