Losing oil, no visible leaks. 120,000 miles
Hm. In my experience if you lose oil at the rate of 1 qt. per 800 mi. it's going somewhere. Actually, if you lose 1 qt. per 1000 mi. and change your oil every 3,000 mi. it's under $10 in oil you have to buy to keep it topped off, and some places say that's there's nothing wrong.
But, your case is a little more serious.
I think that it's probably leaking past the rings and/or valves and the catalytic converter is eating up the oil, so you see no blue smoke, like you would in a car that has no converter (I'm assuming you have a catalytic converter on your car as my 1981 Honda had).
After 100,000 mi. little irregularities in the piston cylinders can develop, and seals can gradually degrade. So, this is normal for that kind of mileage, although there are people who get over 400,000 mi. on their cars with just regular maintenance and driving highway mi.
You might want to try one of those slower burn oils designed for cars with 75,000 mi. and above. That might slow the burn off of oil down to acceptable levels.
Good luck with it.
