The higher shift speeds in the

The quickest shifting in the R mode with the transmission in the
position is available when the engine speed is high.
However, the transmission may shift more slowly when the engine speed is low.
Mechanical Limited Slip
Differential (LSD) If the vehicle accelerates from a stop with the steering wheel turned half a turn in cold temperatures, the inner wheel tire
may slip and some noise or vibration may be heard. This phenomenon occurs because the viscosity of the differential oil
becomes thicker and the Limited Slip Differential (LSD) operates with increasing load. When the steering wheel is returned
to the straight ahead position or the differential oil warms up, the noise and vibration decrease.

Make sure to depress the brake

begin to move slowly, in the same
way as when the clutch in a

pedal firmly depressed when the vehicle is stopped. In some cir-

this does not indicate that there

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.

system. Note that while some fuel pumps
label MMT content, not all do, so you may
have to consult your gasoline retailer for
more details.Aftermarket fuel additives
NOTICE
NISSAN does not recommend the use
of any aftermarket fuel additives
(Example: fuel injector cleaner, in-
take valve deposit removers, etc.)
which are sold commercially. Many
of these additives intended for gum,
varnish or deposit removal may con-
tain active solvent or similar ingre-
dients that can be harmful to the fuel
system and engine.Octane rating tipsUsing unleaded gasoline with an octane
rating lower than recommended above
can cause persistent, heavy spark
knock. (Spark knock is a metallic rap-
ping noise.) If severe, this can lead to
engine damage. If you detect a persis-
tent 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 levelroads, it is recommended you have a
GT-R certified NISSAN dealer correct the
condition. Failure to correct the condi-
tion is misuse of the vehicle, for which
NISSAN is not responsible.
Incorrect ignition timing will result in
knocking, after-run or overheating. This
in turn may cause excessive fuel con-
sumption or damage to the engine. If any
of the above symptoms are encountered,
it is recommended you have your vehicle
checked at a GT-R certified NISSAN dealer
or other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
no cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time under
heavy engine load.
ENGINE OIL AND OIL FILTER RE-
COMMENDATION
Selecting the correct oilIt is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance.
(
“Capacities and recommended
fluids/lubricants” page 10-2)
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 0W-40 non-equivalent synthetic oil
is used. If Mobil 1 (0W-40) or equivalent is
not available, Mobil 1 (10W-40) (100%
synthetic) or equivalent may be used;
however, some performance loss may
be noticed.
NOTICE
Using an engine oil other than that
specified could adversely affect the
engine. See the 2021 NISSAN GT-R
Warranty Information Booklet for
details and exclusions.Oil additivesNISSAN does not recommend the use of
oil additives. The use of an oil additive is
not necessary when the proper oil type is
used and maintenance intervals are fol-
lowed.
Oil which may contain foreign matter or
has been previously used should not be
used.

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
change intervals.Change intervals
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
