NOTE:
(1) Af ter 30,000 miles (48,000 km) or 48 months, inspect every 7,500 miles (12,000 km) or 12 months. Replace the drive belts if
found damaged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Periodic maintenance is not required.
(4) First replacement interval is 105,000 miles (168,000 km) or 84 months. Af ter first replacement, replace every 75,000 miles
(120,000 km) or 60 months.
(5) Use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with proper mixture ratio of 50% antifreeze and 50%
demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water may reduce the life expectancy
of the factory fill coolant.
(6) If the oil replacement indicator is displayed, change the engine oil and filter within two weeks or less than 500 miles (800 km)
(7) Replace spark plug when the plug gap exceeds 0.049 in (1.25 mm) even if within specified periodic replacement mileage.
(8) Periodic maintenance is not required. However, if valve noise increased, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and
intervals are required.

LUBRICANTS AND CAPACITIES
10-2Technical and consumer information

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.∙ The fuel should be unleaded and have
an octane rating no lower than that
recommended for unleaded gasoline.
∙ If an oxygenate-blend other than
methanol blend is used, it should
contain no more than 15% oxygenate.
∙ If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable
amount of appropriate cosolvents
and corrosion inhibitors. If not prop-
erly formulated with appropriate co-
solvents and corrosion inhibitors,
such methanol blends may cause fuel
system damage and/or vehicle per-
formance problems. At this time, suf-
ficient data is not available to ensure
that all methanol blends are suitable
for use in NISSAN vehicles.
If any driveability problems such as engine
stalling and difficult hot-starting are expe-
rienced af ter using oxygenate-blend fuels, immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during re-
fueling. Gasoline containing oxygenates
can cause paint damage.
E–15 fuel
E-15 fuel is a mixture of approximately 15%
fuel ethanol and 85% unleaded gasoline.
E-15 can only be used in vehicles designed
to run on E-15 fuel. U.S. government regula-
tions require fuel ethanol dispensing
pumps to be identified with small, square,
orange and black label with the common
abbreviation or the appropriate percent-
age for that region.
E–85 fuel
E-85 fuel is a mixture of approximately 85%
fuel ethanol and 15% unleaded gasoline.
E-85 can only be used in a Flexible Fuel
Vehicle (FFV). Do not use E-85 in your ve-
hicle. U.S. government regulations require
fuel ethanol dispensing pumps to be iden-
tified by a small, square, orange and black
label with the common abbreviation or the
appropriate percentage for that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting ad-
ditive. NISSAN does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding the emissions control system. Note
that while some fuel pumps label MMT
content, not all do, so you may have to
consult your gasoline retailer for more de-
tails.
Af termarket fuel additives
NISSAN does not recommend the use of
any af termarket fuel additives (for ex-
ample, 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 sol-
vents or similar ingredients that can be
harmful to the fuel system and engine.
Technical and consumer information10-5

Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can
cause persistent, heavy “spark knock.”
(“Spark knock” is a metallic rapping
noise.) If severe, 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, it is recom-
mended that you have a NISSAN dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.
Incorrect ignition timing may result in
spark knock, af ter-run and/or overheating,
which may cause excessive fuel consump-
tion or engine damage. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not
a cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality and viscosity engine oil to ensure
satisfactory engine life and performance.
For additional information, refer to “Recom-
mended fluids/lubricants and capacities”
in this section. NISSAN recommends the
use of an energy conserving oil in order to
improve fuel economy.
Select only engine oils that meet the Ameri-
can Petroleum Institute (API) certification orInternational Lubricant Standardization and
Approval Committee (ILSAC) certification
and SAE viscosity standard. These oils have
the API certification mark on the front of the
container. Oils which do not have the speci-
fied quality label should not be used as they
could cause engine damage.
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.
