presence. Nissan does not recommend the
use of fuels of which the oxygenate content
and the fuel compatibility 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 perfor-
mance problems and/or fuel system dam-
age.
cThe fuel should be unleaded and have
an octane rating no lower than that
recommended for unleaded gasoline.
cIf an oxygenate-blend other than a
methanol blend is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
cIf a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system dam-age and/or vehicle performance prob-
lems. At this time, sufficient data is
not available to ensure that all metha-
nol blends are suitable for use in NIS-
SAN vehicles.
If any driveability problems such as engine
stalling and difficult hot-starting are experi-
enced after using oxygenate-blend fuels,
immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygen-
ates can cause paint damage.
Aftermarket Fuel Additives
NISSAN does not recommend the use of
any fuel additives (i.e.: fuel injector cleaner,
octane booster, intake valve deposit remov-
ers, etc.) which are sold commercially.
Many of these additives intended for gum,
varnish or deposit removal may contain
active solvents or similar ingredients that
can be harmful to the fuel system and
engine.
Octane rating tips
In most parts of North America, you should
use unleaded gasoline with an octane ratingof at least 87 or 91 AKI (Anti-Knock Index)
number. However, you may use unleaded
gasoline with an octane rating as low as 85
AKI (Anti-Knock Index) number in high alti-
tude areas [over 4,000 ft (1,219 m)] such as:
Colorado, Montana, New Mexico, Utah,
Wyoming, northeastern Nevada, southern
Idaho, western South Dakota, western Ne-
braska, and that part of Texas which is
directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated 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 your
dealer correct the condition. Failure to
correct the condition is misuse of the
vehicle, for which NISSAN is not respon-
sible.
