Fuel Recommendation

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.
Your engine is designed to use any gasoline that has a pump octane
number of 91 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.
