My thoughts:
The M1 0w40 seems to work well for my car, and could've gone much further than 6,000 miles. The iron is slightly elevated but everything else is fine so I agree that it's probably nothing. Considering how I drive the car to redline often coupled with the short-trip nature of my driving, and how high-strung the engine is to begin with, the numbers look good.
Fuel was probably elevated since I didn't drive it very far to get the oil change that morning and it was probably running a tad rich from the aggressive cold-start.
The only reason I changed it was because the CBS indicated I needed a change (it thought this was still the original TWS with 13,674 mi on it). I have opted to do "intermediate" changes at the halfway point between BMW's recommended 15k intervals. At this rate, I will probably change it again in the late winter.
