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. To
minimize gum deposits in your fuel system and to
ensure easy starting, do notȱȱȱĞȱȱ

for the fuel to expand.
Fuel Type
For best results, use only clean, fresh, unleaded

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

however, using unleaded gasoline will require more
frequent cylinder head servicing.
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 including E20
