Default Oil Leakage in High(ish) Mileage Camry

I've got a '99, 4 cylinder Camry with 92,000 miles on it and I'm
loosing about a quart of oil every 2,500 miles.

I'm wondering how this compares to a typical car. One concern is that
I ran the car with low oil for a while (guy who changed the oil didn't
screw the plug on tight enough), and am wondering if this might have
caused some permanent problem (?)

thanks in advance, Jon

Running low on oil is not the same thing as running the engine with
the oil pressure light ON. As long as oil pressure was never
compromised, it's unlikely damage occured. If oil aeriation occued
due to low oil pressure (but not low enough to kick ON the oil
light), then I would be most concerned about connecting rod bearing
damage. Since the "low oil level" experience, have any unusual
engine knocks or taps come to your attention? Also, valve guide
seals (being rubber of sorts) will harden with age resulting in
greater oil consumption. This happens to all engines eventually.

That's still within reasonable limits IMHO. Opinions probably vary, but once
a car starts burning more than a pint per 500 miles, its time for an
assessment.

Not as long as the engine still had enough oil to maintain oil-pressure.

If you are leaking it could be from the
rear main seal or if on the timing belt
side of the engine it could be cam
shaft seals, or oil pump seals.
If your burning it I suspect it may be
from your valve seals, doubtful from
the piston rings. Try some high mileage
type oil that will swell the rubber seals
a bit to slow the flow...

But not if you change the oil and other fluids at regular intervals
though,.........right?

Taking your response seriously .... all seals will harden with age
irrespective of the oil used. I can personally attest to that in my
last car. But instead of a rear main seal leak at 100k miles, the
oil rear main seal leak started about 250k miles.

Thanks for the responses. No unusual knocks since the low oil
experience...

I'm facing the sell versus keep till it dies decision. In another
thread regarding synthetic oils, someone mentioned it doesn't make
sense to switch in a high mileage car, if you are already leaking oil.
If I keep the car, it seemed to make sense to switch to synthetic
oil--can anyone explain the counter argument for when you're already
leaking oil?

thanks again, Jon

It's fair to say that installing synthetic oil in an older engine
will NOT seal up weeping/leaking seals. Get the seal replaced.

I can attest to that also. The rear c/'shaft seal was allready leaking at
155,000ks or near enuff to 100,000 miles in my '96,....thanx to too few
oil-changes by the previous owner/s.
