Good choice on the M1 0W-40!
CAUTION: Only put in the amount that you extracted, if the level on the dipstick or meter was good!!! Then make sure your oil level is not above the high mark, if you have a dipstick or level meter.
Your engine is different than mine but when I extracted everything I could out of my MB M133 engine (2.0L turbo) there was still a quart or so more of oil still in the pan. I couldn't get all the oil fully extracted with a pump in the dipstick tube. If I added the normal amount of oil for an oil change, I would have been quite a bit more than what is required. From my understanding, for this engine (M133), any overfill of the sump will cause problems with the PCV system; a costly fix. I am not sure but I hope yours's is not as sensitive to an overfill.
Anyhow, sampling the oil at the interval you mentioned would be interesting, looking forward to the results. The M1 0W-40 is worlds better than what was previously poured in and should exceed the specification you are looking for.
