FUEL INFORMATION
Use unleaded premium gasoline with an
octane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 96).
INFINITI recommends the use of unleaded
premium gasoline with 93 AKI number
(Research octane number 98) to obtain the
maximum vehicle performance and the best
driveability.
If unleaded premium gasoline is not avail-
able, unleaded regular gasoline with an
octane rating of at least 87 AKI number
(Research octane number 91) may be tem-
porarily 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 max-
imum vehicle performance.
CAUTION
. Using a fuel other than that specified
could adversely affect the emission
control system, 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 a fuel containing more
than 15% ethanol in your vehicle.
Your vehicle is not designed to run on
a fuel containing more than 15%
ethanol. Using a fuel containing more
than 15% ethanol in a vehicle not
specifically designed for a fuel con-
taining more than 15% ethanol can
adversely affect the emission control
devices and systems of the vehicle.
Damage caused by such fuel is not
covered by the INFINITI’s New Vehi-
cle Limited Warranty.
. Do not use fuel that contains the
octane booster methylcyclopentadie-
nyl manganese tricarbonyl (MMT).
Using fuel containing MMT may
adversely affect vehicle performance
and vehicle emissions. Not all fuel
dispensers are labeled to indicate
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 reformulated gasoline.
. U.S. government regulations require
ethanol dispensing pumps to be iden-
tified by a small, square, orange and black label with the common abbre-
viation or the appropriate percen-
tage 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
developed this specification to improve
emission system and vehicle performance.
Ask your service station manager if the
gasoline meets the World-Wide Fuel Char-
ter (WWFC) specifications.
Reformulated gasoline
Some fuel suppliers are now producing
reformulated gasolines. These gasolines are
specially designed to reduce vehicle emis-
sions. 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
