Question about 1995 Honda Odyssey
1 qt every 700 miles
How many miles?
can be bad rings.
or bad valve seals.
do a compression test then a leak down test, and bingo the answer.
if both pass, the valve seals are bad.
if not rings are bad, if the oil test for compression fails the valves them selves are bad, if the teaspoon of oil test , passes the rings are shot.
read up on all compression tests. using google, or by any car engine book, one that tells you how to test for this.
The leak down test, can even tell you which direction the leak happens
using a rubber hose to your ear.
i can hear air leak to crankcase, valve cover oil filler, oil dip stick hole, and to intake plenum and even hear it at exhaust ports. sure can.
one the oil control rings on old engines can stick down and be
near useless. stuck in the lands. seen many like that.
Id use the 2 gauge to judge engine condition,
if bad, its hopeless. (bottom end bad)
if good, all tests. then the valve seals are bad.
there is a way to change them head on car.
using shop air , or other wild tricks.

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.

Don't add transmission fluid to your engine. You can try doing a motor oil flush. But most likely you need a valve lash. Every 80,000 you should have an adjust of the valves/lifters.
