There are plenty of Aeroshell oils
I obviously ment the type used on Lycoming. (Not the “Sport” type)
Gearboxes have (or at least had) a 600h limit. Haven’t investigated what they are on these new boxes.
As I said. The iS is no worse than the UL/ULS variants in terms of number of errors/failures IME. But the failures on the iS are much more difficult to pinpoint and repair. All in all it’s more grief than standard versions.

Those were the UL gearboxes (not ULS) without the slipper clutch; mine would be 1000 hrs inspection with slipper clutch cleaning of lead should I have run it on Avgas more than 30% of the time…
