GTR-4GT-R Overview
NOTICE
Only use the following specified fluids
and parts in the GT-R to avoid possible
vehicle damage.
ENGINE OIL
Mobil 1 (0W-40) (100% synthetic oil)
Mobil 1 (0W-40) (100% synthetic) is the factory
fill oil. The VR38 engine with its plasma-sprayed
bores was developed using this oil. NISSAN
cannot ensure proper engine operation and
durability if other synthetic oil is used. If Mobil
1 (0W-40) is not available, Mobil 1 (10W-40)
(100% synthetic) may be used; however, some
performance loss may be noticed.
Furthermore, replacement of the engine oil with
MOTUL NISMO COMPETITION OIL type
2193E(5W40) is recommended for the frequent
high performance driving opportunities or when
the engine starting ability during cold weather is
a concern.
NISSAN cannot ensure proper engine operation
and durability if other synthetic oil is used.
The use of additives, chemical materials or
abrasive compounds is prohibited.The use of additives, chemical materials, abra-
sive compounds or other high performance
engine oils may cause internal engine damage.
Engine oil maintenance
.
When the vehicle is delivered, the engine oil
level is 0.39 in (10 mm) below the H mark on
the engine oil dipstick for optimum high
performance driving. The engine oil can be
filled up to the H mark if not engaging in
performance driving.
. Because of the high performance character-
istics of the GT-R engine, more frequent oil
level inspections are necessary. Check the
oil level every 1,800 miles (3,000km) and
adjust as necessary. Also, change the
engine oil based on the driving conditions.
For the information regarding oil replace-
ment intervals, refer to the 2014 NISSAN
GT-R Service and Maintenance Guide.
. Some amount of oil is consumed by your
engine under normal operating conditions,
and oil consumption by itself does not
necessarily indicate any malfunction. If your
rate of oil consumption increases suddenly
or without explanation, NISSAN recom-
mends that you have your vehicle inspected
by a GT-R certified NISSAN dealer. .
For information about the oil replacement
intervals for performance driving, refer to the
interval for replacing oil after high perfor-
mance driving. (
“Additional mainte-
nance items” page GTR-13)
Make sure to replace the oil filter when the
engine oil is changed.
TRANSMISSION OIL
Genuine NISSAN Transmission Oil R35
Special (100% synthetic oil)
The GT-R uses a multiple-disc dual wet clutch
transmission. The specially developed transmis-
sion oil maximizes the friction characteristics of
the clutch and the lubrication of the gear
bearings.
The use of additives is prohibited.
The use of additives or other transmission oil
may cause internal transmission or clutch
damage.
DIFFERENTIAL OIL (front and rear)
Differential Oil R35 COMPETITION type
2189E
Use only the Differential Oil R35 COMPETITION
type 2189E that can keep the oil temperature
low in order to protect all parts of the differential
and maximize the performance of the Limited
GT-R SPECIAL SPECIFICATION
PARTS

Slip Differential (LSD) .
The use of additives is prohibited.
Using additives or any other than the specified
differential oil may cause the oil temperature to
increase and the final drive to be damaged. Also
it may cause vibration and adversely the vehicle
handling characteristics.
BRAKE FLUID
Genuine NISSAN Brake Fluid R35 Special
II
Genuine NISSAN Brake Fluid R35 Special II is
the factory fill brake fluid. The Vehicle Dynamic
Control (VDC) unit and other related parts were
specially designed for this brake fluid. NISSAN
cannot ensure proper operation of the vehicle if
other brake fluid is used.
TIRES AND ROAD WHEELS
Genuine GT-R tires and road wheels
Use only genuine GT-R tires and road wheels.
Tires
The GT-R uses specially designed run-flat tires
and matching road wheels. Use of these
specially developed tires and wheels provides
the greatest potential for maximum performance.
.Using non-genuine GT-R tires may cause powertrain system damage if the vehicle is
driven in a flat tire situation, even if run-flat
tires are used. This may also prevent the
vehicle from being stopped safely.
. Using non-genuine GT-R tires may also
cause tire failure due to excessive heat
buildup caused by tire distortion while
driving.
. Using non-genuine GT-R tires may affect the
operation of the VDC system.
Tire replacement:
. When tire replacement is required, replacing
tires as a set of four with new tires is
recommended. However, if a tire is punctu-
red or damaged, it may be possible to
replace only the damaged tire. Determining
whether one tire or a complete set of tires
should be replaced is based on a number of
factors including tire wear and condition.
Contact your GT-R certified NISSAN dealer.
They can recommend if an individual tire or a
complete set should be replaced.
. The GT-R uses specially designed run-flat
tires which have a rigid side wall. Special
equipment and procedures are required
when replacing these tires. NISSAN recom-
mends that tire replacement be performed at
a GT-R certified NISSAN dealer. .
Specific tire changing equipment must be
used to remove the GT-R tires from the
wheel and to install the GT-R tires onto the
wheel. It is only possible to reuse the tires
when they have no cracks and/or deforma-
tions on the bead portion of the tire. If the
incorrect equipment is used to remove the
GT-R tires from the wheel and to install the
GT-R tires onto the wheel, cracks and
deformation may occur on the bead portion
of the tires meaning that the tires cannot be
reused. Contact a GT-R certified NISSAN
dealer if the tires need to be removed from
the wheels.
. When reusing tires, contact a GT-R certified
NISSAN dealer.
Road wheels
Using non-genuine GT-R wheels may cause the
following:
.vehicle vibration
. the tire coming loose from the wheel during
a flat tire
. reduced wheel lug nut tightness

