2019 NISSAN TITAN oil

FUEL RECOMMENDATION:
Gas engine only
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
CAUTION
∙ Using a fuel other than that specifiedcould adversely affect the emission
control system, and may also affect
the warranty coverage.
∙ Under no circumstances should a leaded gasoline be used, because this
will damage the three-way catalyst.
∙ Do not use E-15 or E-85 fuel in your vehicle. Your vehicle is not designed to
run on E-15 or E-85 fuel. Using E-15 or
E-85 fuel in a vehicle not specifically
designed for E-15 or E-85 fuel can ad-
versely affect the emission control
devices and systems of the vehicle.
Damage caused by such fuel is not
covered by the NISSAN New Vehicle
Limited Warranty. ∙ Do not use fuel that contains the oc-
tane booster methylcyclopentadienyl
manganese tricarbonyl (MMT). Using
fuel containing MMT may adversely
affect vehicle performance and ve-
hicle emissions. Not all fuel dispens-
ers are labeled to indicate MMT con-
tent, so you may have to consult your
gasoline retailer for more details.
Note that Federal and California laws
prohibit the use of MMT in reformu-
lated gasoline.
∙ U.S. government regulations require ethanol dispensing pumps to be iden-
tified by a small, square, orange and
black label with the common abbre-
viation or the appropriate percentage
for that region.
For additional information, refer to “Recom-
mended fluids/lubricants and capacities”
in the “Technical and consumer informa-
tion” section of this manual.
Diesel engine only
For additional information, refer to “Fuel
recommendation” in the Titan Diesel Own-
er’s Manual.
ENGINE OIL RECOMMENDATION:
Gas engine only ∙ Genuine “Nissan Motor Oil 0W-20” (or equivalent).
For additional information, refer to “Engine
oil and oil filter recommendations” in the
“Technical and consumer information” sec-
tion of this manual.
Diesel engine only
For additional information, refer to “Engine
oil recommendation” in the Titan Diesel
Owner’s Manual.
COLD TIRE PRESSURE:
Refer to the Tire and Loading Information
label.
The label is typically located on the driver
side center pillar or on the driver’s door. For
additional information, refer to “Wheels and
tires” in the “Do-it-yourself ” section of this
manual.
GAS STATION INFORMATION

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.
FUEL FILTER REPLACEMENT (stage
1)
NOTE:∙ It is possible the “Low Fuel Pressure:
See Owner’s Manual” message will
display on the vehicle information
display af ter fuel filter replacement
due to air being introduced into the
fuel system. ∙
If the “Low Fuel Pressure: See Owner’s
Manual” message is displayed on the
vehicle information display with the
engine running, complete a full key
cycle (turn the vehicle off and wait
2 minutes) and restart the vehicle. If
the message is still displayed or the
Malfunction Indicator Light is illumi-
nated af ter a full key cycle , it is rec-
ommended that you visit a NISSAN
dealer for service.
WARNING
∙ The fuel system (fuel pump, high pres- sure fuel lines, fuel rail, injectors) con-
tain very high pressure fuel. To avoid
the risk of personal injury or fire;
– Do not loosen any fittings while the engine is running.
– Wait at least 10 minutes af ter shut- ting down the engine before loos-
ening any fittings in the high-
pressure fuel system to allow
pressure to decrease to a lower
level.
– Wear appropriate eye protection and protective equipment as high-
pressure fuel spray can penetrate
the skin.

