Maintenance Program detailed in Section 9.1.
8.5.1 ENGINE SERVICING
For correct engine servicing and maintenance, please refer to the Rotax
Operators Manual.
8.5.2 APPROVED FUEL GRADES AND SPECIFICATIONS
The Rotax 912 and 914ULS engines require a minimum of 91 AKI
("premium"). 100LL AvGas is allowed though not preferred and reduces
the oil change interval to 25 hours in more than occasional use.
For Chinese market, in addition to 100LL AvGas, 97 octane car gas
should be used
Note: For more information, please refer to the Rotax Operator’s Manual.
8.5.3 APPROVED OIL GRADES AND SPECIFICATIONS
8.5.3.1 Oil Specifications
Rotax recommends using a high quality, major brand, 4-stroke motorcycle
oil with gear additives and “SF” or “SG” API classification. The gear
additives are required to withstand the high stresses in the reduction
gearbox. The “GL4” or “GL5” specification is recommended.
Note: For more information, please refer to the latest Rotax Operator’s
Manual.
8.5.3.2 Oil Types
Users running mostly unleaded fuel can opt for full-synthetic or semi-
synthetic oils. Users running leaded AVGAS more than 30% of the time
should only use mineral or semi-synthetic oils, since full-synthetic oil will
sludge and create residues when used with leaded fuel. Oil changes and
other important maintenance tasks have to be performed more often
when using leaded fuel, as described in the maintenance tasks table.
