Thank you leadfoot! I have the original KL sump + 380 motor, but expect it should be the same.

I believe I'm getting all the oil out of the sump because I usually pull out about 4.5L. The filter probably retains most of its .3L of used oil.
Now 0.3L out of 4.7 is about 6.5% left in there. I'm not worried about that amount of dilution given that I change the oil fairly frequently.
