Richard,
Your post got my curiosity up. Last oil change 40 quarts 6k ago.... I went and checked my oil level. Still just above the full mark with no toad rust proofing. This I do know from the aircraft engine world....each engine would find its own level and stay there with many hours of operation. But fill it up and in short order you will have blown out the oil down to its own level.
