It is ..... at least worn cylinders/rings.

Because it's cost prohibitive to re-certify the engine and the
engine/plane combination. thank the FAA for that one!

Well, I have to agree that auto engines are definitely more state of the
art, but comparing the life of your car engine to your Lycosaur isn't
really fair. You don't treat them any where near the same, as was
alluded to in some posts. Your car doesn't sit idle for weeks (or
months) at a time and then get run a little bit. Most airplanes in
private ownership (non-flight school or other business related
operation) get treated that way. The accelerated cylinder wear that
causes high oil consumption is due to the rust that forms in the
cylinders when the plane sits for an extended period of time. If the
plane is flown regularly and about 100 to 150 hours a year, the lycosaur
will go to TBO without even getting a top!!! The secret is regular use
and care.
