NOTICE

Take care not to spill gasoline during

refueling. Gasoline containing oxyge-

nates can cause paint damage.

E-85 fuel

E-85 fuel is a mixture of approximately 85% fuel

ethanol and 15% unleaded gasoline. E-85 can

only be used in a Flexible Fuel Vehicle (FFV). Do

not use E-85 fuel in your vehicle. U.S. govern-

ment regulations require fuel ethanol dispensing

pumps

to

be

identified

by

a

small,

square,

orange

and

black

label

with

the

common

abbreviation or the appropriate percentage for

that 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,

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, have your vehicle checked at a

GT-R certified NISSAN dealer or other compe-

tent 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 oil

It is essential to choose the correct grade,

quality,

and

viscosity

engine

oil

to

ensure

satisfactory

engine

life

and

performance.

(

“CAPACITIES

AND

RECOMMENDED

FUEL/LUBRICANTS” 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; how-

ever, some performance loss may be noticed.

NOTICE

Using

an

engine

oil

other

than

that

specified

could

adversely

affect

the

engine.

See

the

2009

Nissan

GT-R

Warranty Information Booklet for de-

tails and exclusions.

Oil additives

NISSAN 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.
