Max. 0.06 l/h (0.13 liq pt/h).
- Use only oil with API classification "SG" or higher!
- Due to the high stresses in the reduction gears, oils with gear
additives such as high performance motor cycle oils are requi-
red.
- Because of the incorporated overload clutch, oils with friction
modifier additives are unsuitable as this could result in a slip-
ping clutch 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 primarity for Diesel engines have insufficient high tem-
perature properties and additives which favour clutch
slipping, and are generally unsuitable.
Use of multi-grade oils is recommended.
NOTE: Multi-viscosity grade oils are less sensitive to
temperature variations than single grade oils.
They are suitable for use throughout the sea-
sons, ensure rapid lubrication of all engine com-
ponents at cold start and get less fluid at higher
temperatures.

Obey the manufacturers instructions about
the lubricants.
If the engine is mainly run on AVGAS more
frequent oil changes will be required. See

tion.

mation SI-912-016, latest edition.
