Fuel Recommendation

Servicing Your Honda
Saf ety Precautions Refer to on page .
We recommend that you use unleaded fuel because it produces fewer engine
deposits and extends the life of exhaust system components.
Your engine is designed to use any 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.
The use of leaded gas will damage the catalytic converters.
