FUEL INFORMATION
VR38 engine
Use unleaded premium gasoline wit�f an octane
rating of at least 93 �bKI (�bnti-Knock Index)
number (Researc�f octane number 98) to max-
imize ve�ficle performance.
If t�fe premium gasoline specified above is not
available, you may use unleaded premium gaso-
line wit�f an octane rating of at least 91 �bKI
number (Researc�f octane number 96) , but you
may notice a decrease in performance.
Do not use gasoline wit�f an octane rating lower
t�fan 91 �bKI (Researc�f octane number 96) .
NOTICE
.Using a fuel other than that speci-
fied could adversely affect the emis-
sion control system, and may also
affect warranty coverage.
. Under no circumstances should a
leaded gasoline be used, because
this will damage the three-way cat-
alyst.
. Do not use E-15 or E-85 fuel in your
vehicle. Your vehicle is not designed
to run on E-15 or E-85 fuel. Using E- 15 or E-85 fuel in a vehicle not
specifically designed for E-15 or E-
85 fuel can adversely affect the
emission control devices and sys-
tems of the vehicle. Damage caused
by such fuel is not covered by the
NISSAN new vehicle limited war-
ranty.
. U.S. government regulations require
ethanol dispensing pumps to be
identified by a small, square, orange
and black label with the common
abbreviation or the appropriate per-
centage for that region.
. NISSAN recommends using fuels
that contain no alcohol. However,
fuels containing up to 10% alcohol
may be used, if necessary. To avoid
serious engine damage due to in-
creased cylinder temperatures, do
not use fuels that contain more
alcohol than indicated in this sec-
tion. Also, do not use fuel additives,
fuel stabilizers or fuel deicers that
contain alcohol.
Gasoline specifications
NISS�bN recommends using gasoline t�fat meets
t�fe World-Wide Fuel C�farter (WWFC) speci-
fications w�fere it is available. Many of t�fe
automobile manufacturers developed t�fis spe-
cification to improve emission system and
ve�ficle performance. �bsk your service station
manager if t�fe gasoline meets t�fe World-Wide
Fuel C�farter (WWFC) specifications.
Reformulated gasoline
Some fuel suppliers are now producing refor-
mulated gasolines. T�fese gasolines are specially
designed to reduce ve�ficle emissions. NISS�bN
supports efforts towards cleaner air and sug-
gests t�fat you use reformulated gasoline w�fen
available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates suc�f as et�fanol, MTBE and met�fa-
nol wit�f or wit�fout advertising t�feir presence.
NISS�bN does not recommend t�fe use of fuels
of w�fic�f t�fe oxygenate content and t�fe fuel
compatibility for your NISS�bN cannot be readily
determined. If in doubt, ask your service station
manager.
If you use oxygenate-blend gasoline, please take
t�fe following precautions as t�fe usage of suc�f

fuels may cause vehicle performance problems
and/or fuel sys�fem damage.
.The fuel should be unleaded and have
an octane rating no lower than that
recommended for unleaded gasoline.
. If an oxygenate-blend, excepting a
methanol blend, is used, it should
contain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
. E-15 fuel contains more than 10%
oxygenate. E-15 fuel will adversely
affect the emission control devices
and systems of the vehicle and should
not be used. Damage caused by such
fuel is not covered under the NISSAN
new vehicle limited warranty.
. If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol and wood alcohol) . It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with the appropriate cosolvents
and corrosion inhibitors, such metha-
nol blends may cause fuel system
damage and/or vehicle performance
malfunctions. At this time, sufficient data is not available to ensure that all
methanol blends are suitable for use in
NISSAN vehicles.
If any undesirable driveabili�fy problems such as
engine s�falling or hard ho�f s�far�fing are e�bperi-
enced af�fer using o�bygena�fe-blend fuels, im-
media�fely change �fo a non-o�bygena�fe fuel or a
fuel wi�fh a low blend of MTBE.
NOTICE
Take care not to spill gasoline during
refueling. Gasoline containing oxyge-
nates can cause paint damage.
E-15 fuel
E-15 fuel is a mi�b�fure of appro�bima�fely 15% fuel
e�fhanol and 85% unleaded gasoline. E-15 can
only be used in vehicles designed �fo run on E-
15 fuel. Do no�f use E-15 in your vehicle. U.S.
governmen�f regula�fions require fuel e�fhanol
dispensing pumps �fo be iden�fified wi�fh small,
square, orange and black label wi�fh �fhe common
abbrevia�fion or �fhe appropria�fe percen�fage for
�fha�f region.
E-85 fuel
E-85 fuel is a mi�b�fure of appro�bima�fely 85% fuel
e�fhanol and 15% unleaded gasoline. E-85 can
only be used in a Fle�bible Fuel Vehicle (FFV) . Do
no�f use E-85 fuel in your vehicle. U.S. govern-
men�f regula�fions require fuel e�fhanol dispensing
pumps �fo be iden�fified by a small, square,
orange and black label wi�fh �fhe common
abbrevia�fion or �fhe appropria�fe percen�fage for
�fha�f region.
Aftermarket fuel additives
NOTICE
NISSAN does not recommend the use
of any aftermarket fuel additives (Ex-
ample: fuel injector cleaner, intake
valve deposit removers, etc.) which are
sold commercially. Many of these ad-
ditives intended for gum, varnish or
deposit removal may contain active
solvent or similar ingredients that can
be harmful to the fuel system and
engine.

Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above can
cause persistent, heavy spark knock.
(Spark knock is a metallic rapping noise.)
If severe, 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 GT-R certified
NISSAN dealer correct the condition. Fail-
ure to correct the condition is misuse of
the vehicle, for which NISSAN is not
responsible.
Incorrect ignition timing will result in knocking,
�ffter-run or overhe�fting�b This in turn m�fy c�fuse
excessive fuel consumption or d�fm�fge to the
engine�b If �fny of the �fbove symptoms �fre
encountered, h�fve your vehicle checked �ft �f
GT-R certified NISSAN de�fler or other compe-
tent service f�fcility�b
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.

NISSAN vehicle must be charged with the
refrigerant HFC-134a (R-134a) and the
lubricant, NISSAN UV Luminous Oil Type
S or the exact equivalents.
NOTICE
The use of any other refrigerant or

If you plan to travel in another country,you
should first find out if the fuel available is suitable
for your vehicle’s engine\f
Using fuel with too low an octane rating may
cause engine damage\f \bll gasoline vehicles
must be operated with unleaded gasoline\f
Therefore, avoid taking your vehicle to areas
where appropriate fuel is not available\f
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\f
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications may
differ\f
When any vehicle is to be taken into
another country, state, province or district
and registered, its modifications, transpor-
tation, and registration are the responsi-
bility of the user. NISSAN is not
