I've read similar things about that too, but it's mostly related to engine that have tightly fitted piston rings. Most GM engines have very tight piston rings, which is why most need a top end rebuild after about 100,000~ miles (especially on the corvette). The thing that scares people about this little oil usage is that the VCM engines can shut the cylinders off from allowing an ignition, varying from running on 3, 4, or 6 cylinders. There very well could be something that causes the cylinders that aren't firing, to use more oil, but in that case, someone who cruises, or drives slow, would be getting more oil usage than someone who floors it all the time. Have you ever noticed this cwa107? I wasn't the main driver of the odyssey, so I don't know about it.Only when the engine starts to get "old" do you start to see oil consumption...and I wouldn't expect to see a worn engine to "eat" 1 quart every 3,000-4,000 miles until is over 100,000 or more miles (depending how the engine was driven & maintained).

Yes, indeed. On Piloteers.org (formerly Honda-Pilot.org), it seems that those with the highest consumption are the ones who are driving primarily "highway" mileage. Also, I didn't notice it initially when I first bought the car, but then I was doing a lot more varying of engine speeds and throttle input during break-in. Now that I've found the sweet spots to achieve the best mileage, I'm a lot lighter on the pedals in general - and sure enough, I'm noticing significant oil consumption.
