5. FUEL
RECOMMENDED MIXING RATIO GASOLINE 40 : OIL 1
HOW TO MIX FUEL
• Exhaust emission are controlled by the fundamental engine parameters
and components (eq., carburation, ignition timing and port timing) without
addition of any major hardware or the introduction of an inert material
during combustion.
• These engines are certified to operate on unleaded gasoline.
• Make sure to use gasoline with a minimum octane number of 89RON (USA/
Canada: 87AL).
• If you use a gasoline of a lower octane value than prescribed, there is a danger
that the engine temperature may rise and an engine problem such as piston
seizing may consequently occur.
• Unleaded gasoline is recommended to reduce the contamination of the air for
the sake of your health and the environment.
• Poor quality gasolines or oils may damage sealing rings, fuel lines or fuel tank
of the engine.
• Pay attention to agitation.
1. Measure out the quantities of gasoline and oil to be mixed.
2. Put some of the gasoline into a clean, approved fuel container.
3. Pour in all of the oil and agitate well.
4. Pour in the rest of gasoline and agitate again for at least one minute. As some
oils may be difficult to agitate depending on oil ingredients, sufficient agitation
is necessary for the engine to last long. Be careful that, if the agitation is insu-
fficient, there is an increased danger of early piston seizing due to abnormally
lean mixture.
5. Put a clear indication on the outside of the container to avoid mixing up with
gasoline or other containers.
6. Indicate the contents on outside of container for easy identification.
Caution:
For the mixture, never use a fuel with an ethanol percentage higher than 10 %;
gasohol (mixture of gasoline and ethanol) up to 10 % ethanol or E10 fuel are
acceptable.
