Anyways...Answer to my question?
The answer to your question is that the oil level indicator is very slow responding to changes in level. It needs a day or two of driving to assess what the actual level is. You can do a "quick read" but that won't be particularly accurate.
The way to think about the M3 oil level is that the bottom of the indicator is the "OK" line, and anything above that is "Extra". You don't need any "Extra" to be OK. The dashboard light indicator will tell you if the level is not OK, and until then, don't spend any time thinking about how much "Extra" you should be carrying around.
