. 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 driveability problems such as
engine stalling or hard hot starting are experi-
enced after using oxygenate-blend fuels, im-
mediately change to a non-oxygenate fuel or a
fuel with a low blend of MTBE.
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.
