When I did an upper end rebuild I dropped the oil pan on my 3 QM 30.   I always 
assumed there was oil left in the pan after pumping it out via dipstick.  Maybe 
a tablespoon left.  I was impressed.

Subject: Stus-List Engine oil drain hose

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.
