ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to choose the correct quality
and viscosity oil to ensure satisfactory en-
gine life and performance. Nissan recom-
mends the use of a low friction oil (energy
conserving oil) in order to improve fuel
economy and conserve energy. Oils which
do not have the specified quality label
should not be used as they could cause
engine damage.
Only those engine oils with the AmericanPetroleum Institute (API) CERTIFICATION
MARK on the front of the container should
be used. This type of oil supersedes the
existing API SG or SH and Energy Conserv-
ing II categories.
If you cannot find engine oil with the CER-
TIFICATION MARK, an API SG or SH and
Energy Conserving II oil with API Service
Symbol may be used. An oil with a single
designation SG or SH, or in combination
with other categories (for example, SG/CC
or SG/CD) may also be used if one with the
API CERTIFICATION MARK cannot be
found.Mineral based or synthetic type oils may be
used in your NISSAN vehicle. However,
these oils must meet the API quality and
SAE viscosity ratings specified for your ve-
hicle. Do not mix mineral based and syn-
thetic type oils in the engine at the same
time.
Oil additives
NISSAN 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 important to select the engine oil viscos-
ity based on the temperatures at which the
vehicle will be operated before the next oil
change. The chart ``Recommended SAE
viscosity number'' shows the recommended
oil viscosities for the expected ambient tem-
peratures. Choosing an oil viscosity other
than that recommended could cause seri-
ous engine damage.

Recommended new vehicle
break-in procedure:
During the first 1,000 miles (1,600 km) of
vehicle use, follow the recommendations out-
lined in the ªBREAK-IN SCHEDULE Informa-
tion found in the ªStarting and Drivingº section
of this Owner's Manual. Follow these recom-
mendations for the future reliability and
economy of your new vehicle. Failure to follow
these recommendations may result in vehicle
damage or shortened engine life.