FUEL FILTER (CUMMINS 5.0L)

Preventive maintenance is the easiest and
least expensive type of maintenance. Keep
records of regularly scheduled mainte-
nance and follow the maintenance sched-
ule recommendations outlined in the Titan
Owner’s Manual.
Use the correct fuel, lubricating oil, and
coolant in your engine. Blending engine oil
with fuel is prohibited for engines with an
af tertreatment system. For additional in-
formation, refer to the “Capacities and
specifications” section of this manual.
A NISSAN dealership knows your vehicle.
When you require any service or have any
questions, they will be glad to assist you
with the extensive resources available to
them.
DIESEL ENGINE OPERATION
The operation of the diesel engine in your
new vehicle varies from the operation of
traditional gasoline engines found in other
vehicles. Reading this supplement will fa-
miliarize you and other operators of the
vehicle with the unique maintenance and
operating procedures that will prolong the
life of the diesel engine and related sys-
tems.
ENGINE BREAK-IN
RECOMMENDATIONS
∙ Warm up the engine before operating itunder load
∙ Do not operate the engine at idle for extended periods
∙ Prevent engine lugging by selecting the appropriate transmission gear
∙ Monitor the vehicle oil pressure and temperature gauges
∙ Check fluid levels frequently (Oil & Cool- ant)
∙ Vary the throttle position at highway speeds when carrying weight or towing
NOTE:
Extended light or no load operation will
extend the time before the engine
reaches its full efficiency. If the engine is
operated in this manner, reduced fuel
economy and power may be observed.
The aforementioned procedure should be
observed for the first 6,000 miles. The en-
gine run-in is improved by operating the
vehicle under load.
DIESEL FUEL SYSTEM
The diesel engine fuel system is a pressur-
ized two-stage filtration system and con-
sists of: ∙ A frame-mounted primary (stage 1) fuel filter containing water/fuel separator,
electric fuel pump, and water in fuel
drain valve
∙ An engine-mounted secondary (stage 2) fuel filter
∙ A fuel injector for each cylinder (8 total)
∙ A high-pressure fuel pump
∙ A high-pressure fuel rail for each cylin- der bank (2 total)
∙ High-pressure fuel lines from the high- pressure fuel pump to the right bank
fuel rail, right bank fuel rail to the lef t
bank fuel rail, and fuel rails to fuel injec-
tors.
GENERAL INFORMATION
1-2Introduction

The stage 1 fuel filter separates water and
filters impurities from the fuel. The stage 2
fuel filter filters finer impurities from the
diesel fuel. The stage 1 and stage 2 fuel
filters should be changed at the recom-
mended service interval or when indicated
by the information display. For additional
information, refer to “Maintenance and
schedules” and “Instruments and controls”
sections of the Titan Owner’s Manual.
The water/fuel separator should be
drained when indicated by illumination of
the water in fuel warning light.
NOTE:
Proper fuel filter maintenance and
prompt water draining when the water
in the fuel filter warning light illuminates
is essential to prevent damage to fuel
injection system components. Ignoring
the water in fuel warning light can cause
your vehicle to go into a reduced power
mode and has the potential for fuel sys-
tem damage.ENGINE PROTECTION MODE
The diesel engine in this vehicle is equipped
with electronically controlled fuel and
emission systems. Both systems monitor
engine temperatures and pressures, and
then modif y engine operation accordingly.
It is normal for the diesel engine to operate
under these modified conditions for short
durations of time. If the engine operates
under the modified conditions for ex-
tended periods of time, and the service en-
gine soon light is illuminated, have the sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service as
soon as possible.
LUBRICATION SYSTEM
It is important to change the engine oil at
the recommended service intervals to
maintain oil viscosity. Extending the oil and
filter change interval beyond the recom-
mended interval can negatively affect en-
gine performance, fuel economy and en-
gine life. For additional information, refer to
the “Do-it-yourself ” section of this manual.
GLOW PLUGS
The diesel engine glow plug system con-
sists of:∙ Eight Glow Plugs (one per cylinder)
∙ Glow Plug Control Module - Uses input from the Engine Coolant Temperature
Sensor
The glow plugs are energized momentarily
when the ignition is first turned on. The
length of time that the glow plugs are en-
ergized varies depending on engine and
environmental conditions. The required
time for the glow plugs to be energized
decreases as coolant temperature in-
creases. For additional information, refer to
the “Starting and stopping the engine” sec-
tion of this manual.
