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, 915 i, 912 and 914 
Series:

1)

 according to RON 424

2)

 with new formulation

Specification RON 424

: The ROTAX® Norm 424 (RON 424) is a BRP-Rotax internal standard, 

which is only available on special request via the ROTAX® Authorized Distributor and will not be 
disclosed to third parties without prior consent.

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.

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).