DRIVING
The information and specifications in this
section apply only when engaging in
performance driving.
Checking the temperature of the
coolant and oils on the multi func-
tion display
When the temperatures of the engine coolant
and oil, and the oil pressure exceed the normal
range, the color of the meter on the multi
function display changes to red to warn the
driver. When engaging in high performance
driving, switch the display to the function meter
to display the temperature of the engine coolant
and oil, and the oil pressure. When the color of
the meter display changes to red, perform cool
down driving. When the values of the tempera-
ture and pressure return to the normal range, the
color of the meter display will turn back to white.
Warning temperature:
. Engine coolant temperature is 2308 F
(1108C) or higher:
If the engine coolant temperature increases
above 2308F (1108C) , the color of the meter
display on the multi function display changes
to red to warn of a possible overheat condition and engine output is reduced.
. Engine oil temperature is 2758F (1358C) or
higher:
If the engine oil temperature is higher than
2758F (1358C), the meter display changes
to red, maximum engine speed is automati-
cally limited to 4,000 rpm, and the transmis-
sion automatically changes from the
&M
position to the&Aposition.
. Transmission oil temperature is 2848 F
(1408C) or higher:
If the transmission oil temperature increases
to over 2848F (1408C) , the color of the
meter display changes to red. However, the
vehicle can continue to be driven until the
temperature reaches 2958F (1468C) . If the
oil temperature exceeds 2848 F (1408C)
while driving (the color of the meter dis-
played in red) , change both the transmission
oil and the differential oil after driving
because these fluids have deteriorated
because of the heat.
Cool down
The information and specifications in this
section apply only when engaging in
performance driving.
Cool down the vehicle to help extend the life of

the vehicle if coolant temperatures are extremely
high. Drive the vehicle at 37 to 50 MPH (60 to
80 km/h), in 5th or 6th gear for 2 to 3 miles (3 to
5 km) and then stop the engine.
Refueling precautions
WARNING
Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire. The fuel tank
is full at the first automatic shutoff.
To maximize vehicle performance, the fuel tank is
located as low as possible to lower the vehicle
center of gravity. The tank is also divided into
two parts. This fuel tank design causes higher
pressures inside the tank than other vehicles so
fuel spillage is possible by trying to top off the
fuel tank after automatic shutoff.
The fuel tank pressure is higher when the vehicle
is hot, especially if the tank is more than half full.
If the cap is opened when the vehicle is hot, it
may cause fuel spray and there may be a hissing
noise. Open the cap slowly, releasing the
pressure from the tank gradually. Also, if the vehicle is refueled when the vehicle is hot, the
fuel pump may automatically shut off before the
tank is full. This does not indicate that there is a
malfunction. Refuel slowly or refuel after the
vehicle has cooled.
INSPECTION AND ADJUSTMENTS
BEFORE DRIVING
The information and specifications in this
section apply only when engaging in
performance driving.
Fluids
.
Check the engine, transmission, differential
and under vehicle surfaces for oil and
coolant leaks.
. Check the fluid levels and adjust as neces-
sary using the specified fluid as described
under the conditions listed in this section.
(
“Recommended fluids and mainte-
nance interval” page GTR-20 ) If you do
not drive under the conditions listed, refer to
the 2014 NISSAN Service and Maintenance
Guide.
. NISSAN recommends to adjust the engine
oil level
*1to be 0.39 in (10 mm) (1/8 gal
(0.5 liters))
*2below the H mark on the
engine oil dipstick. (
*3range is 1.18 in (30
mm)) Before checking the oil level, run the
engine until it reaches operating tempera-
ture and wait at least 5 minutes after turning
off the engine. Make sure the oil level always
remains above the L mark.
When the vehicle is delivered, the engine oil
is set to “H- 0.39 in (10 mm)” for optimal
high performance driving.
. Some amount of oil is consumed by your
engine under normal operating conditions,

