ENGINE COMPARTMENT CHECK
LOCATIONS
6-2Do-it-yourself
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 after a shorter time interval than
if your vehicle was operating on pure
petroleum-based diesel. For additional in-
formation, refer to the “Maintenance” sec-
tion in the “Titan Owner’s Manual.”
CHECKING ENGINE OIL LEVEL
NOTE:
The factory fill oil may include a red dye
that is added for manufacturing quality pro-
cesses. The dye makes the oil appear to be
red. This is normal. The red dye will be
flushed from the engine after approxi-
mately 4–5 oil changes.1. Park the vehicle on a level surface and apply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature. 3. Turn off the engine.
Wait more than
10 minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re- insert it all the way.

5. Remove the dipstick again and check the oillevel. It should be between the high and low
marks
B. This is the normal operating oil
level range. If the oil level is below the low
mark
A, remove the oil filler cap and pour
recommended oil through the opening. Do
not overfill
C.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the severity
of operating conditions.
CAUTION
Oil level should be checked regularly. Op-
erating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.

NOTE:
The factory fill oil may include a red dye
that is added for manufacturing quality pro-
cesses. The dye makes the oil appear to be
red. This is normal. The red dye will be
flushed from the engine after approxi-
mately 4–5 oil changes.1. Park the vehicle on a level surface and apply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature, then turn it off.
3. Remove the oil filler cap
Aby turning it
counterclockwise.
4. Place a large drain pan under the drain plug
B.
5. Remove the drain plug
Bwith a wrench by
turning it counterclockwise and completely
drain the oil.
Remove and replace the engine oil filter at
this time. For additional information, refer to
“Changing engine oil filter” in this section.
● Waste oil must be disposed of prop-
erly.
● Check your local regulations.
WARNING
●Prolonged and repeated contact with
used engine oil may cause skin cancer.
● Try to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
● Keep used engine oil out of reach of
children.
CAUTION
Be careful not to burn yourself. The engine
oil may be hot.
6. Clean and reinstall the drain plug. Securely tighten the drain plug with a wrench. Do not
use excessive force.
Drain plug tightening torque: 25 ft-lb (34 N·m)
7. Refill engine with recommended oil through the oil filler opening, then install the oil filler
cap securely.
For additional information on drain and refill
capacity, refer to “Recommended
fluids/lubricants and capacities” in the
“Technical and consumer information” sec-
tion of this manual. The drain and refill capacity depends on the
oil temperature and drain time. Use these
specifications for reference only. Always use
the dipstick to determine when the proper
amount of oil is in the engine.
8. Start the engine. Check for leakage around the drain plug and oil filter. Correct as re-
quired.
9. Turn the engine off and wait more than 10 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
Do-it-yourself6-7
CAUTION
Be sure to remove any old gasket material
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 resistance 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 removal.
12. Turn the engine off and wait more than 10 minutes. Check the oil level. Add engine
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 after a shorter time interval than

tion in the “Titan Owner’s Manual.”
FUEL FILTER REPLACEMENT (stage

NOTE:
● It is possible the “Low Fuel Pressure
Service Fuel System” message will dis-
play on the vehicle information display
after fuel filter replacement due to air
being introduced into the fuel system.

Diesel Exhaust Fluid (DEF) storage
The shelf life of DEF is limited, whether it is stored
in containers or in the vehicle’s diesel exhaust
fluid tank. There are a variety of factors that can
contribute to reducing DEF’s shelf life, particu-
larly temperature and duration.
To increase shelf life when storing DEF, keep the
following in mind:● Avoid contamination by storing in sealed
containers.
● Protect from direct sunlight.
● Store DEF at temperatures between 23°F
and 77°F (-5°C and 25°C) to protect from
overheating or freezing.
DEF has a minimum expected shelf life of
18 months, but its shelf life will be reduced if the
above conditions are not met.
It will be necessary to recheck the DEF concen-
tration if it has been stored for an extensive period
of time, or if it has been exposed to water. More
information can be found in the manufacturer’s
Owner’s Manual.
Diesel Exhaust Fluid (DEF) disposal
Always check with local authorities for regula-
tions on proper disposing processes and re-
quirements for DEF.
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 after approxi-
mately 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 infor-
mation, refer to “Recommended fluids/lubricants
and capacities” in this section. NISSAN recom-
mends the use of an energy conserving oil in
order to improve fuel economy.
Select only engine oils that meet the Cummins®
Engineering Standard (CES) classification (CES
20081) and American Petroleum 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.
