Any idea what is the oil capacity between the upper and lower dot on the dip stick? Would that be about 1 quart?

A lot of manufacturers use 1qt/1k mi as the limit. It's one quart between the dots.
If I had to guess where it goes, I'd wager it burns some and blows the rest through the PCV system. I used to lose 1qt / 3k miles when I ran the factory spec oil. I run a slightly thicker oil now and it doesn't lose a drop. But I'm not about to turn this into a "what kind of oil should I run" thread.
