Hi Hugh,
Nothing really wrong with the old Aero Shell, they justed wanted to tune it up
and make it better for its specific 912 application. They went through a lot of
time and money to try and find areas they could improve on.

I wonder if this means we can now burn 100LL AvGas in our 912 engines

100LL, lead is lead no matter what oil. If you are using 100LL then you need semi
synthetic and not full synthetic. If you are using 91 oct. then either oil
is okay.
For the 1500 hr. Engines or a 2000 hr. Engine using lead more than 30% of the time
the gearbox gets inspected and cleaned at 600 hrs. If you fail to do this
the overload clutch at about 800 hours will be leaded enough to be non functional.
The 2000 hr. Engines using91 oct. has a 1000 hr. Gearbox inspection.
