Seems like the duratec is a pretty clean running engine. I'm at almost 100K miles and burning/loosing less than 1/2 Qt. between 3K mile changes. When you fill your oil, start the car, turn it off, check the level, and fill to max line. If you're using an extra capacity filter, it should say how much extra oil it holds and how much extra you need to add on fillups. My SE takes 5.8 Qts, but I think the SVT takes a bit more due to the oil cooler.
