FUEL RECOMMENDATION
Your vehicle is 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 system, and may 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 and
methanol with or without advertising theirpresence. 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 causefuel 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.
Aftermarket 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

![NISSAN SENTRA 2001 B15 / 5.G Owners Manual 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: Col NISSAN SENTRA 2001 B15 / 5.G Owners Manual 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: Col](/manual-img/5/649/w960_649-212.png)
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 the
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 an authorized
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, after-run and/or overheating, which
may cause excessive fuel consumption or
engine damage. If any of the above symp-toms are encountered, have your vehicle
checked at an authorized 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 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 AmericanPetroleum Institute (API) CERTIFICATION
MARK on the front 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&IIorAPI
grade SJ, Energy Conserving oil. An oil with
a single designation SG or SH, or in combi-
nation with other categories (for example,
SG/CC or SG/CD) may also be used if one
with the API CERTIFICATION MARK can-
not be found. An ILSAC grade GF-I & GF-II
oil can also be used.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.
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.

When planning to travel in another coun-
try,you should first find out if the fuel avail-
able is suitable for your vehicle's engine.
Using fuel with too low an octane/cetane
rating may cause engine damage. All gaso-
line vehicles must be operated with un-
leaded gasoline. 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
another country, state, province or dis-
trict and registered, its modifications,
transportation, and registration are the
responsibility of the user. NISSAN is not
responsible for any inconvenience that
may result.

cAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, and if your vehicle is
equipped with an automatic transmission,
first block the wheels and apply the park-
ing brake, and then move the transmis-
sion shift selector lever into the P (Park)
position. If you move the shift selector
lever to the P (Park) position before block-
ing the wheels and applying 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. For
additional information see the ``Mainte-
nance'' section earlier in this manual.
