2003 Acura MDX fuel

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:
(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 vehicle 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. 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.

If you are planning to take your
Acura outside the U.S., contact the
tourist bureaus in the areas you will
betravelingintofindoutaboutthe
availability of unleaded gasoline with
theproperoctanerating.
If unleaded gasoline is not available,
be aware that using leaded gasoline
in your Acura 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 vehicle back
into compliance will require the re-
placement of several components,
such as the oxygen sensors and the
three way catalytic converter. These
replacements are not covered under
warranty.

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 emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual f or more informa-
tion.
The PGM-FI System uses sequential
multiport f uel injection.
It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
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 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.
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
Acura replacement parts or their
equivalent f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.
