Refueling; Engine Oil - Honda GX120 Owner's Manual

REFUELING

Recommended Fuel
Unleaded gasoline
U.S. Pump octane rating 86 or higher
Except U.S. Research octane rating 91 or higher
Pump octane rating 86 or higher
This engine is certified to operate on unleaded gasoline with a
pump octane rating of 86 or higher (a research octane rating of 91
or higher).
Refuel in a well ventilated area with the engine stopped. If the
engine has been running, allow it to cool first. Never refuel the
engine inside a building where gasoline fumes may reach flames or
sparks.
You may use unleaded gasoline containing no more than 10%
ethanol (E10) or 5% methanol by volume. In addition, methanol
must contain cosolvents and corrosion inhibitors. Use of fuels with
content of ethanol or methanol greater than shown above may
cause starting and/or performance problems. It may also damage
metal, rubber, and plastic parts of the fuel system. Engine damage
or performance problems that result from using a fuel with
percentages of ethanol or methanol greater than shown above are
not covered under the Warranty.
If your equipment will be used on an infrequent or intermittent
basis, please refer to the fuel section of the STORING YOUR
ENGINE chapter (see page 13) for additional information regarding
fuel deterioration.
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when refueling.
• Stop the engine and keep heat, sparks, and flame
away.
• Refuel only outdoors.
• Wipe up spills immediately.
Fuel can damage paint and some types of plastic. Be careful not to
spill fuel when filling your fuel tank. Damage caused by spilled fuel
is not covered under the Distributor's Limited Warranty. Move at
least 1 meter (3 feet) away from the fueling source and site before
starting the engine.
1. With the engine stopped and on a level surface, remove the fuel
filler cap and check the fuel level. Refill the tank if the fuel level
is low.
2. Add fuel to the bottom of the maximum fuel level limit of the
fuel tank. Do not overfill. Wipe up spilled fuel before starting the
engine.

MAXIMUM
FUEL LEVEL
Refuel carefully to avoid spilling fuel. Do not fill the fuel tank
completely. It may be necessary to lower the fuel level depending
on operating conditions. After refueling, screw the fuel filler cap
back on until it clicks.
Keep gasoline away from appliance pilot lights, barbecues, electric
appliances, power tools, etc.
Spilled fuel is not only a fire hazard, it causes environmental
damage. Wipe up spills immediately.

ENGINE OIL

Oil is a major factor affecting performance and service life.
Use 4-stroke automotive detergent oil.
Recommended Oil
Use 4-stroke motor oil that meets or exceeds the requirements for
API service category SJ or later (or equivalent). Always check the
API service label on the oil container to be sure it includes the
letters SJ or later (or equivalent).
AMBIENT TEMPERATURE
SAE 10W-30 is recommended for general use. Other viscosities
shown in the chart may be used when the average temperature in
your area is within the indicated range.
