Fuel System
Refer to Safety Precautions on page 25.
Fuel Recommendation
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 petrol that has
a pump octane number (R+M)/2 of 91 or higher,
or a research octane number of 95 or higher.
Petrol pumps at service stations normally display
the pump octane number. For information on the
use of Petrol Containing Alcohol, see page 158.
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 Honda dealer.
Never use stale or contaminated petrol or an
oil/petrol mixture. Avoid getting dirt, dust, or
water in the fuel tank.
