ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality and viscosity engine oil to ensure sat-
isfactory engine life and performance. For
additional information, see "Recommended
fluids/lubricants and capacities" (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 Ameri-
can Petroleum Institute (API) certification or
International Lubricant Standardization and
Approval Committee (ILSAC) certification
and SAE viscosity standard. These oils have
the API certification mark on the front of the
container. Oils which do not have the speci-
fied 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.
Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant to select the engine oil viscosity based on
the temperatures at which the vehicle will be
operated before the next oil change. Choos-
ing an oil viscosity other than that recom-
mended could cause serious engine damage.
Selecting the correct oil filter
Your new INFINITI vehicle is equipped with a
high-quality Genuine NISSAN oil filter. When
replacing, use a Genuine NISSAN oil filter or
its equivalent for the reason described in
“Change intervals”.
Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Using engine oil and
filters that are not of the specified quality, or
exceeding recommended oil and filter change
intervals could reduce engine life.

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 withunleaded 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.
• Do not use fuel that contains the octane
booster methylcyclopentadienyl man-
ganese tricarbonyl (MMT). Using fuel
containing MMT may adversely affect
vehicle performance and vehicle emis-
sions. 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 identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage for that
region. For additional information, see “Recom-
mended fluids/lubricants and capacities”
(P. 10-2).
RECOMMENDED ENGINE OIL:
See “Recommended fluids/lubricants and ca-
pacities” (P. 10-2).
COLD TIRE PRESSURE:
For additional information, see “Tire and
Loading Information label” (P. 8-29).
The label is typically located on the driver side
center pillar or on the driver's door. For addi-
tional information, see “Wheels and tires”
(P. 8-27).
RECOMMENDED NEW VEHICLE
BREAK-IN PROCEDURE:
During the first 1,200 miles (2,000 km) of
vehicle use, follow the break-in procedure
recommendations for the future reliability
and economy of your new vehicle. For addi-
tional information, see “Break-in schedule”
(P. 5-131). Failure to follow these recom-
mendations may result in vehicle damage or
shortened engine life.
