Fuel Recommendations - Honda WB20X Owner's Manual

SERVICING YOUR PUMP
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 above the fuel strainer shoulder. After refu
tighten the fuel tank 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.
p m q
Fuel can damage paint and plastic. Be careful not to spill fuel when
filling your fuel tank. Damage caused by spilled fuel is not covered
under warranty.
FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump octane rating of 86
or
higher.
These engines are certified to operate on unleaded gasoline. Unleaded
gasoline produces fewer engine and spark plug deposits and extends
exhaust system life.
Never use stale or contaminated gasoline or an 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 misuse,
and the Distributor's Limited Warrantydoes not cover parts damaged
by misuse.
