It doesn’t smoke, and there are no leaks, so it must be burning oil.

I’ve owned two Corollas, and I’ve added a half-quart into each per every second fillup (I fill the tank at a spot between 1/4 full and 1/2 full). A quart per thousand miles is pretty good with an engine with 167k on it, especially a hot running engine such as yours.
