Aftermarket fuel additivesGUID-E35DB2CE-4B2A-43A8-8EFC-14E1686FBCF2
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 tipsGUID-AB3A7D1F-9988-4771-A998-C4AEF3B5353FUsing 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, it is recommended you havea GT-R certified NISSAN dealer correct the
condition. Failure to correct the condition
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 consumption 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-

Selecting the correct oilGUID-878F1CD4-7741-4A11-ABA4-AA924EE0D79CIt is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance.
(
ªCapacities and recommended fluids/lu-
bricantsº page 9-2)
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 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.
NOTICE
Using an engine oil other than that
specified could adversely affect the
engine. See the 2017 NISSAN GT-R
Warranty Information Booklet for de-
tails and exclusions.
Oil additivesGUID-74B2A1BE-EF2D-49ED-86BB-0BA5671DA592NISSAN 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 followed.
Oil which may contain foreign matter or has
been previously used should not be used.
Oil viscosityGUID-A93C5DED-BCB7-4F12-A432-606D02BBE8D6The engine oil viscosity or thickness changes
with temperature. Because of this, it is important
