Hi, I just found out my mother has driven 8k miles with her 98 Corolla
CE since she last changed her oil. I insisted she go with Mobil 1
synthetic last time she had it done, so I know it can safely go 5k (or
more?). Other than making sure she changes it ASAP, and keeping her
with a good synthetic, does anyone have any advice as to what we can
do to diagnose any damage she might have done? The car has only 53k
miles, and is mostly city-driven, though rather gingerly.

Thanks!

Personally, I wouldn't worry about it - doubt if she's done any damage.
IIRC, for the 2 Corollas (one of which was a '98) I had before my present
one, the manual suggested oil/filter changes every 7 - 7,500 miles anyway.
That, plus where she's been driving - not on dirt roads, for ex. - I'd be
surprised if it's created a problem.

Just guessing: if the car has been driven gently, then I doubt it
has been damaging the oil too badly, so 8 kilomiles may equate to
a much shorter distance with your average driver. And: the car's
mileage was 45K, by when surely most rough spots should have been
smoothed off, reducing metal dust production, AFAIK another cause
of oil contamination. (Whistling past the graveyard? Hope not.)

You (she) should be okay.

While it is bad practice to go that long, therre are lots of cars that have
a specification that is this long, or longer. I suggest yoju find the actual
specification for this car and follow it. I would not be surprised to learn
the spec for an oil change is 7500 miles.

I followed the maintance schedule for my 1988 Supra and have had
no problems (don't burn oil) in what 19 years now...

Oil & filter every 10,000 miles

If it makes you feel any better, BMW recommends 15K oil changes when
using mobil -1
I think it's too long, but 8K is definitely not a bad thing. Also
depends on the driving. If it gets fully warmed up frequently there is
nothing to worry about. I'd even stick to 8K changes then.

8k isnt bad at all. honda was recommending 7500 mile changes for the
civic, using regular oil. id only be kinda worried if she went 15k
without a change...

I wouldn't worry because back in the 1980s, when oil was a lot worse
than it is now, Toyota's recommendation was every 10,000 miles.

According to the 1996 Consumer Reports test of motor oils in NYC
taxicabs, 6,000 miles was fine, and even that oil is considered worse
than the current stuff.

I know of someone who never changed oil the whole time he owned the
vehicle.

Years ago a friend had a friend who worked at a local garage and he
told me this story (i.e. this is a third hand story, so beware).
Supposedly a girl came into the shop with a Mazda GLC (4 cylinder push
rod engine) that was making some ominous tapping noises. Step one was
to remove the valve cover. When they pulled it off, there was
literally so much gunk built up in the engine's overhead that the gunk
was molded into the shape of the inside contours of the valve cover.
You couldn't even see the rocker arms for the gunk. The car had
somewhere around 75,000 miles. The mechanic asked the girl if she had
ever changed the oil. She responded along the lines of - "Do I need to
do that? I added oil sometimes."

Well, she too, but this was someone else. They towed the car in for a
new engine job after which I think he got rid of it. It was a Toyota,
but having not changed oil in 50 or 60 k miles I guess the car just gave
up. Hey, it's only money.

I still change my oil at around 3000. Short trips and sub freezing
temps dictate more frequent oil changes.

I've stretched my usual 3000 to 4000 now. My manual on the '92
suggests 3750 for 'hard' driving.

My treks north can all be made in one oil change.

You're worried about damage at only 8K miles? As long as the oil level
wasn't low, an 8K oil change is not going to cause any damage. The
non-severe service interval is 7500 miles for the 1998 Corolla. As long
as some of the trips are long enough for the engine to reach operating
temperature, so the water in the oil will vaporize, don't worry. If you
want to be very cautious, stick to a 5000 mile interval with regular
oil, or 7500 mile interval with synthetic.
