I always shake mine. Recently even after shaking I found dark additives sitting on the bottom, so I poured some oil from another quart bottle, shook it up and poured it in. Gotta make sure the oil spec is correct.
I think this is like buying gas at a high volume place vs a low volume place. You are likely to get fresher fuel and less water.
Buying oil from a high volume retailer would probably mean less possible settling of additives.

Well..... I think the high dollar oil sits on the shelf longer.
The cheaper stuff has higher turnover rates.
I have oil "stashes" (most of which was less than $2 quart) so i always shake it up because it sits in my shop for many months.
