oil guzzling..

My car's been an oil guzzler in the past month or so, it might have always been an guzzler, but since i drive it for short distances daily (10-20 miles) daily, i haven't noticed. Recently though, i made a trip up to San Jose and back to Pomona within a weekend, and my car guzzled the oil from a bit over full, to a bit below min on the dip stick.

The car has very minimal oil leak, a drop gathered at the bottom of the engine block every 4 or 5 days. I've checked the compression as per Mike Z.'s suggestion, and i'm getting a consistant 130lbs of pressure. If my understanding is correct, that's well within the green zone.

Any suggestions on what i might check on next?..

There are only two ways to be losing oil that I can figure on - leaking it or burning it. If you are not leaking it then you must be burning it. Have you noticed any exhaust smoke? Have someone drive behind you for a few miles and see if they can detect any smoke while shifting, deccell., accell., etc.
Compression of 130 is OK but is getting to the low end of the range. Other than bad rings, the only other places for oil to get into the cumbustion chamber is valve guides or intake (breather system).
Valve guide wear is measured by removing the rocker assemble and rocking the value stem back and forth. If you have a dial indicator you can measure how far it moves. I do not know what the spec is but those are the places to check.

You might want to check the PCV valve and while you are at it, disassemble and clean the filler neck/breather box assembly to make sure the engine can breath well.
