Right.

So for a second owner, where the manufacturer has no interest, a
decrease in oil change intervals is cheap insurance--no matter what the
owner's manual says.

OK, post a reference to some real data.

Could be many short trips and never getting the engine to normal
operating temperature. The condensation from combustion will accumulate
in the oil over time without the opportunity to evaporate off causing
sludge. Had tis happen to a Chrysler 3.3 engine once (caused the
lifters to become oil starved). Switched to Synthetic and not a problem
since.

BTW: What specific engine problem would cause this to occur (except
perhaps a stuck-open thermostat)?

Constant short 3-4 mile trips could do it.

Leaking head gasket allowing coolant into the crankcase. Cracked block
or head allowing same. Many short trips in cold weather.

I don't recall there being a date at this site, but the car was
purportedly a 2001. So, if this occurred just recently, then this car
may have been five years old when the engine was torn down. 8700 miles
over five years, is very little driving. And if this was the original
oil and filter as was suggested, and if this car was driven in a cold
climate, then that would constitute extreme abuse and might well
generage that much sludge.
