Fuel Recommendation
type
pump octane number
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.
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
Use of lower octane gasoline can cause persistent ''pinging'' or ''spark
knock'' (a loud 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 Honda dealer.
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt, dust, or water in the fuel tank.
