Mineral based or synthetic type oils may be used in your NISSAN vehicle. These oils must however, meet the API quality and SAE viscosity ratings specified for your vehicle. Do not mix mineral based and synthetic type oils in the engine. 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. ATI0507 ENGINE OIL AND OIL FILTER RECOMMENDATION Selecting the correct oil It is essential to chose engine oil with the correct quality and viscosity 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 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 American Petroleum 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 Conserving II categories. If you cannot find engine oil with the CERTIFICATION MARK, an API SG or SH, an Energy Conserving II oil with the 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. 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 that the engine oil viscosity be selected 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 temperatures. Choosing an oil viscosity other than that recommended could cause serious engine damage. 10-6 Technical and consumer information

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to chose engine oil with the
correct quality and viscosity to ensure sat-
isfactory engine life and performance. NIS-
SAN recommends the use of a low friction
oil (energy conserving oil) in order to im-
prove 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 American
Petroleum 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 CERTI-
FICATION MARK, an API SG or SH, an
Energy Conserving II oil with the 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. These oils
must however, 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.
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 that the engine oil viscosity be
selected
based
on
the
temperatures
at
which the vehicle will be operated before
the next oil change. The chart ‘‘Recom-
mended SAE viscosity number’’ shows the
recommended
oil
viscosities
for
the
ex-
pected ambient temperatures. Choosing an
oil viscosity other than that recommended
could cause serious engine damage.
