SERVICE INSTRUCTION
3.2) Operation with unleaded and low-lead fuel (less than 0.1 g/liter lead content)
Motor oils tested and released from BRP-Rotax (for use with unleaded fuel or MOGAS),
which we recommend for use with our ROTAX® engine types 912 i, 912 and 914 Series:
1)
according to RON 424
2)
with new formulation
3)
in red bottle
NOTE: The previous formulation of AeroShell Oil Sport Plus 4 can still be used until
its expiration date.
NOTE: The coefficient of viscosity indicates the tendency of oil to flow but it is not
necessarily a quality code. Country specific deviations of the viscosity are
possible.
3.3) Operation with leaded AVGAS fuels
Perform maintenance checks according to the latest Maintenance Manual.
More frequent oil changes will assure timely removal of residues and oil sludge thus avoiding
increased wear or operating troubles.
Motor oils tested and released by BRP-Rotax (for use with leaded AVGAS), which we rec-
ommend for use with our ROTAX® engine types 912 i, 912 and 914 Series:

WARNUNG
NOTICE
When operating primarily on unleaded fuels or MOGAS, the maintenance
intervals remain unchanged in regard to the published maintenance
schedule found in the currently valid Maintenance Manual for the engine
type.
In case of severe operating conditions (operation in cold/hot weather ar-
eas, interference by and and/or salt), the time between maintenance inter-
vals must generally be shorter, and in particular, the frequency of oil
changes must be increased regardless of the type of fuel mainly used
(MOGAS or AVGAS).
