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. Unleaded
gasoline produces fewer engine and spark plug deposits and
extends exhaust system life.
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when refueling.
Stop 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.
Never use stale or contaminated gasoline or oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
Occasionally you may hear a light ''spark knock'' or ''pinging''
(metallic rapping noise) while operating under heavy loads. This is
no cause for concern.
If spark knock or pinging occurs at a steady engine speed, under
normal load, change brands of gasoline. If spark knock or pinging
persists, see an authorized Honda servicing dealer.
Running the engine with persistent spark knock or pinging can
cause engine damage.
Running the engine with persistent spark knock or pinging is
considered misuse, and the Distributor's Limited Warranty does
not cover parts damaged by misuse.
1.
With the engine stopped and on a level surface, remove the fuel
filler cap and check the fuel level.
2.
Refill the tank if the fuel level is low. Do not fill above the upper
limit of the fuel tank. Wipe up spilled fuel before starting the
engine.

Refuel in a well-ventilated area before starting the engine. If the
engine has been running, allow it to cool. Refuel carefully to avoid
spilling fuel. Do not fill the fuel tank completely. Fill tank to the
upper limit level below the filler neck of the fuel tank to allow for
fuel expansion. It may be necessary to lower the fuel level
depending on operating conditions. After refueling, tighten the
fuel filler cap securely.
Never refuel the engine inside a building where gasoline fumes
may reach flames or sparks. 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
classification SJ, SL, or
equivalent. Always check the
API service label on the oil
container to be sure it includes
the letters SJ, SL, or equivalent.
SAE 10W-30 is recommended for general use. Other viscosities
shown in the chart may be used when the average temperature in
