2006 NISSAN TITAN 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 se-
vere, 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, 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, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer.
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.
CAUTION
cYour vehicle is not designed to run on
E-85 fuel. Using E-85 fuel in a vehicle
not specifically designed for E-85 fuel
can damage fuel system components
and is not covered by the NISSAN new
vehicle limited warranty.
cE-85 is a mixture of approximately 85%
fuel ethanol and 15% unleaded
gasoline.
cU.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and
black label with the common abbrevia-
tion or the appropriate percentage for
that region.
FLEXIBLE FUEL VEHICLE (FFV) FUEL
RECOMMENDATION (if so equipped)
Your vehicle is designed to use (E-85) Fuel Etha-
nol, “Regular” unleaded regular gasoline or any
percentage of the two fuels combined.
U.S. government regulations require Fuel
Ethanol dispensing pumps to have a small,
square, orange and black label with the
common abbreviation or the appropriate
percentage for that region.
CAUTION
Use of other fuels such as Fuel Methanol
may cause powertrain damage or a loss of
vehicle performance.
General information
This information is for Flexible Fuel vehicles (FFV)
only. FFV vehicles can be identified by the fuel
filler door label that states Ethanol (E-85) or
Unleaded Gasoline Only. This section only cov-
ers those subjects that are unique to Flexible Fuel
vehicles.
CAUTION
Only vehicles with the E-85 filler door la-
bel can operate on E-85. Fuel system or
other damage can occur if E-85 is used in
vehicles that are not designed to run on
E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% fuel etha-
nol and 15% unleaded gasoline.

WARNING
cEthanol vapors are extremely flam-
mable and could cause serious per-
sonal injury.
cNever have any smoking materials lit in
or near the vehicle when removing the
fuel filler cap or filling the tank.
cDo not use E-85 as a cleaning agent and
never use it near an open flame.
Fuel requirements
Your vehicle will operate on both unleaded regu-
lar gasoline with an octane rating of at least 87
AKI (Anti-Knock Index) number (Research oc-
tane number 91) , or E-85 fuel, or any mixture of
these two.
For the best starting and vehicle driveability re-
sults, do not continually switch between E-85
and unleaded regular gasoline. If you must switch
fuels, NISSAN recommends the following:
cdo not switch when the fuel gauge indicates
less than 1/4 full
cadd more than 5 gallons of fuel
coperate the vehicle immediately after refuel-
ing for a period of at least 5 minutesNOTE:
When the ambient temperature is above
90°F (32°C) , you may experience hard start-
ing and rough idle following start up even if
the above recommendations are followed.
Selection of engine oil
For best performance and protection of your ve-
hicle, use only engine oils that meet the following
requirements:
cEngine Oil Selection for Operating on
E-85
If you operate the vehicle on E-85 fuel, use only
SAE 5W-30 viscosity oil for all temperatures.E-
quivalent commercial Flexible Fuel engine oils
may be labeled as Flexible Fuel (FFV) or Alterna-
tive Fuel (AFV) . These engine oils may be satis-
factory if they meet NISSAN standards.
The 5W-30 engine oil installed at the factory
meets the NISSAN requirements for Flexible Fuel
engine oil.
SAE 5W-30 engine oil is preferred for use in
Flexible Fuel engines.
CAUTION
If Flexible Fuel engine oil is not used
when using E-85, engine wear may be
increased significantly. This may affect
the warranty coverage.
cEngine Oil Selection for Operating on
Gasoline
If you operate the vehicle on regular unleaded
gasoline ONLY use oil that meets certified API
(American Petroleum Institute) Quality as out-
lined in “Engine Oil and Oil Filter Recommenda-
tion” later in this section.
Starting
The characteristics of E-85 fuel make it unsuit-
able for use when ambient temperatures fall be-
low 0°F (-18°C) . In the range of 0°F (-18°C) to
32°F (0°C) , you may experience an increase in
the time it takes for you engine to start, and a
deterioration in drivability (sags and/or hesita-
tions) until the engine is fully warmed up.
Fuel consumption
Because E-85 fuel contains less energy per gal-
lon than gasoline, you will experience an increase
in fuel consumption. You can expect your fuel
mileage to decrease by about 30% compared to
gasoline operation.

