2021 NISSAN TITAN engine

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 con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
• E-15 fuel contains more than 10% oxy-
genate. E-15 fuel will adversely affect
the emission control devices and sys-
tems of the vehicle and should not be
used. Damage caused by such fuel is
not covered by the NISSAN New Vehicle
Limited Warranty. •
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 corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not avail-
able 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. Do not use E-15 in your
vehicle. U.S. government regulations re-
quire fuel ethanol dispensing pumps to be
identified with small, square, orange and black label with the common abbreviation
or the appropriate percentage for that re-
gion.
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.
Technical and consumer information10-5

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.
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, see “Recom-
mended fluids/lubricants and capacities”
(P. 10-2). NISSAN recommends the use of an
energy conserving oil in order to improve
fuel economy.Select only engine oils that meet the
American Petroleum Institute (API) certifi-
cation or International Lubricant Standard-
ization 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 specified 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.
Oil viscosity
The engine oil viscosity or thickness
changes with temperature. Because of
this, it is important to select the engine oil
viscosity based on the temperatures at
which the vehicle will be operated before
the next oil change. Choosing an oil viscos-
ity other than that recommended could
cause serious engine damage.
Selecting the correct oil filter
Your new NISSAN vehicle is equipped with a
high-quality Genuine NISSAN oil filter. When
replacing, use a Genuine NISSAN oil filter or
its equivalent for the reason described in
“Change intervals.”
LTI2051
Technical and consumer information10-7

Change intervals
The oil and oil filter change intervals for
your engine are based on the use of the
specified quality oils and filters. Using en-
gine oil and filters that are not of the speci-
fied quality, or exceeding recommended oil
and filter change intervals could reduce
engine life. Damage to the engine caused
by improper maintenance or use of incor-
rect oil and filter quality and/or viscosity is
not covered by the NISSAN New Vehicle
Limited Warranty.
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 recom-
mended change interval. Oil and filter
change intervals depend upon how you
use your vehicle.
Operation under the following conditions
may require more frequent oil and filter
changes:
• repeated short distance driving at coldoutside temperatures
• driving in dusty conditions
• extensive idling
• towing a trailer
• stop and go commuting For additional information, see the “Mainte-
nance and schedules” section of this
manual.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your
NISSAN vehicle must be charged with the
refrigerant HFO-1234yf (R-1234yf ) and
NISSAN A/C system oil Type PAG
(VC100yf oil) or the exact equivalents.
CAUTION
The use of any other refrigerant or oil
may cause severe damage to the air
conditioning system and may require
the replacement of all air conditioner
system components. The refrigerant HFO-1234yf (R-1234yf ) in
your NISSAN vehicle does not harm the
earth's ozone layer. Although this refriger-
ant does not affect the earth's atmo-
sphere, certain government regulations re-
quire the recovery and recycling of any
refrigerant during automotive air condi-
tioner system service. Air conditioner sys-
tem should only be service by trained and
certified technicians to ensure proper and
safe operation (SAE J2845). A NISSAN dealer
has the trained technicians and equip-
ment needed to recover and recycle your
air conditioner system refrigerant. Only
new and SAE J2842 certified evaporator(s)
shall be used as replacement parts.
A damaged or leaking air conditioning
evaporator shall never be repaired or re-
placed with one removed from a used or
salvaged vehicle. To replace a damaged or
leaking evaporator, use only new and SAE
J2842 certified evaporator(s). It is recom-
mended that you visit a NISSAN dealer when
servicing your air conditioner system.

When planning to drive your NISSAN ve-
hicle in another country,you should first
find out if the fuel available is suitable for
your vehicle's engine.
Using fuel with an octane rating that is too
low 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 modif y 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, prov-
ince or district; therefore, vehicle specifica-
tions may differ.
When any vehicle is to be taken into an-
other country, state, province or district
and registered, its modifications, trans-
portation and registration are the re-
sponsibility of the user. NISSAN is not re-
sponsible for any inconvenience that
may result.

The total cargo load should not exceed the
truck's cargo weight rating and the camp-
er's center of gravity should fall within the
truck's recommended center of gravity
zone when installed.
WARNING
Overloading or improper loading can
adversely affect vehicle handling, brak-
ing and performance and may lead to
accidents.
VEHICLE LOAD WEIGHT CAPACITY
The vehicle payload weight capacity
shown on the Tire and Loading Information
label indicates the maximum total weight
of passengers, optional equipment (air
conditioning, trailer hitch, etc.) and cargo
that your vehicle is designed to carry.
For additional information, see “Tire and
Loading Information label” (P. 8-37).
Before driving a loaded vehicle, confirm
that you do not exceed the GVWR or the
GAWR for your vehicle. For additional infor-
mation, see “Vehicle loading information”
(P. 10-22).
Also check tires for proper inflation pres-
sures. For additional information, see “Tire
and Loading Information label” (P. 8-37).
MEASUREMENT OF WEIGHTS
Secure loose items to prevent
weight shif ts that could affect the
balance of your vehicle. When the
truck camper is loaded, drive to a
scale and weigh on the front and on
the rear wheels separately to deter-
mine axle loads. Individual axle loads
should not exceed either of the
gross axle weight ratings (GAWR).
The total of the axle loads should not
exceed the gross vehicle weight rat-
ing (GVWR). These ratings are given
on the vehicle certification label that
is located on the lef t side of the ve-
hicle, normally the dash, hinge pillar,
door latch post, or door edge next to
the driver. If weight ratings are ex-
ceeded, move or remove items to
bring all weights below the ratings.
WARNING
Overloading or improper loading of a
trailer and its cargo can adversely af-
fect vehicle handling, braking and per-
formance and may lead to accidents.
CAUTION
• Do not tow a trailer or haul a heavy
load for the first 500 miles (805 km).
Your engine, axle or other parts could
be damaged.
• For the first 500 miles (805 km) that
you tow a trailer, do not drive over 50
mph (80 km/h) and do not make
starts at full throttle. This helps the
engine and other parts of your ve-
hicle wear in at the heavier load.
Your new vehicle was designed to be used
primarily to carry passengers and cargo.
Remember that towing a trailer places ad-
ditional loads on your vehicle's engine,
drive train, steering, braking and other sys-
tems.
