More than likely it's the valve guides/seals. Cats do a good job of cleaning up the smoke.

I meant per quart.

Oil usage per amount of time is irrelevant.

125K per quart would be pretty good!

One quart per thousand miles is not unusual.

Just keep a spare quart in the trunk and add it every 3rd fuel fillup or so. That's what I've been doing for th last 20K miles since I got this car.

FWIW, a thicker viscosity oil will be consumed more slowly, by at the risk of inadequate lubrication in the tight tolerences.
