Not saying you have to cruise at that low of an rpm but 3k-4K is high to just be cruising at.
Also, as the other guy said are you sure it was full when you bought it? I wouldn’t be surprised if CarMax changed the oil before selling it and only added somewhere between 6-8 quarts.

I would say then 2-4 K. My intention was to say the range I drive at most of the time..
It was full (in fact, it was a little less and I made them fill and checked) also my calculations are after I changed the oil using a local shop with 10 quarts and AC Delco filter. I confirmed the level after their oil change as well.
