Fuel Recommendations

WARNING: Explosive Fuel!
Gasoline is extremely flammable and its vapors can explode if
ignited. Store gasoline only in approved containers, in well
ventilated, unoccupied buildings, away from sparks or flames.
Do not fill the fuel tank while the engine is hot or 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
capacity of 2 gallons or less with a pouring spout is
recommended. Such a container is easier to handle and
helps eliminate spillage during refueling.
Do not use gasoline left over from the previous season,
to minimize gum deposits in your fuel system and to
ensure easy starting.
Do not add oil to the gasoline.
Do not overfill the fuel tank. Leave room for the fuel to
expand.
Fuel Type
For best results use only clean, fresh, unleaded gasoline
with the pump sticker octane rating of 87 or higher. In
countries using the Research method, it should be 90
octane minimum.
Unleaded gasoline is recommended as it leaves less
combustion chamber deposits and reduces harmful
exhaust emissions. Leaded gasoline is not
recommended.
Gasoline/Alcohol blends
Gasohol (up to 10% ethyl alcohol, 90% unleaded
gasoline by volume) is approved as a fuel for Kohler
engines. Other gasoline/alcohol blends are not
approved.
Gasoline/Ether blends
Methyl Tertiary Butyl Ether (MTBE) and unleaded
gasoline blends (up to a maximum of 15% MTBE by
volume) are approved as a fuel for Kohler engine.
Other gasoline/ether blends are not approved.
Engine Identification Numbers
When ordering parts, or in any communication
involving an engine, always give the Model,
Specification, and Serial Numbers of the engine.
The engine identification numbers appear on a decal
(or decals) affixed to the engine shrouding. Include
letter suffixes, if there are any.
Record your engine identification numbers on the
identification label (Figure 4) for future reference.
