Oil Recommendations

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 SG, SH, SJ or
higher. Select the viscosity based on the air
temperature at the time of operation as shown in the
following table.
**
*
*Use of synthetic oil having 5W-20 or 5W-30 rating is
acceptable, up to 4°C (40°F).
**Synthetic oils will provide better starting in extreme
cold below -23°C (-10°F).
Figure 2. Viscosity Grades Table.
NOTE: Using other than service class SG, SH, SJ or
higher oil or extending oil change intervals
longer than recommended can cause engine
damage.

NOTE: Synthetic oils meeting the listed classifications
may be used with oil changes performed at
the recommended intervals. However to allow
piston rings to properly seat, a new or rebuilt
engine should be operated for at least 50
hours using standard petroleum based oil
before switching to synthetic oil.
A logo or symbol on oil containers identifies the API
service class and SAE viscosity grade. See Figure 3.

Refer to "Maintenance Instructions" beginning on
page 7 for detailed oil check, oil change, and oil
filter change procedures.

Fuel Recommendations

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.