distilled water mix is used.
Engine and powertrain
The information and specifications in this
section apply only when engaging in
performance driving.
.Check the engine, transmission, differential
and under the vehicle for oil and coolant
leaks.
. Inspect the areas surrounding of the cata-
lytic converter for heat deterioration.
. Always perform the transmission setting.
After that, adjust the clutch clearance so
that the clearance is less than the clearance
used for daily driving. Your GT-R certified
NISSAN dealer has the necessary informa-
tion and equipment to set the clutch
clearance to the correct specification. The
clearance used for daily driving increases
clutch heat generated during Performance
Driving. This leads to an increase in tem-
perature of the transmission oil. In addition, a
more direct shifting feel can be obtained by
reducing the clutch clearance for Perfor-
mance Driving. The clutch clearance should
be reset to the daily driving specification
after Performance Driving. See your GT-R
certified NISSAN dealer for information.
NOTICE
Failure to have the clutch properly
adjusted before performance driving
may cause the transmission oil tem-
perature to increase which may cause
transmission damage.
. Inspect and confirm the clearance between
the exhaust finisher and rear bumper is more
than 0.24 in (6 mm) (up/down) and more
than 0.20 in (5 mm) (left/right) .
. Inspect the dust boot of the drive shaft
universal joint for cracks or damage.
Suspension and wheel alignment
The information and specifications in this
section apply only when engaging in
performance driving.
.Check the steering and suspension system
and other links for loose and/or damaged
parts.
. Measure and adjust the wheel alignment.
(
“Wheel alignment” page GTR-10)
Contact a GT-R certified NISSAN dealer to
adjust the wheel alignment to the recom-
mended setting for high performance driv-
ing. Preventing toe-out:
Toe-out can cause uneven tire wear or
damage to areas inside the tires due to
high heat. Be sure to have the wheel
alignment toe-in setting checked and ad-
justed by your GT-R certified NISSAN
dealer before any performance driving on
closed circuit tracks. Obey all traffic laws
when on public roads.

the wheels. The tire may slip on the wheel if
the vehicle is driven in these conditions
before 48 hours have passed. If the tire slips
on the wheel, the wheel/tire assembly will be
out of balance and will require rebalancing.
Brakes
The information and specifications in this
section apply only when engaging in
performance driving.
.Check for the heat deterioration of the
brakes and parts around the brakes.
. It is recommended that you remove air from
the brake system after any of the following:
— When engaging in high performance
driving for the first time after purchasing
a new vehicle.
— After replacing the brake fluid.
— When engaging in high performance driving for a sustained period of time. It
is recommended that bleeding the brake
be performed when the brake calipers
are hot (about 2128F (1008C)) .
Brake pad:
NISSAN recommends adding an additional
cross spring to the front calipers before enga-
ging in performance driving. The additional
spring reduces brake pad movement resulting from cornering forces and will reduce the stroke
of the brake pedal. Contact a GT-R certified
NISSAN dealer to purchase the spring and
arrange installation. If a cross spring is added, a
clattering or squeaking sound may be heard on
rare occasions.
Brake pad break-in procedure:
NISSAN recommends that a special brake pad
break-in procedure be performed before enga-
ging in performance driving. Contact a GT-R
certified NISSAN dealer for details.
INSPECTION AND ADJUSTMENTS
AFTER DRIVING
The information and specifications in this
section apply only when engaging in

NOTICE
At the completion of performance driv-
ing, all fluid and other adjustments
should be returned to the normal fluid
specifications as shown in the “Main-
tenance and do-it-yourself” section of
this manual.
Fluids
