Oil volume
Total oil volume in the lubrication system of Rotax 912 S2 / ULS2 engine is approximately
3.8 litres (
1 US gallon
).
Check oil volume preferably after running the propeller by hand in the sense of engine rotation
so that oil can fill in the engine space or operate the engine for 1 minute in idle mode.
WARNING:
SWITCH OFF IGNITION BEFORE MANUALLY TURNING THE ENGINE!
The oil tank is located in the engine compartment and oil dipstick is accessible after opening the
lid on the upper engine cowling (see 10.2.1.2). Oil level must lie between min and max marks
(flattening) on the dipstick and must not drop below min mark.

Oil draining
Drain oil from the oil tank by unscrewing the plug (wrench size No.17) on the lower side of the
oil tank. It is possible to drain oil from the engine after unscrewing the plug in the lower part of
the engine at the hose of the return branch of oil flow. It is recommended to drain oil immediately
after engine test or after finishing the operation when oil is sufficiently hot and better flows both
from the engine and from the tank. Clean the tank before filing it with new oil – see the Rotax
Maintenance Manual.
Refilling oil
Refill oil in the oil tank that is located on the firewall.
Venting of the lubrication system
After short idling, stop engine and replenish oil to max. mark on dipstick. Never overfill otherwise
oil would escape through the vent tube during operation. At oil level inspect, do not exceed the
max. mark.
