2.23.3 LUBRICANTS
Oil: Motorcycle oil of a registered brand with gear additives. If using aircraft engine oil; than only a
blended one.
Oil specification:
•
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 required.
•
Because of the incorporated friction clutch, oils with friction modifier additives are unsuitable as this
could result in a slipping clutch during normal operation.
•
Heavy duty 4-stroke motor cycle oils meet all the requirements. These oils are normally no mineral
oils but semi or full synthetic oils.
•
Oils primarily for Diesel engines are due to insufficient high temperature properties and
additives which favour clutch slipping, generally unsuitable.
•
CAUTION:
If the engine is mainly run on AVGAS more frequent oil changes will be required.
Oil consumption: max 0,06 l/h (0.13 liq pt/h)
Oil viscosity: 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 seasons, ensure rapid lubrication of all engine
components at cold start and get less fluid at higher temperatures.
Table of lubricants
Since the temperature range of neighbouring SAE grades overlap, there is no need for change of oil
viscosity at short duration of ambient temperature fluctuations.
