FUEL RECOMMENDATION
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.
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-

*3: Intelligent All-Wheel Drive (AWD) models 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.
