ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to choose the correct quality, and
viscosity oil to ensure satisfactory engine life
and performance. Nissan recommends the
use of a low friction oil (energy conserving oil)
in order to improve fuel economy and con-
serve 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 American Pe-
troleum Institute (API) CERTIFICATIONMARK on the front of the container should be
used. This type of oil supersedes the existing
API SG or SH and Energy Conserving II
categories.
If you cannot find engine oil with the CERTI-
FICATION MARK, an API SG or SH and
Energy Conserving II oil with API Service
Symbol may be used. An oil with a single
designation ªSGº or ªSHº, or in combination
with other categories (for example, ªSG/CCº or
ªSG/CDº) 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. These oils musthowever, meet the API quality and SAE vis-
cosity ratings specified for your vehicle. Do not
mix mineral based and synthetic 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 impor-
tant that the engine oil viscosity be selected
based on the temperatures at which the ve-
hicle will be operated before the next oil
change. The chart ªRecommended SAE vis-
cosity numberº shows the recommended oil
viscosities for the expected ambient tempera-
tures. Choosing an oil viscosity other than that
recommended could cause serious engine
damage.STI0077
