FUEL AND OIL
Fuel Requirements
NOTICE
Always use fresh gaso-
line. Gasoline will oxidize; the re-
sult is loss of octane, volatile com-
pounds, and the production of gum
and varnish deposits which can
damage the fuel system.
Alcohol fuel blending varies by coun-
try and region. Your vehicle has been
designed to operate using the recom-
mended fuels, however, be aware of
the following:
– Use of fuel containing alcohol above
the percentage specified by gov-
ernment regulations is not recom-
mended and can result in the fol-
lowing problems in the fuel system
components:
• Starting and operating difficul-
ties.
• Deterioration of rubber or plastic
parts.
• Corrosion of metal parts.
• Damage to internal engine parts.
– Inspect frequently for the presence
of fuel leaks or other fuel system
abnormalities if you suspect the
presence of alcohol in gasoline ex-
ceeds the current government reg-
ulations.
– Alcohol blended fuels attract and
hold moisture which may lead to
fuel phase separation and can result
in engine performance problems or
engine damage.
Recommended Fuel
Use unleaded gasoline containing MA-
XIMUM 10% ethanol. The gasoline
must have the following minimum oc-
tane requirements:

NOTICE
Never experiment with
other fuels. Engine or fuel system
damages may occur with the use of
an inadequate fuel.
NOTICE
Do NOT use fuel from fuel
pumps labeled E85.
Use of fuel labeled E15 is prohibited by
U.S. EPA Regulations.
Fuel Antifreeze Additives
When using oxygenated fuel, addi-
tional gas line antifreeze or water ab-
sorbing additives are not required and
should not be used. When using non
oxygenated fuel, isopropyl base gas
line antifreeze can be used in a propor-
tion of 150 ml (5 U.S. oz) of gas line an-
tifreeze added to 40 L (10.6 U.S. gal.)
of gas.
This precaution is in order to reduce the
risk of frost buildup in carburetors or
other fuel system components which
may lead, in certain cases, to severe
damage to engine.
NOTE: Use only methyl hydrate free
gas line antifreeze.
