Where does my oil go??

I have been into cars for 15 years, Mustangs for two and I know quite a few things but this one has stumped me. I have to add about a quart of oil every two to three weeks but I have zero drips and no smoking what-so-ever. So, where is all that oil going? If it were the piston rings, I would think that it would smoke and foul the plugs but the plugs are all clean and even a little white. Valve seals, same thing, smoke and fouling. I know there is no dripping. The motor and the underside is completely clean too. I like my car immaculate and I would notice a quart of oil on my motor. It's just not there. Drive way is drip free.

So, WTF. I do like to run it up to 5000-5200 frequently on the road. Could it just be breaking down? The oil has to go somewhere. Does anyone else have a similar problem?

So you think it may be rings? The car only has 80K on the motor.
