CHANGING ENGINE OIL1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn the engine off and wait more than 10
minutes.
4. Place a large drain pan under the drain
plug.
5. Remove the oil filler cap.6. Remove the drain plug with a wrench and
completely drain the oil.
If oil filter is to be changed, remove and
replace it at this time. See later in ªEngine
oilº for changing engine oil filter.
CAUTION
Be careful not to burn yourself, as the
engine oil is hot.
IWaste oil must be disposed of properly.
ICheck your local regulations.
7. Clean and re-install the drain plug with a
new washer. Securely tighten the drain plug
with a wrench.
Drain plug tightening torque:
22 to 29 ft-lb
(29 to 39 N×m)
Do not use excessive force.
8. Refill engine with recommended oil and
install the cap securely.
See ªCapacities and recommended
fuel/lubricantsº in the ª9. Technical and
consumer informationº section for drain andrefill capacity. The drain and refill capacity
depends on the oil temperature and drain
time. Use these specifications for reference
only. Always use the dipstick to determine
the proper amount of oil in the engine.
9. Start the engine.
Check for leakage around the drain plug.
Correct as required.
10.Turn the engine off and wait more than 10
minutes. Check the oil level with the dip-
stick. Add engine oil if necessary.
11.Dispose of waste oil properly.
WARNING
IProlonged and repeated contact with
used engine oil may cause skin can-
cer.

REPLACING SPARK PLUGS
Platinum-tipped spark plugsIt is not necessary to replace the platinum-
tipped spark plugs as frequently as the con-
ventional type spark plugs since they will last
much longer. Follow the maintenance sched-
ule but, do not reuse them by cleaning or
regapping.
If replacement is required, see your NISSAN
dealer for servicing.
Always replace with recommended
platinum-tipped spark plugs.The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See the separate Service and
Maintenance Guide. When replacing the filter,
wipe the inside of the air cleaner housing and
the cover with a damp cloth.
WARNING
IOperating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleanernot only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed and be care-
ful when working on the engine with
the air cleaner removed.
INever pour fuel into the throttle body
or attempt to start the engine with the
air cleaner removed. Doing so could
result in serious injury.

FUEL RECOMMENDATIONUse unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
For improved vehicle performance,
NISSAN recommends the use of unleaded
premium gasoline with an octane rating of
at least 91 AKI number (Research octane
number 96).
CAUTION
Using a fuel other than that specified
could adversely affect the emission con-
trol devices and systems, and could
also affect the warranty coverage.
Under no circumstances should a
leaded gasoline be used, since this will
damage the three-way catalyst.Reformulated gasolineSome fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
NISSAN supports efforts towards cleaner airand suggests that you use reformulated gaso-
line when available.
Gasoline containing oxygenatesSome fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and
methanol with or without advertising their pres-
ence. NISSAN does not recommend the use of
fuels of which the oxygenate content and the
fuel compatibility for your NISSAN cannot be
readily determined. If in doubt, ask your ser-
vice station manager.
If you use oxygenate-blend gasoline, please
take the following precautions as the usage of
such fuels may cause vehicle performance
problems and/or fuel system damage.
IThe fuel should be unleaded and have
an octane rating no lower than that rec-
ommended for unleaded gasoline.
IIf an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
IIf a methanol blend is used, it should
contain no more than 5% methanol (me-
thyl alcohol, wood alcohol). It should
also contain a suitable amount of appro-
priate cosolvents and corrosion inhibi-tors. If not properly formulated with ap-
propriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or ve-
hicle performance problems. At this
time, sufficient data is not available to
ensure that all methanol blends are suit-
able for use in NISSAN vehicles.
If any undesirable driveability problems such
as engine stalling and hard hot starting are
experienced after using oxygenate-blend fu-
els, immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
Aftermarket fuel additivesNISSAN does not recommend the use of any
fuel additives (i.e. fuel injector cleaner, octane
booster, intake valve deposit removers, etc.)
which are sold commercially. Many of these
additives intended for gum, varnish or deposit
removal may contain active solvent or similar
ingredients that can be harmful to the fuel
system and engine.Octane rating tipsIn most parts of North America, you should use

unleaded gasoline with an octane rating of at
least 87 or 91 AKI (Anti-Knock Index) number.
However, you may use unleaded gasoline with
an octane rating as low as 85 AKI number in
these high altitude areas [over 4,000 ft (1,219
m)] such as: Colorado, Montana, New Mexico,
Utah, Wyoming, northeastern Nevada, south-
ern Idaho, western South Dakota, western
Nebraska, and that part of Texas which is
directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may
cause excessive fuel consumption or damage
to the engine. If any of the above symptoms
are encountered, have your vehicle checked at
a NISSAN dealer or other competent service
facility.However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.9-4

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) certification mark on thefront of the container should be used. This type
of oil supersedes the existing API SG, SH, or
SJ and Energy ConservingI&IIcategories.
If you cannot find engine oil with the API
certification mark, use an API grade SG/SH,
Energy ConservingI&IIorAPIgrade SJ or
SL, 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 & GF-III oil can also be used.
NISSAN recommends mineral based oils.
These oils must however, meet the API qualityand SAE viscosity ratings specified for your
vehicle.
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 recommended SAE viscosity
number chart shows the recommended oil
viscosities 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-
ing, use the genuine oil filter or its equivalent
for the reason described in change intervals.

When planning to travel in another country,
you should first find out if the fuel available is
suitable for your vehicle's engine.
Using fuel with too low an octane rating may
cause engine damage. All gasoline vehicles
must be operated with unleaded engine gaso-
line. Therefore, avoid taking your vehicle to
areas where appropriate fuel is not available.
When transferring the registration of your
vehicle to another country, state, province
or district,it may be necessary to modify the
vehicle to meet local laws and regulations.
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications may
differ.
When any vehicle is to be taken into an-
other country, state, province or district
and registered, its modifications, transpor-
tation, and registration are the responsibil-
ity of the user. NISSAN is not responsible
for any inconvenience that may result.
