My car has over 120K on it and it started "leaking" around 80K, I
started adding oil for over past 2 years and I had another Corolla
which did the same thing and fortunately its engine was rebuilt within
the warranty period(about 30K miles). I know the cost of rebuilding
engine is so high that I may have to live with it by adding oil every
week, but it looks like too much to me nowadays.

If you're _really_ adding a quart for every 300 miles, there should be oil
all over the place. That's a quart for every tank of gas. You can't consume
that much oil and not see where it's going.

It's either coming OUT of the engine, in which case it should be all over
the garage floor; or it's going THROUGH the engine, in which case it should
be all over the back of the car. Or it's doing both, in which case there
should be a mess on the floor and on the back of the car.

Look around where the oil pan meets the engine. If it's got oil all over
it, the oil pan is loose. *GENTLY* tighten the bolts. They snap easily.

It seems hard to believe but I have not seen any oil on the ground
where I park my car nor have I seen the messy on the trunk lid of my
car. I once tighten the bolts around the oil pan, but it didn't help
much. I feel so puzzled where the oil went for those 2 years, maybe it
is the time for me to take the car to the dealer. But I hate it when
the dealer says something fixed, then I have to come back again to fix
something else, until they tell you that your car engine need rebuild,
that was how it happened to my other Corolla.

Why pay money to a company whose service doesn't make you happy? How about
asking everyone you know if they know an independent mechanic they've been
happy with for a number of years?

There are two possibilities, the oil is leaking or it's burning. If it's
leaking, the undercarriage will be wet with oil, if it's burning, the inside
of the tailpipe will be black with soot, and the rear-facing panels on the
car shoule also be black from oil and dirt.

I suppose oil could leak into the combustion chambers (around the valve
seals) slow enough that it could burn cleanly enough that there was no trace
on the rear-facing panels, but if that was the case you should not be using
a quart every three hundred miles. Another route for the oil to take is past
the rings, but the rate that you have to replace the oil indicates there
ought to be visible signs of where it's going.
