technical data NISSAN ALTIMA 2002 L31 / 3.G Owners Manual

FUEL RECOMMENDATION
For 2.5L engine
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) (Research octane number 91).
For 3.5L engine
Use 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
cUsing a fuel other than that specified
could adversely affect the emission
control system, and may also affect
warranty coverage.
cUnder no circumstances should a
leaded gasoline be used since this
will damage the three way catalyst.
Reformulated gasoline
Some fuel suppliers are now producing re-
formulated gasolines. These gasolines are
specially designed to reduce vehicle emis-
sions. NISSAN supports efforts towards
cleaner air and suggests that you use refor-
mulated gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and
methanol with or without advertising their
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
NISSAN vehicles.
