2.5) Operating media-Lubricants
ATTENTION
Obey the manufacturers instructions about the lubricants.
If the engine is mainly run on AVGAS more frequent oil changes will
be required. See Service Information SI-912–016, latest edition.
Oil type
At the selection of suitable lubricants refer to the additional in-
formation in the Service Information SI-912-016, latest edition.
Oil consumption
Max. 0.06 l/h (0.13 liq pt/h)
Oil
specification
• Use only oil with RON 424 classification
• Due to the high stresses in the reduction gears, oils with gear
additives such as high performance motor cycle oils are
required.
• Because of the incorporated overload clutch, oils with friction
modifier additives are unsuitable as this could result in clutch
slippage during normal operation.
• Heavy duty 4-stroke motor cycle oils meet all the require-
ments. These oils are normally not mineral oils but semi- or
full synthetic oils.
• Oils primarily for Diesel engines have insufficient high tem-
perature properties and additives which favour clutch
slipping, and are generally unsuitable.
Oil viscosity
Use of multi-grade oils is recommended.
NOTE
Multi-viscosity grade oils are less sensitive to temperature var-
iations than single grade oils.
They are suitable for use throughout the seasons, ensure rapid
lubrication of all engine components at cold start and get less
fluid at higher temperatures.

Since the temperature range of neighboring SAE grades over-
lap, there is no need for change of oil viscosity at short duration
of ambient temperature fluctuations.
