type
pump
octane number
We recommend that you use unleaded fuel because it produces fewer engine
deposits and extends the life of exhaust system components.
The use of leaded gas will damage the catalytic converters.
Your engine is designed to use any gasoline that has a pump octane number of
92 or higher. Gasoline pumps at service stations normally display the pump
octane number. For information on the use of oxygenated fuels, see page 184.
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.
