I have occasionally seen weird behavior like this on my GS-R. It
isn't losing coolant, just takes a long time to get an accurate read
on the dip stick.

Verify you aren't losing coolant. If not, just make a point of
checking the oil only after the car has been sitting for a long time.
I assume the car is always on level ground when you check it.
