2. Fuel
Remove the filler cap and check the fuel level. Refill the tank if the fuel level is low.
Do not fill above the shoulder of the fuel filter.
Your engine is designed to use any gasoline that has a pump octane number (y)
of 86 or higher, or that has a research octane number of 91 or higher. Gasoline pumps
at service station normally display the pump octane number.
We recommend that you use unleaded fuel because it produces fewer engine and spark
plug deposits and extends the life of exhaust system components.
Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting
dirt, dust or water in the fuel tank. Use of a lower octane gasoline can cause persistent
"pinging" or heavy "spark knock" (a metallic rapping noise) which, if severe, can lead
to engine damage.
CAUTION: If "spark knock" or "pinging" occurs at a steady engine speed under
normal load, change brands of gasoline. If spark knock or pinging persists, consult
your authorized Honda dealer. Failure to do so is considered misuse, and damage
caused by misuse is not covered by Honda's Limited Warranty.
Occasionally you may experience light spark knock while operating under heavy loads.
This is no cause for cnocern, it simply means your engine is operating efficiently.
