.
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.
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt, dust, or water in the fuel tank.
