SERVICING
ENGINE OIL
Servicing the oil of the Rotax
®
912 engine is dependant mainly upon two factors: fuel
type and engine operation temperature. Because of the high lead content, 100LL
Avgas deposits a residue leading to operation difficulties more frequently when Rotax
®
engines are operated with leaded Avgas fuels. The lead contained in Avgas will
deposit in the piston rings and in the rocker arms of the valve train. Use Avgas only
while traveling when unleaded fuel is not available. When you return from traveling,
change the oil to help eliminate the lead from the engine.
‘MoGas’, motor fuel, available at some airports, is not a suitable fuel. The octane
rating for MoGas is usually only 87 and therefore may cause detonation during engine
operation.
Therefore, specific oil types coincide with fuel types and engine temperatures. Fig. 9-
1 lists the oil types recommended for use with unleaded fuels. Fig. 9-2 lists the oil
types recommended for use with leaded fuels. The information provided in these
figures is in accordance with Rotax
®
Service Instruction SI-18-1997 R5.
This
instruction or its latest revision should be followed by the owner/pilot.
