1997 NISSAN PATHFINDER Owners Manual

FUEL RECOMMENDATION
All models are designed to operate on
unleaded gasoline with an octane rating of
at least 87 AKI (Anti-Knock Index) number
(Research octane number 91).
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 gasoline
Some fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
NISSAN supports efforts towards cleaner air
and suggest that you use reformulated gaso-
line when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE andmethanol 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 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.
After market fuel additives
NISSAN 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 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 of at
least 87 AKI (Anti-Knock Index) number. How-
ever, you may use unleaded gasoline with an
octane rating as low as 85 AKI (Anti-Knock
Index) number in these high altitude areas
[over 4,000 ft (1,219 m)] such as: Colorado,
Montana, 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 ªspark knockº. (ªSpark
knockº 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 lightspark knock for a short time.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It 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 or SH and Energy Conserving II
categories.
If you cannot find engine oil with the CERTI-
FICATION MARK, an API SG or SH and
Energy Conserving II oil with API Service
Symbol may be used. An oil with a single
designation ªSGº or ªSHº, or in combination
with other categories (for example, ªSG/CCº or
ªSG/CDº) 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. These oils musthowever, 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 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 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 ªRecommended SAE vis-
cosity numberº shows the recommended oil
viscosities for the expected ambient tempera-
tures. Choosing an oil viscosity other than that
recommended could cause serious engine
damage.STI0077

Z01.2.1/R50-DX

Selecting the correct oil filter
Your 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 ªchange intervalsº.
Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Oil and filter other than
the specified quality, or oil and filter change
intervals longer than recommended could re-
duce engine life. Damage to engines caused
by improper maintenance or use of incorrect
oil and filter quality and/or viscosity is not
covered by the new Nissan vehicle warranties.
Your engine was filled with a high quality
engine oil when it was built. You do not have to
change the oil before the first recommended
change interval. Oil and filter change intervals
depend upon how you use your vehicle. Op-
eration under the following conditions may
require more frequent oil and filter changes.
Ð repeated short distance driving at cold out-
side temperatures,
Ð driving in dusty conditions,
Ð extensive idling,Ð towing a trailer.

RECOMMENDED SAE VISCOSITY
NUMBERISAE 5W-30 viscosity oil is preferred for
all ambient temperatures. SAE 10W-30
viscosity oil may be used if the ambient
temperature is above 0ÉF (þ18ÉC).
I75W-90 for transmission and 80W-90 for
differential are preferable if the ambient
temperature is below 104ÉF (40ÉC).

AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONS
The air conditioning system in this NISSAN
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and the lubricant,
Nissan A/C System Oil Type S or the exact
equivalents.Use of any other refrigerants or
lubricants will cause severe damage and you
will need to replace your vehicle's entire air
conditioning system.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle will not harm the earth's
ozone layer. Although this refrigerant does not
affect the earth's atmosphere, certain govern-
mental regulations require the recovery and
recycling of any refrigerant during automotive
air conditioning system service. Your NISSAN
dealer has the trained technicians and equip-
ment needed to recover and recycle your air
conditioning system refrigerant.
Contact your NISSAN dealer when servicing
your air conditioning system.
