I explained where I got my numbers from in my first post.
"Let me use some numbers I pulled out my head to explain."

I am trying to understand what you think you did by following your new procedure starting with the cylinders extended.

I fully understand what you did and are trying to do with your multiple flushes but can not understand why you think starting with the cylinders extended made any difference.

Yes if you start with the cylinders extended and then close them with gravity you will get more oil out of the hoses and cylinders. That's easy to understand.

But if you start with the cylinders closed this extra oil you got from the cylinders and hoses will still be drained because it will be in the sump to start with.

So in the end you are still gona drain the same amount of oil from the entire system no matter if you start with the cylinders open and close them with gravity or started with the cylinders closed.

Also moving the cylinders under engine power is gona flush the hoses the same as draining the system with gravity.

Maybe I am reading it wrong; so that is why I am asking; but it seems you are trying to say you were only able to drain 9 gallons of your 10 gallon system out the system because 1 gallon is stuck in the hoses in your first 2 flushes but are now able to get the full 10 gallons out.
I disagree. I bet you drained 7 gallons from the sump and then another 2 gallons by closing the cylinders with gravity. You still only got 9 of the 10 gallons out.

So I am trying to understand what you think you accomplished other than getting a little exercise closing the cylinders with brute force and gravity.
