Oil Recommendations

Using the proper type and weight of oil in the engine
is extremely important, as is daily checking of oil level
and changing oil regularly. Failure to use the correct
oil, or using dirty oil, will cause premature engine
wear and failure.

Oil Type

Use high-quality oil that ranks at or above the
American Petroleum Institute's (API) SJ service class.
Select the oil's viscosity based on air temperature at
the time of operation, as shown in the viscosity grades
table.
Recommended SAE Viscosity Grades
Kohler 10W-30
10W-30
5W-30
°F 0 10 20 32
°C -17 -12 -6 0
Use service class SJ rated oil or higher. Do not extend
the oil change intervals longer than recommended,
as this can cause engine damage and may void
the warranty. An API symbol on the oil container
identifies the service class and SAE viscosity grade.
Fuel Recommendations
Explosive Fuel can cause fires
and severe burns.
Do not fill the fuel tank while the
engine is hot or running.
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.

WARNING

General Fuel Recommendations

1
See Figure
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 not use gasoline left over from
the previous season.
Do not add oil to the gasoline.
Do not overfill the fuel tank (C). Leave room for the
fuel to expand.

Fuel Type

For best results use only clean, fresh, unleaded
gasoline with an 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, including E20
and E85, should not be used. 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.

Fuel Line

These engines use Low Permeation SAE 30 R7 rated
fuel lines, certified to meet emission requirements.
Standard fuel lines may not be used. Order
replacement hose through a Kohler Service Center.
