FUEL RECOMMENDATION
Use unleaded premium gasoline with an oc-
tane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 96).
If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rat-
ing of at least 87 AKI number (Research oc-
tane number 91) 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 acceleration.
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 the war-
ranty coverage.
• Under no circumstances should a leaded
gasoline be used, because this will dam-
age 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 contain-
ing more than 15% ethanol. Using a fuel
containing more than 15% ethanol in a
vehicle not specifically designed for a
fuel containing more than 15% ethanol
can adversely affect the emission control
devices and systems of the vehicle. Dam-
age caused by such fuel is not covered by
the INFINITI New Vehicle Limited
Warranty.
Technical and consumer information10-3

•Do not use fuel that contains the octane
booster methylcyclopentadienyl manga-
nese tricarbonyl (MMT). Using fuel con-
taining MMT may adversely affect ve-
hicle performance and vehicle emissions.
Not all fuel dispensers are labeled to in-
dicate 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 refor-
mulated 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.
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 control system and vehicle performance.
Ask your service station manager if the gaso-
line meets the 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 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 recom-
mended for unleaded gasoline.
• If an oxygenate-blend other than metha-
nol blend is used, it should contain no more
than 15% oxygenate. •
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 prob-
lems. At this time, sufficient 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, im-
mediately change to a non-oxygenate 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.
10-4Technical and consumer information

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. U.S. government regula-
tions require fuel ethanol dispensing pumps
to be identified with small, square, orange
and black label with the common abbrevia-
tion 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 Ve-
hicle (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
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 (for 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 con-
tain active solvents 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 can cause per-
sistent, heavy “spark knock.” (“Spark knock”
is a metallic rapping noise.) If severe, this can
lead to engine damage. If you detect a per-
sistent 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 that you 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 may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or en-
gine damage. If any of the above symptoms
are encountered, have your vehicle checked.
It is recommended that 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 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.
Technical and consumer 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
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 reg-
istered, its modifications, transportation,
and registration are the responsibility of the
user. INFINITI is not responsible for any in-
convenience that may result.
