FUEL RECOMMENDATION
VK45DE engine
Use unleaded premium gasoline with an octane
rating of at least 91 AKI (Anti-Knock Index)
number (Research octane number 96).
If premium gasoline is not available, unleaded
regular gasoline with an octane rating of 87 AKI
number (Research octane number 91) may be
temporarily used, but only under the following
precautions:
cHave the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as pos-
sible.
c Avoid full throttle driving and abrupt accel-
eration.
However, for maximum vehicle performance, the
use of unleaded premium gasoline is recom-
mended.
VQ35HR engine
INFINITI recommends the use of unleaded pre-
mium gasoline with an octane rating of at least
91 AKI (Anti-Knock Index) number (Research
octane number 96).
If unleaded premium gasoline is not available,
you may use unleaded regular gasoline with an octane rating of at least 87 AKI number (Re-
search octane number 91), but you may notice a
decrease in performance.
CAUTION
c
Using a fuel other than that specified could
adversely affect the emission control sys-
tem, and may also affect warranty coverage.
c Under no circumstances should a leaded
gasoline be used, because this will damage
the three-way catalyst.
c Do not use E-85 fuel in your vehicle. Your
vehicle is not designed to run on E-85 fuel.
Using E-85 fuel can damage the fuel system
components and is not covered by the
INFINITI new vehicle limited warranty.
Gasoline specifications
INFINITI recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifica-
tions where it is available. Many of the automo-
bile manufacturers developed this specification
to improve the emission control system and
vehicle performance. Ask your service station
manager if the gasoline meets the WWFC speci-
fications.
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 gaso-
line when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and metha-
nol with or without advertising their presence.
INFINITI does not recommend the use of fuels of
which the oxygenate content and the fuel com-
patibility 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 prob-
lems and/or fuel system damage.
c The fuel should be unleaded and have an oc-
tane rating no lower than that recommended
for unleaded gasoline.
c If an oxygenate-blend other than methanol
blend is used, it should contain no more than
10% oxygenate. (MTBE may, however, be
added up to 15%.)
9-4Technical and consumer information
wÐ

cIf a methanol blend is used, it should contain
no more than 5% methanol (methyl alcohol,
wood alcohol). It should also contain a suit-
able amount of appropriate cosolvents and
corrosion inhibitors. If not properly formu-
lated with appropriate cosolvents and corro-
sion inhibitors, such methanol blends may
cause fuel system damage and/or vehicle
performance problems. At this time, suffi-
cient data is not available 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, imme-
diately change to a non-oxygenate 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-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. govern-
ment regulations require fuel ethanol dispens-
ing pumps to be identified by a small, square, orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (for example, fuel
injector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold commer-
cially. 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 can cause persistent,
heavy ªspark knockº. (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,
have an INFINITI retailer correct the condition.
Failure to correct the condition is misuse of the
vehicle, for which INFINITI is not responsible.
Incorrect ignition timing will result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or enginedamage. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is not a cause for con-
cern, because you get the greatest fuel benefit
when there is light spark knock for a short time
under heavy engine load.
CAUTION
c
Your vehicle is not designed to run on E-85
fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.
c E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
c U.S. government regulations require ethanol
dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.

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 sat-
isfactory engine life and performance, see ªCA-
PACITIES AND RECOMMENDED
FUEL/LUBRICANTSº earlier in this section.
INFINITI recommends the use of an energy
conserving oil in order to improve fuel economy.Select only engine oils that meet the American
Petroleum Institute (API) certification or Interna-
tional Lubricant Standardization and Approval
Committee (ILSAC) certification and SAE viscos-
ity standard. These oils have the API certifica-
tion 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.
Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant to select the engine oil viscosity based on
the temperatures at which the vehicle will be
operated before the next oil change. Choosing
an oil viscosity other than that recommended
could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When replac-
ing, use the genuine oil filter or its equivalent
for the reason described in ªChange intervalsº.
Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Using engine oil and a
filter other than the specified quality, or exceed-
ing recommended oil and filter change intervals
could reduce engine life. Damage to the engine
caused by improper maintenance or use of
incorrect oil and filter quality and/or viscosity is
not covered by the INFINITI new vehicle limited
warranty.

Your engine was filled with a high quality
engine oil when it was built. You do not have to
change the oil before the first recommended
change interval. Oil and filter change intervals
depend upon how you use your vehicle.
Operation under the following conditions may
require more frequent oil and filter changes.
crepeated short distance driving at cold out-
side temperatures,
c driving in dusty conditions,
c extensive idling,
c stop and go commuting
Refer to the ªINFINITI Service and Maintenance
Guideº for the maintenance schedule.
AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONS
The air conditioning system in your INFINITI ve-
hicle must be charged with the refrigerant HFC-
134a (R-134a) and the oil, NISSAN A/C system oil
Type S or the exact equivalents.
CAUTION
The use of any other refrigerant or oil will cause
severe damage to the air conditioning system
and will require the replacement of all air con-
ditioner system components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth's ozone
layer. Although this refrigerant does not affect
the earth's atmosphere, certain governmental
regulations require the recovery and recycling
of any refrigerant during automotive air condi-
tioning system service. Your INFINITI retailer
has the trained technicians and equipment
needed to recover and recycle your air condi-
tioning system refrigerant.
Contact an INFINITI retailer when servicing your
air conditioning system.

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 ve-
hicles must be operated with unleaded gaso-
line. Therefore, avoid taking your vehicle to
areas where appropriate fuel is not available.
When transferring the registration of your ve-
hicle to another country, state, province or dis-
trict, 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 regis-
tered, its modifications, transportation, and reg-
istration are the responsibility of the user.
