1997 NISSAN SENTRA service

FUEL RECOMMENDATION
All models are designed to operate on
unleaded gasoline with an octane rating
of at least 87 AKI (Anti-Knock Index)
(Research octane number 91).
CAUTION
cUsing a fuel other than that specified
could adversely affect the emission
control devices and systems, and
could also affect the warranty
coverage.
cUnder no circumstances should a
leaded gasoline be used, since this
will damage the three way catalyst.
Reformulated Gasoline
Some fuel suppliers are now producing re-
formulated gasolines. These gasolines are
specially designed to reduce vehicle emis-
sions. NISSAN supports efforts towards
cleaner air and suggests that you use refor-
mulated gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE andmethanol with or without advertising their
presence. 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 service 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.
cThe fuel should be unleaded and
have an octane rating no lower than
that recommended for unleaded
gasoline.
cIf an oxygenate-blend other than a
methanol blend is used, it should
contain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
cIf 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
performance problems. At this time,
sufficient data is not available to en-
sure that all methanol blends are suit-
able for use in NISSAN vehicles.
If any driveability problems such as engine
stalling and hard hot-starting are experi-
enced after 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
refueling. Gasoline containing oxygen-
ates can cause paint damage.
After Market Fuel Additives
NISSAN does not recommend the use of
any fuel additives (i.e., fuel injector cleaners,
octane boosters, intake valve deposit re-
movers, etc.) which are sold commercially.
Many of these additives intended for gum,
varnish or deposit removal may contain ac-
tive solvents or similar ingredients that can
be harmful to the fuel system and engine.
Octane rating tips
In most parts of North America, you should
use unleaded gasoline with an octane rating
9-3
ZX

of at least 87 AKI (Anti-Knock Index). How-
ever, you may use unleaded gasoline with
an octane rating as low as 85 AKI (Anti-
Knock Index) in high altitude areas (over
4,000 ft [1,219 m]) such as: Colorado, Mon-
tana, New Mexico, Utah, Wyoming, north-
eastern Nevada, southern 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
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, have your dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.
Incorrect ignition timing results in knocking,
after-run and/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 ve-hicle 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
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
RECOMMENDATION
Selecting the correct oil
It is essential to choose the correct quality
and viscosity oil to ensure satisfactory en-
gine life and performance. Nissan recom-
mends 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 AmericanPetroleum 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 CER-
TIFICATION MARK, an API SG or SH and
Energy Conserving II oil with 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. However,
these oils must 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 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 important to select the engine oil viscos-
ity 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 tem-
peratures. Choosing an oil viscosity other
than that recommended could cause seri-
ous engine damage.

RECOMMENDED SAE
VISCOSITY NUMBER
cSAE 5W-30 viscosity oil is preferred
for all temperatures. SAE 10W-30 vis-
cosity oil may be used if the ambient
temperature is above 0ÉF (-18ÉC).c80W-90 is preferable for outside tem-
peratures below 104ÉF (40ÉC).
AIR CONDITIONER SYSTEM RE-
FRIGERANT AND LUBRICANT
RECOMMENDATIONS
The air conditioner in your NISSAN ve-
hicle must be charged with the refriger-
ant HFC-134a (R-134a) and the lubricant,
NISSAN A/C system oil Type R or the
exact equivalents.
CAUTION
Use of any other refrigerant or lubricant
will cause severe damage and you will
need to replace your vehicle's entire air
conditioner system.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle does not harm the earth's
ozone layer. Although this refrigerant does
not affect the earth's atmosphere, certain
governmental regulations require the recov-
ery and recycling of any refrigerant during
automotive air conditioner system service.
Your NISSAN dealer has the trained tech-
nicians and equipment needed to recover
and recycle your air conditioner system
refrigerant.
Contact your NISSAN dealer when servic-
ing your air conditioner system.

the parking brake, transmission damage
could occur.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
cIf the engine temperature 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 win-
dows, switching the fan control to high
and setting the temperature control to
the HOT position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for your vehicle's
first 500 miles (800 km).
cHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
cWhen making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.cCrosswinds and rough roads adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being
passed by larger vehicles, be prepared
for possible changes in crosswinds that
could affect vehicle handling. If swaying
does occur, firmly grip the steering
wheel, steer straight ahead, and imme-
diately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
cTo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
cAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change the oil in
the transmission more frequently.
See the Maintenance Schedule.DOT Quality Grades: All passenger car tires
must conform to Federal Safety Require-
ments in addition to these grades.
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment 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 depends on actual
driving conditions, and may vary signifi-
cantly from the norm due to variations in
driving habits, service practices and differ-
ences in road characteristics and climate.
Traction A, B and C
Traction grades are A (the highest), B and C.
They represent a tire's ability to stop on wet
pavement as measured under controlled con-
ditions, on specified government test sur-
faces of asphalt and concrete. A tire marked
with a C may have poor traction performance.
WARNING
The traction grade assigned to your
vehicle tires is based on straight line
