repair establishment or individual; however, warranty repairs must be performed by a Kohler authorized
service center.
Fuel Type
For best results use only clean, fresh, unleaded
gasoline with a pump sticker octane rating of 87

must not be used on EFI engines or on other models
where exhaust emissions are regulated.
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
and E85 are not to be used and not approved. Any
failures resulting from use of these fuels will not be
warranted.
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 engines.
Other gasoline/ether blends are not approved.
