"Awhile" shouldn't more than about 5 minutes. The correct fill level relies upon some oil remaining in the top of the engine; its to be checked during refueling stops, etc., not after sitting overnight.
Regarding FSS oil change intervals on older models (feels strange to say that BTW), the max allowed is one year or 16k miles. Mine trips at 16k usually as I drive 110 easy freeway miles per day. If your mileage includes lots of short city tirps where the engine doesnt get to full operating temp FSS will reduce the interval accordingly. At 16k miles, my M1 shows virtually no soot or fuel contamination and retains more than 50% of its TBN's. I'm very compfy with the interval based on my driving style.
