zyxwvut
Using the proper type and weight of oil in the crankcase
is extremely important. So is checking oil daily and
changing oil regularly. Failure to use the correct oil, or
using dirty oil, causes premature engine wear and
failure.
Oil Type
Use high quality detergent oil of API (American
Petroleum Institute) service class S G g SH, SJ or
higher. Select the viscosity based on the air
temperature at the time of operation as shown in the
following table.

TEMPERATURE RANGE EXPECTED BEFORE NEXT OIL CHANGE
*Use of synthetic oil having 5W-20 or 5W-30 rating is acceptable,
**Synthetic oils will provide better starting in extreme cold
up to 4OoF.
(below -1 OOF).

NOTE: Using other than service class SG, SH, SJ or
higher oil or extending oil change intervals
longer than recommended can cause engine
damage.
A logo or symbol on oil containers identifies the API
service class and SAE viscosity grade. See Figure 4.

Fuel Recommendations

WARNING: Explosive Fuel!
zyx
Gasoline is extremely flammable and its vapors can
explode if ignited. Store gasoline only in approved
containers, in well ventilated, unoccupied buildings,
a way 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
insure 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. 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 se rvice.
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.
