FUEL AND OIL RECOMMENDATIONS
Fuel
Use only clean, fresh, unleaded regular grade
gasoline.
CAUTION
Do not mix oil with gasoline.
Octane Rating
The octane rating of a gasoline is a measure of
its resistance to “knocking”. Using a minimum of 87
octane by the antiknock index is recommended. The
antiknock index is posted on service station pumps
in the U.S.A.
Antiknock Index: (RON + MON)/2
RON = Research Octane Number
MON = Motor Octane Number
NOTE
○If “knocking or pinging” occurs, use a different
brand of gasoline or higher octane rating.
Oxygenated Fuel
Oxygenates (either ethanol or MTBE) are added
to the gasoline. If you use the oxygenated fuel be
sure it is unleaded and meets the minimum octane
rating requirement.
The following are the EPA approved percentages
of fuel oxygenates.
ETHANOL: (Ethyl or Grain Alcohol)
You may use gasoline containing up to 10%
ethanol by volume.
MTBE: (Methyl Tertiary Butyl Ether)
You may use gasoline containing up to 15% MTBE
by volume.
METHANOL: (Methyl or Wood Alcohol) 5% by vol-
ume
You may use gasoline containing up to 5%
methanol by volume, as long as it also contains
cosolvents and corrosion inhibitors to protect the
fuel system. Gasoline containing more than 5%
methanol by volume may cause starting and/or
performance problems. It may also damage metal,
rubber, and plastic parts of your fuel system.
