Some conventional gasolines are
being blended with alcohol or an
ether compound. These gasolines
are collectively ref erred to as
oxygenated f uels. To meet clean air
standards, some areas of the United
States and Canada use oxygenated
f uels to help reduce emissions.
If you use an oxygenated f uel, be
sure it is unleaded and meets the
minimum octane rating requirement.
Bef ore using an oxygenated f uel, try
to conf irm the f uel’s contents. Some
states/provinces require this
informationtobepostedonthe
pump.The f ollowing are the U.S. EPA and
Canadian CGSB approved
percentages of oxygenates:
If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
Fuel system damage or perf ormance
problems resulting f rom the use of
an oxygenated f uel containing more
than the percentages of oxygenates
given above are not covered under
warranty.
(Methyl Tertiary Butyl
Ether)
You may use gasoline containing up
to 15 percent MTBE by volume. (ethyl or grain alcohol)
You may use gasoline containing up
to 10 percent ethanol by volume.
Gasoline containing ethanol may be
marketed under the name ‘‘Gasohol.’’
(methyl or wood
alcohol)
Your car was not designed to use
fuel that contains methanol.
Methanol can corrode metal parts in
the fuel system, and also damage
plastic and rubber components. This
damage would not be covered by
your warranties. MT BE ET HA NOL

If you are planning to take your
Honda outside the U.S. or Canada,
contact the tourist bureaus in the
areas you will be traveling in to f ind
out about the availability of unleaded
gasoline with the proper octane
rating.
If unleaded gasoline is not available,
be aware that using leaded gasoline
in your Honda will af f ect perf or-
mance and fuel mileage, and damage
its emissions controls. It will no
longer comply with U.S. and
Canadian emissions regulations, and
will be illegal to operate in North
America. To bring your car back into
compliance will require the replace-
ment of several components, such as
theoxygensensorsandthethree
way catalytic converter. These re-
placements are not covered under
warranty.

The emissions control systems are
covered by warranties separate from
the rest of your car. Read your
warranty manual f or more informa-
tion. The emissions control systems are
designed and certif ied to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
genuine Honda replacement parts or
their equivalent f or repairs. Using
lowerqualitypartsmayincreasethe
emissions f rom your car.
The PGM-FI System uses sequential
multiport f uel injection.
It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
The Engine Control Module (ECM)
or the Powertrain Control Module
(PCM) uses various sensors to
determine how much air is going
into the engine. It then controls how
much f uel to inject under all operat- ing conditions.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust emissions controls
include f our systems: PGM-FI,
Ignition Timing Control, Exhaust
Gas Recirculation and Three Way
Catalytic Converter. These four
systems work together to control the
engine’s combustion and minimize
the amount of HC, CO, and NOx that
comes out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems. The Exhaust Gas Recirculation
(EGR) system takes some of the
exhaust gas and routes it back into
the intake manif old. Adding exhaust
gas to the air/f uel mixture reduces
the amount of NOx produced when
the f uel is burned.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), dinitrogen
(N ), and water vapor.
