ethanol NISSAN 350Z 2004 Owner´s Manual

FUEL RECOMMENDATIONUse unleaded premium gasoline with an octane
rating of at least 91 AKI (Anti-Knock Index)
number (Research octane number 96).
If premium gasoline is not available, unleaded
regular gasoline with an octane rating of 87 AKI
number (Research octane number 91) may be
temporarily used, but only under the following
precautions:

Have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as pos-
sible.

Avoid full throttle driving and abrupt accelera-
tion.
However, for maximum vehicle perfor-
mance, the use of unleaded premium gaso-
line is recommended.
CAUTION
Using a fuel other than that specified
could adversely affect the emission con-
trol devices and systems, and could also
affect the warranty coverage.Under no circumstances should a
leaded gasoline be used, since this will
damage the three-way catalyst.
Reformulated gasolineSome fuel suppliers are now producing reformu-
lated gasolines. These gasolines are specially
designed to reduce vehicle emissions. NISSAN
supports efforts towards cleaner air and sug-
gests that you use reformulated gasoline when
available.Gasoline containing oxygenatesSome fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and metha-
nol with or without advertising their presence.
NISSAN does not recommend the use of fuels of
which the oxygenate content and the fuel com-
patibility for your NISSAN cannot be readily
determined. If in doubt, ask your service station
manager.
If you use oxygenate-blend gasoline, please take
the following precautions as the usage of such
fuels may cause vehicle performance problems
and/or fuel system damage.

The fuel should be unleaded and have
an octane rating no lower than thatrecommended for unleaded gasoline.

If an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)

If a methanol blend is used, it should
contain no more than 5% methanol (me-
thyl alcohol, wood alcohol). It should
also contain a suitable amount of ap-
propriate cosolvents and corrosion in-
hibitors. If not properly formulated with
appropriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or ve-
hicle performance problems. 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 and hard hot starting are experi-
enced after using oxygenate-blend fuels, imme-
diately change to a non-oxygenate fuel or a fuel
with a low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
