Ideal amount of oil for a /6

Mobil suggests that Mobil1 can be used for break-in:

Yes, Mobil 1 is factory fill on many new cars. Read the fine print, it says "The fact is, current engine manufacturing technology does not require this break-in period." Even though I rebuilt the 318 in the Demon recently, I don't consider it to reflect current engine manufacturing technology.

My engine builder friends say that the rings will seat quicker with conventional oils. If I wanted to go to synthetic, I should wait for the first regularly scheduled oil change. I'm following their advice.
