Fuel Recommendation
type
pump octane number
Use only unleaded fuel in your Honda. The use of leaded fuel will
damage the catalytic converter(s). If you drive 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 (USA & Canada only), see page 294.
For information on the use of Petrol Containing Alcohol (Australia &
New Zealand only), see page 296.
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 dealer.
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt, dust, or water in the fuel tank.
