Servicing Your Honda
Fuel
Refer to Safety Precautions on page 45.
Your engine is designed to use any unleaded
gasoline that has a pump octane number of 86
or higher. Gasoline pumps at service stations
normally display the pump octane number. For
information on the use of oxygenated fuels, see
page 158.
Use of lower octane gasoline can cause
persistent ‘‘pinging’’ or ‘‘spark knock’’ (a
louder rapping noise) which, if severe, can lead
to engine damage. (Light pinging experienced
while operating under a heavy load, such as
climbing a hill, is no cause for concern.)
If pinging or spark knock occurs at a steady
engine speed under normal load, change brands
of gasoline. If pinging or spark knock persists,
consult your dealer.
Use only unleaded fuel in your Honda. If you
ride your Honda in a country where leaded fuel
might be available, take precautions to use only
unleaded fuel.
Never use stale or contaminated gasoline or an
oil/gasoline mixture. Avoid getting dirt, dust, or
water in the fuel tank.
