2019 NISSAN TITAN engine

CAUTION
Be sure to remove any old gasket mate-
rial remaining on the sealing surface of
the engine. Failure to do so could lead to
an oil leak and engine damage.7. Fill the new filter with clean engine oil.
8. Coat the gasket on the new filter with clean engine oil.
9. Screw on the oil filter until a slight resis- tance is felt, then tighten an additional
3/4 turn.
10. Start the engine and check for leakage around the oil filter. Correct as required.
11. Install skid plate in reverse order of re- moval.
12. Turn the engine off and wait more than 10 minutes. Check the oil level. Add en-
gine oil if necessary.
CAUTION
Your vehicle may require more frequent
maintenance if it operates on biodiesel
blends between 6% and 10% (B6 and
B10). To avoid damage to your vehicle,
the oil, oil filter, and fuel filter will need
to be replaced af ter a shorter time in-
terval than if your vehicle was operat-
ing on pure petroleum-based diesel.
For additional information, refer to the
“Maintenance and schedules” section in
the Titan Owner’s Manual.

WARNING
∙ Stay clear from the exhaust outlet andexhaust gases. These can cause burns
or personal injury.
∙ To avoid the risk of personal injury or fire, do not park the vehicle over flam-
mable materials such as dry grass,
waste paper or rags, as hot vehicle
components may ignite them.
CAUTION
To maintain maximum Diesel Particu-
late Filter (DPF) performance, follow
these precautions:
∙ Use ultra low-sulfur fuel.
∙ Use an engine oil specified by NISSAN.For additional information, refer to
“Recommended fluids/lubricants and
capacities” in the “Capacities and
specifications” section of this manual.
If an engine oil not specified by
NISSAN is used, it could cause DPF
malfunction or reduced fuel
efficiency. ∙ Do not modif y the DPF, muffler or ex-
haust pipe. Otherwise it could affect
the DPF performance and cause a
malfunction.
∙ Do not kick or hit the DPF. The DPF has a built-in catalyst system in the muf-
fler. Such an impact could cause DPF
damage.
The DPF reduces the amount of materials
that affect the environment by collecting
particulate matter included in exhaust
gases. Normally, particulate matter accu-
mulated in the DPF is automatically burned
and converted to harmless substances
during driving. However, particulate matter
collected in the DPF cannot be burned un-
der the following conditions: ∙ When vehicle speed remains below 5 mph (8 km/h) for a long period of time.
∙ When the engine is frequently stopped and restarted within 10 minutes.
∙ When the vehicle is frequently used for short journeys of 10 minutes or less.
∙ When the engine is frequently stopped before it has warmed up. In these cases, it becomes difficult to burn
particulate matter that has accumulated
in the DPF. As a result, the DPF warning light
will illuminate/blink and one of the follow-
ing messages will display on the vehicle
information display (in order of severity):
∙ Exhaust Filter Overloaded See Owner’s Manual for Drive Pattern
∙ Exhaust Filter Overloaded Engine Power Reduced See Owner’s Manual
∙ Exhaust Filter Overloaded Immediate Service Required
For additional information, refer to “Meters
and gauges" in the “Instrument panel” sec-
tion of this manual.
CAUTION
∙ If the vehicle continues to be driven with the DPF warning light illumi-
nated and without doing the regen-
eration process, the fail-safe will limit
the engine revolutions and/or torque.
In this case, it is recommended to con-
tact a NISSAN dealer to have the Ser-
vice Regeneration procedure
performed.

AUTOMATIC REGENERATION
Automatic regeneration occurs when the
control module detects the exhaust filter
needs to be cleaned. This is a normal pro-
cess and will not typically require any op-
erator interaction.
If the automatic regeneration is not able to
clean the exhaust filter the vehicle informa-
tion display will display the following mes-
sages in order of severity:∙ Exhaust Filter Overloaded See Owner’s Manual for Drive Pattern
∙ Exhaust Filter Overloaded Engine Power Reduced See Owner’s Manual
∙ Exhaust Filter Overloaded Immediate Service Required
The instructions for these messages in the
“Meters and gauges” section of this manual
will inform the driver to modif y their driving
pattern to enable the automatic regenera-
tion process.

