Oil
The engine requires oil for lubricating bearings and gears. This should be mixed at 4% with the fuel and
all lubricating is then automatically metered and applied by the engine internal components.
If you use a 20ltr fuel bottle then add 0.8l of oil. For every 3 gallons of fuel add 1 pint of oil.
Some DTE oils work well in operation but leave very little slippery residue which can cause the bearings
to sound dried out after cooling. In this case we recommend the addition of 1% percent of 100%
synthetic 2 cycle oil to the 3% DTE.
To check this, simply put one drop of DTE oil between finger and thumb and rub together. You find DTE
type oils rub through very easily, whereas 2 cycle oils stay slippery very much longer.
The opposite problem exists where exclusive use of 2 cycle oil is used as it thickens up on cooling and
can cause such drag on bearings the starter cannot turn the engine for a start. So we recommend a part
% oil mix as follows:
The required total amount is
4%
of oil to be mixed with the fuel.
•
The recommended mix is a 3% of ISO32 type of oil, (commercial brands like Mobil DTE Llte,
Shell Tellus 32, Igol 32, Cepsa Turbine 32, etc)
plus 1% of 100% synthetic 2 stroke oil
.
•
Plenty of commercial brands are available locally, just check in the bottle that the oil is JASO FC
or JASO FD compliant. Commercial turbine oils like Kingtech oil, Jetcat oil, Jackadofsky oil,
Fuchs, Deluxe… can be used.
•
It is allowed to use a 5% of oil contents for compatibility with other engine brands, this will cause
a higher fuel consumption and increased possibility of internal carbon building, but is beneficial
for the gears in the gearbox.
•
Full size turbine oils can be used, but are not recommended because these oils are not intended
to be burned, irritant and contains neurotoxic chemicals such as tricresyl phosphate that in long
term could impact negatively on the health of operators and other persons breathing the exhaust
fumes. This particularly relevant to helicopters as they are often flown close to operators for
extended periods.
•
Aeroshell 500 should not be used at all due to high residues left on bearings.
•
Do not use 2 stroke oil alone (4%). This will gum the bearings causing difficult or impossible
start-up when engine is cold.
Please refer to the Xicoy Office for guidance in the first instance in event of any issue or concern.
