I never used oil analysis when I owned my Skylane. I'm talking about
what others do. :-)

It depends on what it indicates is wearing. Some things you can let go
for a while, and some you can't.

Yes, depending on the above.

If the oil was bloody, I'd really be worried. :-)

With a car, sure I'd just keep on driving it. Oil analysis can't
predict with any certainty when an engine will fail. In a airplane, I'd
have it torn down and inspected. However, this is much easier than with
most cars. A good aircraft mechanic can rebuild the top end of an
airplane engine in the time the car mechanic is getting the accessories
removed from a modern car.

To rebuild a small airplane engine costs about $20,000 and takes months.
You don't want to do it unless you have good evidence that it is needed.

I was talking a top-end. That can be done in two days tops. And a full
overhaul doesn't take months. Where'd you get that? A good mechanic do
do that in 3 days. And many folks get a factory reman and that takes
about two days to do the engine swap.
