may cause excessive fuel consumption or
damage to the engine. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended you visit an
INFINITI retailer for servicing.
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.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see “Capacities and recommended fluids/
lubricants” (P.10-2). INFINITI recommends
the use of an energy conserving oil in order
to improve fuel economy.
Select only engine oils that meet the Amer-
ican Petroleum Institute (API) certificationor International Lubricant Standardization
and Approval Committee (ILSAC) certifica-
tion and SAE viscosity standard. These oils
have the API certification 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
additives. 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.

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. 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 containing 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 new vehicle limited war-
ranty.
. 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.
ENGINE OIL RECOMMENDA-
TION:
See “Capacities and recommended fluids/
lubricants” (P.10-2) for engine oil and oil
filter recommendation.
COLD TIRE PRESSURES:
The label is typically located on the driver
side center pillar or on the driver’s door. For
additional information, see “Wheels and
tires” (P.8-25).
NEW VEHICLE BREAK-IN PRO-
CEDURES RECOMMENDATION:
During the first 1,200 miles (2,000 km) of
vehicle use, follow the recommendations
outlined in the “Break-in schedule” (P.5-
118) of this Owner’s Manual. Follow these
recommendations for the future reliability
and economy of your new vehicle.
