2001 Corolla Incredible Oil Consumption, Good Compression

Three months ago I purchased a 2001 Corolla with 80k on it. I have now discovered that it burns oil to the tune of 1 quart per 200 miles (yes, 200!). Please consider the following facts: The 1.8 liter engine runs and sounds great. It has no oil splatter anywhere underneath or under the hood. The parking spot is completely free of any drippings. There is absolutely no blue exhaust even on initial startup. Compression tests on the cylinders revealed 200 psi per cylinder with proper needle reaction (book says 145 min. 218 max.). The spark plugs did have white ash on them but were dry and not eroded.
This is mind blowing, where is all that oil going? Thanks for your service, a donation has been sent.

Thinking that at higher rpms going down the road is where its burning it( high vacuum condition). The comp test has you at the higher end of spec. Also an indicator of oil in the cylinders. If the problem is the same on all 4 cylinders, ie runs smooth, then I would do some research into recalls and campaigns that there might be on that engine/car.

If visual inspection fail to locate the cause high oil consuption.
Clean the outside of the engine with a steam cleaner or solvent.
Drain the oil pan and refill it with recomended amount of dye and use a black light to look for fluorescent yellow or orange color.
Or use this one:
low or high pressure testing.
