FUEL RECOMMENDATIONS
NOTICE! Do not use unapproved gasoline, such as E85. Do not mix oil in gasoline
or modify the engine to run on alternate fuels. This can damage the engine
components. To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel.
This engine is certified to operate on unleaded gasoline with a minimum of 87
octane/87 AKI (91 RON). Use gasoline without ethanol or similar alcohol based
additives. Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl
tertiary butyl ether) may be used if required.
If the engine is routinely operated at altitudes over 5,000 ft (1,524 meters), it
will be necessary to have a qualified technician modify the engine for
increased performance. Fuel should be a minimum of 85 octane/85 AKI (91 RON)
to prevent decreased performance.
The emissions control system for this engine is EM (Engine Modifications).
1.
Use only an approved fuel container for refueling the engine.
2.
Store fuel out of direct sunlight in a cool and dry location.
3
Inspect container for fuel leaks. Replace any container that leaks.
4.
You may occasionally hear a light spark knock or pinging (metallic rapping
noise) while the engine is operating under heavy loads. This is no cause for
concern. If spark knock or pinging occurs at a steady engine speed under
normal load, switch to a premium gasoline or change brands of gasoline. If
spark knock or pinging persists, see an authorized repair centre.
5.
Never use stale or contaminated gasoline or an oil/gasoline mixture
designed for two-stroke motors.
