10-4Technical and consumer information
FUEL INFORMATION
Use unleaded premium gasoline with an
octane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 96).
INFINITI recommends the use of unleaded
premium gasoline with 93 AKI number
(Research octane number 98) to obtain the
maximum vehicle performance and the best
driveability.
If unleaded premium gasoline is not avail-
able, unleaded regular gasoline with an
octane rating of at least 87 AKI number
(Research octane number 91) may be tem-
porarily used, but only under the following
precautions:
.Have the fuel tank filled only partially
with unleaded regular gasoline, and fill
up with unleaded premium gasoline as
soon as possible.
. Avoid full throttle driving and abrupt
acceleration.
Use unleaded premium gasoline for max-
imum vehicle performance.
CAUTION
. Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect
warranty coverage. .
Under no circumstances should a
leaded gasoline be used, because this
will damage the three-way catalyst.
. Do not use a fuel containing more
than 15% ethanol in your vehicle.
Your vehicle is not designed to run on
a fuel containing more than 15%
ethanol. Using a fuel containing more
than 15% ethanol in a vehicle not
specifically designed for a fuel con-
taining more than 15% ethanol can
adversely affect the emission control
devices and systems of the vehicle.
Damage caused by such fuel is not
covered by the INFINITI new vehicle
limited warranty.
. Do not use fuel that contains the
octane booster methylcyclopentadie-
nyl manganese tricarbonyl (MMT).
Using fuel containing MMT may
adversely affect vehicle performance
and vehicle emissions. Not all fuel
dispensers are labeled to indicate
MMT content, so you may have to
consult your gasoline retailer for
more details. Note that Federal and
California laws prohibit the use of
MMT in reformulated gasoline.
. U.S. government regulations require
ethanol dispensing pumps to be iden-
tified by a small, square, orange and black label with the common abbre-
viation or the appropriate percen-
tage for that region.
Gasoline specifications
INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter
(WWFC) specifications where it is available.
Many of the automobile manufacturers
developed this specification to improve
emission system and vehicle performance.
Ask your service station manager if the
gasoline meets the World-Wide Fuel Char-
ter (WWFC) specifications.
Reformulated gasoline
Some fuel suppliers are now producing
reformulated gasolines. These gasolines are
specially designed to reduce vehicle emis-
sions. INFINITI supports efforts towards
cleaner air and suggests that you use
reformulated gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and
methanol with or without advertising their
presence. INFINITI does not recommend the
use of fuels of which the oxygenate content
and the fuel compatibility for your INFINITI
cannot be readily determined. If in doubt, ask

your service station manager.
If you use oxygenate-blend gasoline, please
take the following precautions as the usage
of such fuels may cause vehicle performance
problems and/or fuel system damage.
.The fuel should be unleaded and have an
octane rating no lower than that re-
commended for unleaded gasoline.
. If an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 15% oxygenate.
. If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It should
also contain a suitable amount of ap-
propriate cosolvents and corrosion in-
hibitors. If not properly formulated with
appropriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or vehi-
cle performance problems. At this time,
sufficient data is not available to ensure
that all methanol blends are suitable for
use in INFINITI vehicles.
If any undesirable driveability problems such
as engine stalling or hard hot starting are
experienced after using oxygenate-blend
fuels, immediately change to a non-oxyge-
nate fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygenates can cause paint damage.
E-15 fuel
E-15 fuel is a mixture of approximately 15%
fuel ethanol and 85% unleaded gasoline. E-
15 can only be used in vehicles designed to
run on E-15 fuel. Do not use E-15 in your
vehicle. U.S. government regulations require
fuel ethanol dispensing pumps to be identi-
fied with small, square, orange and black
label with the common abbreviation or the
appropriate percentage for that region.
E-85 fuel
E-85 fuel is a mixture of approximately 85%
fuel ethanol and 15% unleaded gasoline. E-
85 can only be used in a Flexible Fuel Vehicle
(FFV). Do not use E-85 fuel in your vehicle.
U.S. government regulations require fuel
ethanol dispensing pumps to be identified
by a small, square, orange and black label
with the common abbreviation or the appro-
priate percentage for that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting
additive. INFINITI does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding the emissions control system. Note
that while some fuel pumps label MMTcontent, not all do, so you may have to
consult your gasoline retailer for more de-
tails.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel
injector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold com-
mercially. Many of these additives intended
for gum, varnish or deposit removal may
contain active solvent or similar ingredients
that can be harmful to the fuel system and
engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above can
cause persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If severe,
this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level roads,
it is recommended you have an INFINITI
retailer correct the condition. Failure to
correct the condition is misuse of the
vehicle, for which INFINITI is not respon-
sible.
Incorrect ignition timing will result in knock-
ing, after-run or overheating. This in turn
Technical and consumer information10-5

10-6Technical and consumer information
may cause excessive fuel consumption or
damage to the engine. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended you visit an
INFINITI retailer for servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see “Capacities and recommended fluids/
lubricants” (P.10-2). INFINITI recommends
the use of an energy conserving oil in order
to improve fuel economy.
Select only engine oils that meet the Amer-
ican Petroleum Institute (API) certificationor International Lubricant Standardization
and Approval Committee (ILSAC) certifica-
tion and SAE viscosity standard. These oils
have the API certification mark on the front
of the container. Oils which do not have the
specified quality label should not be used as
they could cause engine damage.Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.

If you plan to travel in another country,you
should first find out if the fuel available is
suitable for your vehicle’s engine.
Using fuel with too low an octane rating may
cause engine damage. All gasoline vehicles
must be operated with unleaded gasoline.
Therefore, avoid taking your vehicle to areas
where appropriate fuel is not available.
When transferring the registration of your
vehicle to another country, state, province
or district, it may be necessary to modify the
vehicle to meet local laws and regulations.
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications may
differ.
When any vehicle is to be taken into
another country, state, province or district
and registered, its modifications, transpor-
tation, and registration are the responsi-
bility of the user. INFINITI is not responsible
for any inconvenience that may result.
