It is actually both. Yes, the main benefit for airplanes is avoiding
engine failure, but you can also extend drain intervals with oil
analysis. For large truck fleets, the analysis is typically all about
extending drain intervals.

I never used oil analysis when I owned my Skylane. I'm talking about

It depends on what it indicates is wearing. Some things you can let go

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.
