Same here, I do about 5-6K in 6 months, and change the oil in June/December. Those months carried over from when I lived in NY, just before the heat, or real cold weather. It would be slightly lower on the stick but not enough to add any oil.
Still a qt in 6,000 miles is nothing. I'd think a little oil making it to the top of the cylinders is a good thing, especially if the car sits for days at a time before getting used again.
