ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oilIt 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, SH, or SJ and Energy Conserving I &
II categories.
If you cannot find engine oil with the API
CERTIFICATION MARK, use an API grade
SG/SH, Energy ConservingI&IIorAPIgrade
SJ, Energy Conserving oil. 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. An
ILSAC grade GF-I & GF-II oil can also be used.
Mineral based or synthetic type oils may beused in your NISSAN vehicle. These oils must
however, 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 additivesNISSAN 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 viscosityThe 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 recommended SAE viscos-
ity number shows the recommended oil vis-
cosities for the expected ambient tempera-
tures. Choosing an oil viscosity other than that
recommended could cause serious engine
damage.Selecting the correct oil filterYour new vehicle is equipped with a high-
quality genuine Nissan oil filter. When replac-

However, for long steep grades, do not stay in
1st or 2nd gear when driving above 35 MPH
(56 km/h).
IIf the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan
control to high and setting the temperature
control to the HOT position.
ITrailer towing requires more fuel than nor-
mal circumstances.
IAvoid towing a trailer for the first 500 miles
(800 km).
IHave your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule.
When towing a trailer, change oil in the
transmission more frequently. See the
Maintenance Schedule.UNIFORM TIRE QUALITY
GRADINGDOT (Department of Transportation) Quality
Grades: All passenger car tire must conform to
Federal Safety Requirements in addition to
these grades.Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width. For example:
Treadwear 200 Traction AA Temperature A
TreadwearTreadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified government
test courses. For example, a tire graded 150
would wear one and a half (1-1/2) times as well
on the government course as a tire graded
100. However, relative tire performance de-
pends on actual driving conditions, and may
vary significantly due to variations in driving
habits, service practices and differences in
road characteristics and climate.Traction AA, A, B and CThe traction grades from highest to lowest are
AA, A, B, and C. Those grades represent the
tire's ability to stop on wet pavement as mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests, and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.Temperature A, B and CTemperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sus-
tained high temperature can cause tire mate-
rial to degenerate, reducing tire life. Excessive
temperatures can lead to sudden tire failure.
Grade C corresponds to a performance level
which all passenger car tires must meet under
the Federal Motor Vehicle Safety Standard No.
109. Grades A and B represent higher levels of
performance on laboratory test wheels than
the minimum required by law.Technical and consumer information
