2021 NISSAN GT-R oil temperature

Cool downThe 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 DRIVINGThe information and specifications in
this section apply only when engaging
in performance driving.Fluids.
Check the engine, transmission, differ-
ential and under vehicle surfaces for
oil and coolant leaks.
. Check the fluid levels and adjust as
necessary using the specified fluid as
described under the conditions listed
in this section.(
“Recommended
fluids and maintenance interval” page GTR-20) If you do not drive under the
conditions listed, refer to the “9. Main-
tenance and schedules” section of this
manual.

to be 0.39 in (10
mm) (1/8 gal (0.5 liters))
below the H
mark on the engine oil dipstick. (
range is 1.18 in (30 mm).) Before
checking the oil level, run the engine
until it reaches operating temperature
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

Check the coolant level in the pressurized
coolant reservoir. Adjust the level so that
the fluid is between the MAX and MIN
markings. For the coolant, use genuine
NISSAN Long Life coolant or equivalent.
(On delivery of new vehicle, the reservoir
is filled to the MIN level. Be sure to
replenish approximately 3/8 US quart
(0.3 to 0.4 liter) of coolant.)
NOTICE
Do not overfill the coolant. This may
increase the pressure in the cooling
system and cause coolant leaks.
To maximize vehicle performance, the
coolant mixture ratio should be a combi-
nation of 30% coolant antifreeze and 70%
demineralized or distilled water for max-
imum cooling system performance re-
gardless of ambient temperatures.
If ambient temperatures are anticipated
below 5°F (−15°C), make sure a proper
mixture ratio of 50% antifreeze and 50%
demineralized or distilled water mix is
used.Engine and powertrainThe information and specifications in
this section apply only when engaging in performance driving.
.
Check the engine, transmission, differ-
ential and under the vehicle for oil and
coolant leaks.
. Inspect the areas surrounding of the
catalytic converter for heat deteriora-
tion.
. 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 information
and equipment to set the clutch
clearance to the correct specification.
The clearance used for daily driving
increases clutch heat generated dur-
ing Performance Driving. This leads to
an increase in temperature of the
transmission oil. In addition, a more
direct shifting feel can be obtained by
reducing the clutch clearance for
Performance Driving. The clutch clear-
ance should be reset to the daily
driving specification after Perfor-
mance Driving. It is recommended
you see a 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 alignmentThe 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 align-
ment. (
“Wheel alignment” page
GTR-10) It is recommended you con-
tact a GT-R certified NISSAN dealer to
adjust the wheel alignment to the
recommended setting for high perfor-

position, and to
4,000 rpm when the engine oil or
coolant temperature is low or higher
than normal.
. If the ignition switch is pushed
before the shift lever is moved to
the
position, the ignition switch
will not change to the OFF position.
If this occurs, the SHIFT
warning
display appears on the vehicle in-
formation display. When stopping
the engine, be sure to move the shift
lever to the
position and then
push the ignition switch. Failure to
do so may result in discharge of the
battery. (“Shift “P” warning”
page 2-46)
. If the shift lever was in the
position when the engine was
stopped, then be sure to move the
shift lever to the
position before
starting the engine the next time. If the engine is started with the shift
lever in the
position, then it may
not be possible to drive the vehicle
even when the shift lever is moved
to the
position. If this
occurs, the SHIFTwarning appears
on the vehicle information display.
(
“Shift “P” warning” page 2-46)
CAUTION
If the engine was stopped soon
when the engine is hot, the cooling
fan may operate for approximately 2
minutes after the engine was
stopped to cool the components in
the engine compartment. When the
cooling fan is operating, be sure that
hands or other items do not get
caught in it.
DUAL CLUTCH TRANSMISSIONThe GT-R dual clutch transmission is a
newly-developed system that uses an
electronically controlled multiple-disc
wet clutch attached to the highly efficient
manual transmission. This transmission
has two driving modes.

down to 1st gear similar to a manual
transmission vehicle.
The GT-R dual clutch transmission was
developed specifically to maximize vehi-
cle performance and driving enjoyment.
The GT-R transmission components were
designed using different engineering
standards than typical passenger car
transmissions. Because of this, the GT-R
has different operating characteristics,
and various rattle noises may be heard
during some driving conditions because

you may not be able to shift gear
or it may take longer to shift gear.
Make sure to depress the brake
pedal and check that the vehicle
has stopped before shifting.
CAUTION
. Because the vehicle includes a
dual clutch transmission that
automatically controls the clutch
and shifting operation of the
manual transmission, whenever
the shift lever is in a position
other than

, the vehicle will
begin to move slowly, in the same
way as when the clutch in a
manual transmission vehicle is
partially engaged. Keep the brake
pedal firmly depressed when the vehicle is stopped. In some cir-
cumstances the vehicle may not
start moving on its own, however
this does not indicate that there
is a malfunction.
NOTICE
.
To avoid possible damage to your
vehicle; when stopping the vehi-
cle on an uphill grade, do not hold
the vehicle in place by depressing
the accelerator pedal. Doing so
may cause the clutch to overheat
and result in transmission da-
mage. Use the brakes to prevent
the vehicle from moving.
. The GT-R dual clutch transmis-
sion is provided with a dry sump
lubrication system that improves
efficiency and ensures reliability
under high g-force conditions.
When oil viscosity is high at low
temperatures, it takes longer for
all components to be sufficiently
lubricated. Thus, when the trans-
mission temperature is low (ap-
proximately 104°F (40°C), do not
accelerate rapidly or run the en-
gine faster than 4,000 rpm.

Oil viscosityThe engine oil viscosity or thickness
changes with temperature. Because of
this, it is important that the engine oil
viscosity be selected based on the tem-
peratures at which the vehicle will be
operated before the next oil change.
Choosing an oil viscosity other than that
recommended could cause serious en-
gine damage.Selecting the correct oil filterYour new vehicle is equipped with a high-
quality genuine NISSAN oil filter. NISSAN
recommends to use the genuine NISSAN
oil filter for the reason described in

AIR CONDITIONING SYSTEM RE-
FRIGERANT AND OIL RECOMMEN-
DATIONSThe air conditioner system in your
NISSAN vehicle must be charged with
the refrigerant HFO-1234yf (R-1234yf)
and NISSAN A/C System Oil VC100YF
(PAG) or the exact equivalents.
CAUTION
The use of any other refrigerant or oil
will cause severe damage to the air
conditioning system and will require
the replacement of all air conditioner
system components.
The refrigerant HFO-1234yf (R-1234yf) in
your NISSAN vehicle does not harm the
earth’s ozone layer. Although this refrig-
erant does not affect the earth’s atmo-
sphere, certain government regulations
require the recovery and recycling of any
refrigerant during automotive air condi-
tioner system service. Air conditioner
system should only be serviced by trained
and certified technicians to ensure proper
and safe operation (SAE J2845). Your GT-R
certified NISSAN dealer has the trained
technicians and equipment needed to
recover and recycle your air conditioner
system refrigerant. Only new and
SAEJ2842 certified evaporator(s) shall be
used as replacement parts.
A damaged or leaking air conditioning
evaporator shall never be repaired or
replaced with one removed from a used
or salvaged vehicle. To replace a da-
maged or leaking evaporator, use only
new and SAE J2842 certified evaporator
