RECOMMENDED FUEL
Use gasoline with an octane rating equal to or higher than that shown
in the table.
OCTANE RATING METHOD MINIUM
RATING
Antiknock Index (RON+MON)/2 90
Research Octane No. (RON) 98
NOTE
If knocking or pinging occurs, try a different brand of gasoline
or higher octane grade.
WARNING
Gasoline is extremely flammable and can be explosive under certain
conditions. Always stop the engine and do not smoke. Make sure
the area is well ventilated and free from any source of flame or
sparks; this includes any appliance with a pilot light.
Mixing oil inside the engine
Oil must be mixed with gasoline to lubricate the piston, cylinder,
crankshaft, and connecting rod bearings.
Recommended oil:
2-CYCLE SYNTHETIC
NOTE
If the recommended oil is not available, use only oil designed
for racing with 2-cycle engines.
Gasoline and engine oil mixing proportions:
Synthetic oil 100%: gasoline 50, engine oil 1 = 2%
Semi-synthetic oil: gasoline 50, engine oil 1 = 2%
Mineral oil: gasoline 32, engine oil 1 = 3%
CAUTION
Do not mix vegetable and mineral based oils.
Too much oil will cause excessive smoking and spark plug fouling.
Too little oil will cause engine damage or premature wear.
CAUTION
Below 0 ºC do not use 100% synthetic oil.
To prepare the mixture, first pour oil and half of the gasoline used
into a container and stir the mixture thoroughly. Then add the rest
of the gasoline and stir the mixture well
.
NOTE
At low temperature, oil will not easily mix with gasoline. Take
time to ensure a well-blended mixture.
The lubrication quality of this mixture deteriorates rapidly; use
a fresh mixture for each day of operation.
