Oil Servicing
The oil tank is located in the engine compartment (Fig. 7-14). The capacity of oil system is 3.0-3.5 l / 0.79-0.92 U. S. gal.
Maintain required oil level in the oil tank according to the dipstick. Fill up only with suitable oil according to
specification in Chapter 2.9.2. Used oil is stated on the placard in the engine compartment.
When operating primarily on unleaded fuels or MOGAS, the maintenance intervals remain unchanged in regard to the
maintenance schedule according to the Maintenance Manual for Rotax engine type 912 Series or Rotax Service
Instructions SI-912-016, latest edition.
In the case of severe operating conditions (operation in cold/hot weather areas, interference by and/or salt), the time
between maintenance intervals 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).
When operating with leaded AVGAS fuels, perform maintenance checks according to the latest Maintenance Manual
for Rotax engine type 912 Series. 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 unleaded fuel or MOGAS and leaded AVGAS) which engine
manufacturer recommends for use with their Rotax Engine Type 912 Series are in the table below.
WARNING

WARNING
