2010 INFINITI FX octane

FUEL RECOMMENDATION
VK50VE 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:
●Have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as pos-
sible.
● 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
●
Using a fuel other than that specified could
adversely affect the emission control sys-
tem, 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 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 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 emission system and vehicle perfor-
mance. 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 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.
● The fuel should be unleaded and have an oc-
tane rating no lower than that recommended
for unleaded gasoline.
● If an oxygenate-blend, excepting a methanol
blend, is used, it should contain no more than
10% oxygenate. (MTBE may, however, be
added up to 15%.)

●If 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 undesirable driveability problems such as
engine stalling or hard 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 (Example: fuel injec-
tor cleaner, octane booster, intake valve de-
posit 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 above 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 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 mis-
use of the vehicle, for which INFINITI is not re-
sponsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to theengine. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer or other competent service fa-
cility.
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.
CAUTION
●
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.
● E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
● 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.

*1: Model without roof rack
*2: Model with roof rack 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 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.
INFINITI is not responsible for any inconvenience
that may result.
