Let it be known, that in the owner's manual, it indicates oil consumption of 1200 miles per U.S. quart consumed is considered "normal" Any lower miles for 1 U.S. quart consumed is considered "excessive consumption" according to the owner's manual.
Bear in mind if you are not happy with your current engine oil consumption, you SHOULD consider taking an engine oil consumption test by a Subaru service center. If your engine fails the engine oil consumption test, Subaru of America is obligated to, under warranty if vehicle is under 100,000 miles (unfortunately for you, this no longer applies), replace the short block for no charge.
