LUBRICANTS AND CAPACITIES
10-2Technical and consumer information

FUEL RECOMMENDATION
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 gaso-
line is not available, you may use unleaded regular
gasoline with an octane rating of at least 87 AKI
number (Research octane number 91) , but you
may notice a decrease in performance.
CAUTION
●Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect the
warranty coverage.
● Under no circumstances should a
leaded gasoline be used, because this
will damage 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 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 la-
beled to indicate MMT content, so you
may have to consult your gasoline re-
tailer for more details. Note that Fed-
eral 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 abbrevia-
tion or the appropriate percentage for
that region.
Gasoline specifications
INFINITI recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifi-
cations where it is available. Many of the automo-
bile manufacturers developed this specification
to improve emission control system and vehicle
performance. Ask your service station manager if
the gasoline meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing reformu-
lated gasolines. These gasolines are specially designed to reduce vehicle emissions. INFINITI
supports efforts towards cleaner air and sug-
gests that you use reformulated gasoline when
available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing oxy-
genates 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 com-
patibility for your INFINITI cannot be readily de-
termined. 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
recommended for unleaded gasoline.
● If an oxygenate-blend other than
methanol blend is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
10-4Technical and consumer information

●E-15 fuel contains more than 10% oxy-
genate. E-15 fuel will adversely affect
the emission control devices and sys-
tems of the vehicle and should not be
used. Damage caused by such fuel is
not covered by the INFINITI New Ve-
hicle Limited Warranty.
● 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 appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents 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 ve-
hicles.
If any driveability problems such as engine stall-
ing and difficult hot-starting are experienced after
using oxygenate-blend fuels, immediately
change to a non-oxygenate fuel or a fuel with a
low blend of MTBE.
Take care not to spill gasoline during refu-
eling. 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. gov-
ernment regulations require fuel ethanol dispens-
ing pumps to be identified with small, square,
orange and black label with the common abbre-
viation 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 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 appropriate percentage for that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manganese tri-
carbonyl, is an octane boosting additive. INFINITI
does not recommend the use of fuel containing
MMT. Such fuel may adversely affect vehicle per-
formance, including the emissions control sys-
tem. 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 (for example, fuel injec-
tor cleaner, octane booster, intake valve deposit
removers, etc.) which are sold commercially.
Many of these additives intended for gum, varnish
or deposit removal may contain active solvents 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 “spark knock.” (“Spark
knock” is a metallic rapping noise.) If se-
vere, 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 that you have an
INFINITI retailer correct the condition. Fail-
ure to correct the condition is misuse of the
vehicle, for which INFINITI is not respon-
sible.
Technical and consumer information10-5

Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked. It is rec-
ommended that you visit 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 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
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade, quality
and viscosity engine oil to ensure satisfactory
engine life and performance. For additional infor-
mation, refer toRecommended fluids/lubricants
and capacities in this section. INFINITI recom-
mends 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 vis-
cosity 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 ad-
ditives. 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.

10-6Technical and consumer information

When planning to drive your INFINITI ve-
hicle in another country,you should first find
out if the fuel available is suitable for your vehi-
cle’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. There-
fore, 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 emis-
sion control and safety standards vary according
to the country, state, province or district; there-
fore, vehicle specifications may differ.
When any vehicle is to be taken into an-
other country, state, province or district and
registered, its modifications, transporta-
tion, and registration are the responsibility
of the user. INFINITI is not responsible for
any inconvenience that may result.
