All good points made above. Another point not made as yet is the level of oil relative to the rotating mass, which should determine a correct quantity, rather than any other factor which may be variable due to a mismatch of dipsticks and/or oil pans and oil pump pickups, as well as the depth of any accumulated sludge present at the bottom of the pan. For the poster of the question, I’d say your issue is serious enough to warrant removal of your pan for inspection.
