FUEL RECOMMENDATION
INFINITI recommends the use of unleaded
premium gasoline with an octane rating of at
least 91 AKI (Anti-Knock Index) number (Re-
search octane number 95).
If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rat-
ing of at least 89 AKI number (Research oc-
tane number 93) may be temporarily 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 ac-
celeration.
Use unleaded premium gasoline for maxi-
mum vehicle performance.
CAUTION
•Using a fuel other than that specified
could adversely affect the emission con-
trol system, and may also affect war-
ranty coverage.
•Under no circumstances should a leaded
gasoline be used, because this will dam-
age the three-way catalyst.
•Do not use E-15 or E-85 fuel in your
vehicle. Your vehicle is not designed to
run on E-15 or E-85 fuel. Using E-15 or
E-85 fuel in a vehicle not specifically de-
signed for E-15 or E-85 fuel can ad-
versely affect the emission control de-
vices and systems of the vehicle.
Damage caused by such fuel is not cov-
ered by the INFINITI New Vehicle Lim-
ited Warranty.
•Do not use fuel that contains the octane
booster methylcyclopentadienyl man- ganese tricarbonyl (MMT). Using fuel
containing MMT may adversely affect
vehicle performance and vehicle emis-
sions. 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 identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage for that
region.
Technical information10-3

Gasoline specifications
INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter
(WWFC) specifications where it is available.
Many of the automobile manufacturers de-
veloped this specification to improve emis-
sion system and vehicle performance. Ask
your service station manager if the gasoline
meets the World-Wide Fuel Charter
(WWFC) specifications.
Reformulated gasoline
Some fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
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 usageof 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 recom-
mended for unleaded gasoline.
•If an oxygenate-blend, other than a
methanol blend, is used, it should contain
no more than 10% oxygenate. (MTBE
may, however, be added up to 15%.)
•E-15 fuel contains more than 10% oxy-
genate. E-15 fuel will adversely affect the
emission control devices and systems of
the vehicle and should not be used. Dam-
age caused by such fuel is not covered by
the INFINITI New Vehicle Limited War-
ranty.
•If a methanol blend is used, it should con-
tain no more than 5% methanol (methyl
alcohol, wood alcohol). It should also con-
tain a suitable amount of appropriate co-
solvents and corrosion inhibitors. If not
properly formulated with appropriate co-
solvents and corrosion inhibitors, such
methanol blends may cause fuel system
damage and/or vehicle performance
problems.
At this time, sufficient data is not avail-
able to ensure that all methanol blends
are suitable for use in INFINITI vehicles. If any driveability problems such as engine
stalling and difficult hot-starting are experi-
enced after using oxygenate-blend fuels, im-
mediately change to a nonoxygenate fuel or a
fuel with a low blend of MTBE.
Take care not to spill gasoline during refuel-
ing. 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 la-
bel with the common abbreviation or the ap-
propriate 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 Ve-
hicle (FFV). Do not use E-85 fuel in your
vehicle. U.S. government regulations require
fuel ethanol dispensing pumps to be identi-
fied by a small, square, orange and black label
with the common abbreviation or the appro-
priate percentage for that region.
10-4Technical information

Fuel containing MMT
MMT, or methylcyclopentadienyl manganese
tricarbonyl, is an octane boosting additive.
INFINITI does not recommend the use of fuel
containing MMT. Such fuel may adversely
affect vehicle performance, including the
emissions control system. Note that while
some fuel pumps label MMT content, not all
do, so you may have to consult your gasoline
retailer for more details.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel in-
jector 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 con-
tain active solvent or similar ingredients that
can be harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rat-
ing 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 recom-mended you have an INFINITI retailer cor-
rect the condition. Failure to correct the con-
dition is misuse of the vehicle, for which
INFINITI is not responsible.
Incorrect ignition timing will result in knock-
ing, after-run and/or overheating. This in turn
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.
However, now and then you may notice light
spark knock for a short time while accelerat-
ing 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.

RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure sat-
isfactory engine life and performance. For
additional information, refer to "Recom-
mended fluids/lubricants and capacities"
earlier in this section.
Select only engine oils that meet the
MB229.5 specification and SAE viscosity
standard. These oils have the MB229.5
specification label on the container. Oils
which do not have the specified quality label
should not be used as they could cause en-
gine 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.
Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant that the engine oil viscosity be selected
Technical information10-5

When planning to drive your INFINITI VE-
HICLE in another country, you should first
find out if the fuel available is suitable for
your vehicle's engine.
Using fuel with an octane rating that is too
low 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 avail-
able.
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, the vehicle specification
may differ.
When any vehicles are to be taken into an-
other country, state, province or district, its
modification, transportation, registration,
and any other expenses which may result,
are the responsibility of the user. INFINITI is
not responsible for any inconveniences that
may result. It is prohibited to cover, paint, weld, cut, drill,
alter or remove the Vehicle Identification
Number (VIN).
