Saf ety PrecautionsRefer to on page .
We recommend that you use unleaded fuel
because it produces fewer engine deposits
and extends the life of exhaust system
components.
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.
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.
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 .
The use of leaded gas will damage the
catalytic converter.
