fuel additives NISSAN MAXIMA 2003 A33 / 5.G Owners Manual

FUEL RECOMMENDATIONUse unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
For improved vehicle performance,
NISSAN recommends the use of unleaded
premium gasoline with an octane rating of
at least 91 AKI number (Research octane
number 96).
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 refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
NISSAN supports efforts towards cleaner airand suggests that you use reformulated gaso-
line when available.
Gasoline containing oxygenatesSome fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and
methanol with or without advertising their pres-
ence. 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 ser-
vice 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.
IThe fuel should be unleaded and have
an octane rating no lower than that rec-
ommended for unleaded gasoline.
IIf 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%.)
IIf 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 appro-
priate cosolvents and corrosion inhibi-tors. If not properly formulated with ap-
propriate 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 suit-
able for use in NISSAN vehicles.
If any undesirable driveability problems such
as engine stalling and hard hot starting are
experienced after using oxygenate-blend fu-
els, immediately 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.
Aftermarket fuel additivesNISSAN does not recommend the use of any
fuel additives (i.e. fuel injector cleaner, octane
booster, intake valve deposit removers, etc.)
which are sold commercially. Many of these
additives 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 tipsIn most parts of North America, you should use

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oilIt is essential to choose the correct quality, and
viscosity oil to ensure satisfactory engine life
and performance. NISSAN recommends the
use of a low friction oil (energy conserving oil)
in order to improve fuel economy and con-
serve energy. Oils which do not have the
specified quality label should not be used as
they could cause engine damage.
Only those engine oils with the American Pe-
troleum Institute (API) certification mark on thefront of the container should be used. This type
of oil supersedes the existing API SG, SH, or
SJ and Energy ConservingI&IIcategories.
If you cannot find engine oil with the API
certification mark, use an API grade SG/SH,
Energy ConservingI&IIorAPIgrade SJ or
SL, Energy conserving oil. An oil with a single
designation SG or SH, or in combination with
other categories (for example, SG/CC or
SG/CD) may also be used if one with the API
certification mark cannot be found. An ILSAC
grade GF-I, GF-II & GF-III oil can also be used.
NISSAN recommends mineral based oils.
These oils must however, meet the API qualityand SAE viscosity ratings specified for your
vehicle.
Oil additivesNISSAN 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 viscosityThe engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant that the engine oil viscosity be selected
based on the temperatures at which the ve-
hicle will be operated before the next oil
change. The recommended SAE viscosity
number chart shows the recommended oil
viscosities for the expected ambient tempera-
tures. Choosing an oil viscosity other than that
recommended could cause serious engine
damage.Selecting the correct oil filterYour new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When replac-
ing, use the genuine oil filter or its equivalent
for the reason described in change intervals.
