I also have an M30 with the same hose set up and the same engine angle. If I use that hose I can only remove 3 quarts of oil. The drain hose is on the high side of the oil pan! If I use the oil fill and a fluid vacuum I can get 4 quarts out. Either way it never gets completely drained. I change the oil every fall and seldom use a full tank of fuel in a season. If nothing else I would like to be able to monitor the base level of my oil before it becomes acidic so I don’t recycle the oil years too soon. It just seems like a waste but changing often is better than not changing oil at all.
