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.
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.
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
. Synthetic oils may be used. Select the viscosity
based on the air temperature at the time of operation as
shown in the following table.
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.
A logo or symbol on oil containers identifies the API
service class and SAE viscosity grade. See Figure 3.
*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).
