Fuel Recommendation
type
research octane number
Use only unleaded fuel in your Honda. The use of leaded fuel will
damage the catalytic converter(s). 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 petrol that has a pump
octane number (R + M)/2 of 86 or higher, or a research octane
number of 91 or higher. Petrol pumps at service stations normally
display the pump octane number. For information on the use of
Petrol Containing Alcohol, see page 210.
Use of lower octane petrol 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 petrol. If pinging or spark knock
persists, consult your dealer.
Never use stale or contaminated petrol or an oil/petrol mixture.
Avoid getting dirt, dust, or water in the fuel tank.
