if ignited. Store gasoline only in approved containers, in
well ventilated, unoccupied buildings, away from sparks or
Ěǯȱȱȱęȱȱȱȱȱȱȱȱȱȱ
running, since spilled fuel could ignite if it comes in contact
with hot parts or sparks from ignition. Do not start the
engine near spilled fuel. Never use gasoline as a cleaning
agent.
General Recommendations
Purchase gasoline in small quantities and store
in clean, approved containers. A container with a
¢ȱȱŘȱȱȱȱȱȱȱȱȱ
recommended. Such a container is easier to handle
and helps eliminate spillage during refueling.
To ensure easy starting and minimize gum deposits in

Fuel Type

gasoline with a pump sticker octane rating of 86 or
ǯȱȱȱȱȱȱǰȱȱ
should be 90 octane minimum.
Unleaded gasoline is recommended, as it leaves less
combustion chamber deposits. Leaded gasoline may
be used in areas where unleaded is not available
and exhaust emissions are not regulated. Be aware
however, using unleaded gasoline will require more
frequent cylinder head servicing.
