It depends on where you keep the oil level on the dipstick. With most 150-152, anything above the 5-qt mark will get blown away quickly, giving you an inaccurate idea about oil consumption.

I use the empty oil bottles to make a bunch of bottles with 1/2 qt each, and add a bit of Camguard. When the oil level on the dipstick gets down to 4.5 qts, I put in a 1/2 qt bottle. On average, my plane uses a 1/2 qt every 6 Hobbs hours.
