Recommended Preservation Oil for Rotax 912

Hi Bill,

I only have the experience of one stored Rotax 912.

On the advise of my local Rotax agent/dealership

Not connected to Oil Tank, Oil Cooler, Coolant Radiator, Fuel.

All fuel drained

Engine kept in dust proof "shipping" box

All openings, including oil reticulation lines/hoses plugged.

Engine filled with almost  4 L of fresh  Aeroshell Sport plus 4. 

At monthly rotation;

Engine "tilted" & paused, through all axis, to coat internal components with oil.

One plug/cylinder removed and a small quantity of Aeroshell squirted into cylinder. Plugs holes covered with rag, to soak up any expelled oil. Engine rotated about 3-4 full rotations.

Plugs refitted (finger tight).