Replacement parts
Many components in your Flexible Fuel Vehicle
(FFV) are designed to be compatible with etha-
nol. Always be sure that your vehicle is serviced
with correct ethanol compatible parts.
CAUTION
Replacing fuel system components with
non-ethanol compatible components can
damage your vehicle and may also affect
the warranty coverage.
Maintenance
If you operate your vehicle using E-85 fuel, follow
the correct maintenance log shown in the
“NISSAN Service and Maintenance Guide”.
CAUTION
Do not use ethanol mixture greater than
85% in your vehicle. It will cause difficulty
in cold starting and may affect drivability.
ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to choose engine oil with the cor-
rect quality and viscosity to ensure satisfactory
engine life and performance. NISSAN recom-
mends the use of a low friction oil (energy con-
serving oil) in order to improve fuel economy and
conserve 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 Petro-
leum Institute (API) CERTIFICATION MARK onthe front of the container should be used. This
type of oil supersedes the existing API SG, SH, or
SJ and Energy Conserving II categories.
If you cannot find engine oil with the API CERTI-
FICATION MARK, use API grade SL Energy
Conserving oil. An oil with a single designation
SL, or in combination with other categories (for
example, SL/CF) may also be used if one with the
API CERTIFICATION MARK cannot be found. An
ILSAC grade GF-II or GF-III oil can also be used.
NISSAN recommends mineral based oils. These
oils must, however, meet the API quality and SAE
viscosity ratings specified for your vehicle.

NOTE:
If you operate the vehicle on E-85 fuel only
use oil that meets the NISSAN require-
ments for Flexible Fuel as outlined under
“Engine Oil Selection for Operating on
E-85” in “Flexible Fuel Vehicle (FFV) Fuel
Recommendation” earlier in this section.
Oil additives
NISSAN does not recommend the use of oil
additives. The use of an oil additive is not neces-
sary when the proper oil type is used and main-
tenance 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 oper-
ated before the next oil change. The chart “Rec-
ommended SAE viscosity number” shows the
recommended oil viscosities for the expected
ambient temperatures. Choosing an oil viscosity
other than that recommended could cause seri-
ous engine damage.
Selecting the correct oil filter
Your new NISSAN vehicle is equipped with a
high-quality genuine NISSAN oil filter. When re-
placing, use a genuine NISSAN oil filter or its
equivalent for the reason described in “Change
intervals”.
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 engine oil and filters
that are not of the specified 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 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 recommended 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:
crepeated short distance driving at cold out-
side temperatures
cdriving in dusty conditions
cextensive idling
ctowing a trailer
cstop and go commuting

When planning to drive your NISSAN ve-
hicle in another country,you should first find
out if the fuel available is suitable for your vehi-
cle’s engine.
Using fuel with an octane rating that is too low
may cause engine damage. All gasoline vehicles
must be operated with unleaded gasoline. There-
fore, 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 modify the
vehicle to meet local laws and regulations.
The laws and regulations for motor vehicle emis-
sion control and safety standards vary according
to the country, state, province or district; there-
fore, vehicle specifications may differ.
When any vehicle is to be taken into an-
other country, state, province or district
and registered, its modifications, transpor-
tation, and registration are the responsibil-
ity of the user. NISSAN is not responsible
for any inconvenience that may result.

WARNING
Overloading or improper loading of a
trailer and its cargo can adversely affect
vehicle handling, braking and perfor-
mance and may lead to accidents.
CAUTION
cDo not tow a trailer or haul a heavy load
for the first 500 miles (800 km) . Your
engine, axle or other parts could be
damaged.
cFor the first 500 miles (800 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 vehicle wear in at the
heavier loads.
Your new vehicle was designed to be used pri-
marily to carry passengers and cargo. Remember
that towing a trailer places additional loads on
your vehicle’s engine, drive train, steering, brak-
ing and other systems.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed the
value specified in the following Towing
Load/Specification Chart found later in this sec-
tion. The total trailer load equals trailer weight
plus its cargo weight.
cWhen towing a trailer load of 1,000 lbs.
(454 kg) or more, trailers with a brake sys-
tem MUST be used.
The maximum GCWR (Gross Combined Weight
Rating) should not exceed the value specified in
the following Towing Load/ Specification Chart.
The GCWR equals the combined weight of the
towing vehicle (including passengers and cargo)
plus the total trailer load. Towing loads greater
than these or using improper towing equipment
could adversely affect vehicle handling, braking
and performance.
The ability of your vehicle to tow a trailer is not
only related to the maximum trailer loads, but also
the places you plan to tow. Tow weights appro-
priate for level highway driving may have to be
reduced on very steep grades or in low traction
situations (for example, on slippery boat ramps) .Temperature conditions can also affect towing.
For example, towing a heavy trailer in high outside
temperatures on graded roads can affect engine
performance and cause overheating. The engine
protection mode, which helps reduce the chance
of engine damage, could activate and automati-
cally decrease engine power. Vehicle speed may
decrease under high load. Plan your trip carefully
to account for trailer and vehicle load, weather
and road conditions.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a col-
lision. Be especially careful when driving.
Pull to the side of the road to a safe area.
Allow the engine to cool and return to
normal operation. See “If your vehicle
overheats” in the “In case of emergency”
section of this manual.
CAUTION
Vehicle damage resulting from improper
towing procedures is not covered by
NISSAN warranties.
