Amount of oil remaining in the engine

[1crosscut]

As part of pulling my engine to do some work on the AA I decided to see just how much oil is left in the engine after draining the oil.

I drained the oil allowing about 10 minutes of time until I put the plug back in.
Then I pulled the engine and mounted it on my engine stand.
After getting it on the stand I pulled the drain plug and caught the oil. Put the plug back in, tipped and rotated the engine several times over the next couple of days pulling the plug each time and catching the oil.
17 ounces is what was left in the engine.
