1998 NISSAN MAXIMA engine oil

If jump starting is necessary, see ªJump start-
ingº the ª6. In case of emergencyº section. If
the engine does not start by jump starting, the
battery may have to be replaced. Contact your
NISSAN dealer.
Be sure the ignition key is OFF. The
engine could rotate unexpectedly.1. Visually inspect each belt for signs of un-
usual wear, cuts, fraying, oil adhesion or
looseness. If the belt is in poor condition or
loose, have it replaced or adjusted by your
NISSAN dealer.
2. Have the belts checked regularly for condi-
tion and tension in accordance with the
maintenance schedule in this manual.

Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.Be sure to use the correct wrench to
remove the plugs. An incorrect wrench
can cause damage.
REPLACING SPARK PLUGS1. Remove the rocker cover ornament using a
suitable hexagon wrench. (Front side)
2. Disconnect the electrical connectors.
3. Loosen the ignition coil fixing bolts. And
remove the ignition coil to give access to
the spark plugs.
4. Remove the spark plugs with a spark plug
wrench.
The plug wrench has a rubber seal that
holds the spark plug so that it will not fall
when it is pulled out. Make sure that eachspark plug is snugly fitted into the plug
wrench.
5. Fit the new plugs, one at a time, into the
spark plug wrench and install them. Turn
each plug in several full turns by hand, then
tighten with a spark plug wrench to the
correct torque. Do not overtighten.

vehicle to one side when applied.
Brake pedal and booster*:Check the pedal
for smooth operation and make sure it has the
proper distance under it when depressed fully.
Check the brake booster function. Be sure tokeep floor mats away from the pedal.
Parking brake*:Check that the lever has the
proper travel and make sure that the vehicle is
held securely on a fairly steep hill when only
the parking brake is applied.
Automatic transaxle P (Park) position
mechanism:Check that the brake pedal must
be depressed for the selector lever to be
moved from the P (Park) position. On a fairly
steep hill check that the vehicle is held se-
curely with the selector lever in the P (Park)
position without applying any brakes.
Under the hood and the vehicleThe maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Windshield washer fluid*:Check that there
is adequate fluid in the tank.
Engine coolant level*:Check the coolant
level when the engine is cold.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure
the hoses have no cracks, deformation, dete-
rioration or loose connections.Brake and clutch fluid levels*:Make sure
that the brake and clutch fluid levels are be-
tween the MAX and MIN lines on the reservoir.

ITEMSAdditional information on the following
items with ª*º is found in the ª8. Do-it-
yourselfº section.Emission control system
maintenanceDrive belts*:Check drive belts for wear, fray-
ing or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filter:Under normal driving con-
ditions, the air cleaner filter should be replaced
in accordance with the maintenance schedule.
However, driving the vehicle in dusty areas
may cause more rapid clogging of the element.
Consequently, the element may have to be
replaced more frequently.
EVAP vapor lines:Check EVAP vapor lines
and connections for failure or looseness. If
leaks are found, replace them.
Fuel lines:Check the fuel hoses, piping and
connections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.Fuel filter:If the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are either
extremely low or extremely high, the filter
might become clogged. In such an event,
replace the filter immediately.
Engine coolant*:Drain and flush the cooling
system.
Engine oil & oil filter*:Under normal driving
conditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe driv-
ing conditions, they may have to be replaced
more frequently.
Spark plugs*:Replace with new plugs having
the correct heat range.
Intake & exhaust valve clearance:Check the
valve clearance if valve noise increases.
Chassis and body maintenanceBrake lines & cables:Check the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and park-
ing brake cables for proper attachment, leaks,
cracks, chafing, abrasion, deterioration, etc.Brake pads & discs:Check these and the
other neighboring brake components for wear,
deterioration and leaks. Under severe driving
conditions, they may have to be inspected
more frequently.
Manual & automatic transaxle fluid*:Check
the fluid level and visually inspect for signs of
leakage.
Under severe driving conditions, the oil should
be replaced at the specified interval.
Steering gear & linkage, axle & suspension
parts, and drive shaft boots:Check for dam-
age, looseness and leakage of oil or grease.
Under severe driving conditions, more fre-
quent inspection should be performed.
Exhaust system:Visually check the exhaust
pipes, muffler, and hangers for proper attach-
ment, leaks, cracks, chafing, abrasion, dete-
rioration, etc. Under severe driving conditions,
inspection should be performed more fre-
quently.

FUEL RECOMMENDATIONUnleaded premium gasoline with an octane
rating of at least 91 AKI (Anti-Knock Index)
number (Research octane number 96)
If unleaded premium gasoline is not avail-
able, unleaded regular gasoline with an
octane rating of at least 87 AKI (Research
octane number 91) can be used.
However, for maximum vehicle perfor-
mance, the use of unleaded premium gaso-
line is recommended.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.

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.
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 or SH
and Energy Conserving II categories.
If you cannot find engine oil with the certifica-
tion 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. These oils must
however, meet the API quality and SAE vis-
