Do not use any type of automotive oil. These oils have not
been blended for the purpose of air cooled aero engine
operation and will be detrimental to its operation.
12.
Use
AVGAS 100 LL
or the highest Octane Mogas above 95
containing lead. Engines not shimmed on the cylinder base
should only be run on
AVGAS.

When you change oil from the “run in” type to the “normal” oil
at or around 25 hrs replace oil filter. You may want to cut the
filter open for inspection. It is usual in Jabiru engines to find
a small amount of aluminium but definitely no metal. If
bearing metal is present contact the Jabiru Service
Department.
14.
With ignition and master OFF and throttle closed turn the
prop by hand and observe engine for odd noises or heavy
movements.
Check for regular compressions, if irregular firstly check
tappet adjustment. Operation with incorrectly adjusted
tappets with result in damage to valves, valve seats, guides
and overhead gear.
HEAD TORQUING/VALVE SETTING
Your tension wrench should be accurate. It should have had some method of calibration. They can
vary to manufacturers claims.
Engines use a 9/16 thin walled or tubed socket and a blade screwdriver.
The purpose of breaking in an engine correctly is to ensure a long reliable
life. All moving parts need freeing up especially piston rings to cylinder
walls. This is best accomplished when the greatest B.M.E.P. (Break Mean
Effective Pressure) occurs. That is at 75% power and above. Careful
monitoring by the pilot is needed during this initial period to ensure long
life of the engine and its components.
