Read the OP, then read my post. I'm pointing out the absurdity of worrying about every last drop of used oil in the motor.
This is just an anecdote, but you know how automakers changed up the recommended oil change intervals in the late 90's / early 00's? It took a TON of durability testing to do that. Supposedly during that testing, GM engineers figured out that at highway speeds, the typical LS1/LS6 ate enough oil through blowby that they could top it up with mobil1 and swap out filters every now and again, and basically run it indefinitely without actually changing the oil because they were putting in a fresh quart every few thousand miles.
With that in mind, a tablespoon or so of used oil trapped against the body of the fumoto valve probably isn't going to blow your car up.
