Fuel
Remove the filler cap and check the fuel level. Refill the tank if the fuel
level is low. Do not fill above the UPPER LEVEL line.
Your engine is designed t o use any gasoline that has a pump octane
number
( 7 )
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 t o 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 concern, it simply means your engine is
operating efficiently.
