This rate of oil consumption is completely within normal limits–even for a new car.
As a result, I suggest that you not lose any sleep over the issue.

And, yes, you should maintain the oil level as close to “full” between changes as possible.
I am an advocate of adding oil once the dipstick shows that the level in the crankcase has fallen by 1/2 qt. Just be sure to add slowly, so as to not overfill the crankcase.

I concur.
