Wow I had no idea so many of our engines had "normal" oil consumption in this sort of range (1qt per 1 - 1.5K it sounds like?). I change my oil pretty religiously at 3K miles or 3 months, and I'm still using 5W30 Motul 300V (which, while expensive and an excellent lubricator, as noted elsewhere isn't designed for long change intervals at all, and is low on detergents). Another reason I change more frequently is I have an oil cooler which I'm not draining on change, so every change leaves behind a considerable amount of used oil mixed in as well. I've never even seen a whole quart lost per 3K change, generally the loss is small enough that I hardly notice (under half a quart).

I'm going on 2500 miles and haven't burned a drop... That being said I broke the engine in per the owner's manual and typically drive like I'm retired. My first oil change I will be switching to Amsoil.

That's true, behavior can be a big factor. I broke mine in a little rougher than the owner's manual asked for (since I had read about the whole "seat the compression rings" thing). I run my engine pretty hard, although not as hard as someone who keeps a regular race schedule. But I'm also very adamant about letting my oil warm up before driving. I almost always let it idle up until the oil temp needle is at least moving (140+), and I usually won't go rough on the revs or rpms until 180. In the 2.5 years or so I've owned the car, maybe 5 times total I've been in enough of a rush to hurry that process in order to get somewhere I needed to be on time.