WARNING
∙ Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops the
flame if the engine backfires. If it isn’t
there, and the engine backfires, you
could be burned. Do not drive with the
air cleaner removed, and be careful
when working on the engine with the
air cleaner removed.
∙ Never pour fuel into the air intake sys- tem or attempt to start the engine
with the air cleaner removed. Doing so
could result in serious injury.
∙ Do not use starting fluids with this en- gine. The use of starting fluid could
cause an explosion, fire, personal in-
jury, system or engine damage.
CAUTION
∙ Operating the engine with the aircleaner removed can cause damage
to the turbocharger and major engine
damage.
∙ Never pour fuel into the intake or at- tempt to start the engine with the air
cleaner removed. Doing so could re-
sult in engine damage.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry
of airborne dust and pollen particles and
reduces some objectionable outside
odors. The filter is located behind the glove
box. For additional information on change
intervals, refer to “Gasoline standard main-
tenance" or "Diesel standard mainte-
nance" in the "Maintenance and sched-
ules" section of the Titan Owner’s Manual.

FUEL RECOMMENDATION
Diesel engine
Commercially available diesel fuel is ad-
justed seasonally for cold temperatures.
NISSAN recommends the use of diesel fuel
that has been seasonally adjusted for tem-
peratures below 32°F (0°C)
Diesel fuel of above 42 cetane minimum
above 32°F (0°C); 45 cetane minimum be-
low 32°F (0°C) and with less than 15 ppm of
sulfur must be used.
A cetane number below 42 can cause poor
starting, excessive white smoke, and poor
idling. A cetane number above 55 can in-
crease smoke at peak torque conditions.
If two types of diesel fuel are available, use
summer or winter fuel properly according
to the following temperature conditions.∙ Above 32°F (0°C) . . . Summer type diesel
fuel.
∙ Below 32°F (0°C) . . . Winter type diesel fuel.
If you are in any doubt, it is recommended
that you consult a NISSAN dealer.
CAUTION
∙ Do not use home heating oil, petro- leum, biodiesel (more than 10%) or
other alternate fuels in your diesel en-
gine. The use of those can cause en-
gine damage.
∙ Do not use summer fuel at tempera- tures below 20°F (- 7°C). The cold tem-
peratures will cause wax to form in
the fuel. As a result, it may prevent the
engine from running smoothly.
B10 fuel
B10 fuel is a mixture of approximately 10%
biodiesel and 90% petroleum diesel. Your
vehicle was designed to run on blends of
biodiesel up to B10 (B1-B10). Operating your
vehicle on higher blends is not recom-
mended. Your vehicle’s engine, exhaust
catalyst filter and particulate filter, and fuel
system components may be damaged if
any of these blends are used.
U.S. government regulations require that
biodiesel blends between B6 and B10 are
identified at fuel dispensing pumps by a
label with the common abbreviation or the
appropriate percentage for that region. B6
--B10 blends must meet prescribed quality
standards specified by ASTM D7467.
B10 fuel storage
Biodiesel degrades more quickly than pure
petroleum-based diesel. When storing a
vehicle that runs on a biodiesel blend, it is
important to keep the following in mind:
∙ If storing a vehicle for longer than one month, empty the fuel tank of biodiesel.
∙ To prepare a vehicle to run af ter pro- longed storage, fill the fuel tank with a
pure petroleum-based diesel fuel and
run your vehicle for at least half an hour.
∙ Fuel system seals, plastics and steel parts can be damaged by degraded or
oxidized biodiesel.
During cold weather, biodiesel fuel may
need to be stored in a heated storage tank
in order to prevent it from gelling or solidi-
f ying.
Diesel Exhaust Fluid (DEF)
DEF is a solution composed of urea and
de-ionized water. In diesel vehicles, it is
used as part of the exhaust system to
break down harmful NOx emissions into
nitrogen and water. It is important to keep
your vehicle’s DEF tank filled properly.

ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
NOTE:
The factory fill oil may include a red dye
that that is added for manufacturing
quality processes. The dye makes the oil
appear to be red. This is normal. The red
dye will be flushed from the engine af ter
approximately 4-5 oil changes.It is essential to choose the correct grade,
quality and viscosity engine oil to ensure
satisfactory engine life and performance.
For additional information, refer to “Recom-
mended fluids/lubricants and capacities”
in this section. NISSAN recommends the
use of an energy conserving oil in order to
improve fuel economy.Select only engine oils that meet the Cum-
mins® Engineering Standard (CES) classifi-
cation (CES 20081) and American Petro-
leum Institute (API) certification (API CJ-4,
Low Ash Oil) and SAE viscosity standard
(10W-30 or 5W-40). These oils have the API
certification mark and CES 20081 on the
container. Oils which do not have the
specified information on the 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.LTI2207
