6.2 Fuel Recommendations
General Recommendations
6.2.1
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.
To minimize gum deposits in your fuel system and to insure easy starting, do not use gasoline left
over from the previous season.
Do not add oil to the gasoline.
Do not over-fill the fuel tank. Leave room for the fuel to expand.
Fuel Type
6.2.2
For best results use only clean, fresh, unleaded gasoline with a 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. Leaded
gasoline may be used in areas where unleaded is not available and exhaust emissions are not
regulated. Be aware, however, that the cylinder heads may require more frequent service.
Gasoline/Alcohol Blends
6.2.3
Gasoline (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
6.2.4
Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up to maximum of
15% MTBE by volume) are approved as a fuel for Kohler engines. Other gasoline/ether blends are
not approved.
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.
