Exchange / Refilling oil
Refer to the Rotax engine Maintenance manual Chapter 12

NOTE
Refer to Rotax SI-912 i-001 latest edition for recommended kinds of oil.
Type of oil used by aircraft manufacturer is shown in 17.5.
10.5.1.1
Oil volume
Total oil volume in the lubrication system of Rotax 912 ULS engine is approximately 3.8 liters
(1 US gal, 0.84 UK gal).
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 10.2.1.6). Oil level must lie between min and max
marks (flattening) on the dipstick and must not drop below "MIN" line.
10.5.1.2
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 Maintenance Manual for ROTAX Engine.
10.5.1.3
Refilling oil
Refill oil in the oil tank that is located on the firewall.
10.5.1.4
Venting of the lubrication system

otherwise oil would escape through the vent tube during operation. At oil level inspect, do not
exceed the max. mark.
