2023 NISSAN ALTIMA octane

FUEL RECOMMENDATION
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
CAUTION
• Only vehicles with the E-85 filler door
label can operate on E-85. Fuel sys-
tem or other damage can occur if
E-85 is used in vehicles that are not
designed to run on E-85.
• Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect
the warranty coverage.
• Under no circumstances should a
leaded gasoline be used, because
this will damage the three-way
catalyst. •
Do not use a fuel containing more
than 15% ethanol in your vehicle. Your
vehicle is not designed to run on a
fuel containing more than 15% etha-
nol. Using a fuel containing more
than 15% ethanol in a vehicle not spe-
cifically designed for a fuel contain-
ing more than 15% ethanol can ad-
versely affect the emission control
devices and systems of the vehicle.
Damage caused by such fuel is not
covered by the NISSAN New Vehicle
Limited Warranty.
• Do not use fuel that contains the oc-
tane booster methylcyclopentadi-
enyl manganese tricarbonyl (MMT).
Using fuel containing MMT may ad-
versely affect vehicle performance
and vehicle emissions. Not all fuel
dispensers are labeled to indicate
MMT content, so you may have to
consult your gasoline retailer for
more details. Note that Federal and
California laws prohibit the use of
MMT in reformulated gasoline. •
U.S. government regulations require
ethanol dispensing pumps to be
identified by a small, square, orange
and black label with the common ab-
breviation or the appropriate per-
centage for that region.Gasoline specifications
NISSAN recommends using gasoline that
meets the World-Wide Fuel Charter (WWFC)
specifications where it is available. Many of
the automobile manufacturers developed
this specification to improve emission con-
trol system and vehicle performance. Ask
your service station manager if the gaso-
line meets the WWFC specifications.
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 re-
formulated gasoline when available.
10-4Technical and consumer information

Gasoline containing oxygenates
Some fuel suppliers sell gasoline contain-
ing oxygenates such as ethanol, Methyl
Tert-butyl Ether (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 can-
not 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 that
recommended for unleaded gasoline.
• If an oxygenate-blend other than
methanol blend is used, it should con-
tain no more than 15% oxygenate. •
If 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 damage
and/or vehicle performance problems.
At this time, sufficient data is not avail-
able to ensure that all methanol blends
are suitable for use in NISSAN vehicles.
If any driveability problems such as engine
stalling and difficult hot-starting are expe-
rienced af ter 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 re-
fueling. Gasoline containing oxygenates
can cause paint damage.
E–15 fuel
E-15 fuel is a mixture of approximately 15%
fuel ethanol and 85% unleaded gasoline.
E-15 can only be used in vehicles designed
to run on E-15 fuel. U.S. government regula-
tions require fuel ethanol dispensing
pumps to be identified with small, square,
orange and black label with the common
abbreviation or the appropriate percent-
age for that region.
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 in your ve-
hicle. U.S. government regulations require
fuel ethanol dispensing pumps to be iden-
tified by a small, square, orange and black
label with the common abbreviation or the
appropriate percentage for that region.
Technical and consumer information10-5

Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting ad-
ditive. NISSAN does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding the emissions control system. Note
that while some fuel pumps label MMT
content, not all do, so you may have to
consult your gasoline retailer for more
details.
Af termarket fuel additives
NISSAN does not recommend the use of
any af termarket fuel additives (for ex-
ample, 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 sol-
vents 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 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, it is recom-
mended that you have a NISSAN dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.
Incorrect ignition timing may result in
spark knock, af ter-run and/or overheating,
which may cause excessive fuel consump-
tion or engine damage. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for servicing.However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not
a cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
10-6Technical and consumer information

When planning to drive your NISSAN ve-
hicle in another country,you should first
find out if the fuel available is suitable for
your vehicle's engine.
Using fuel with an octane rating that is too
low may cause engine damage. All gaso-
line vehicles must be operated with un-
leaded gasoline. Therefore, avoid taking
your vehicle to areas where appropriate
fuel is not available.
When transferring the registration of
your vehicle to another country, state,
province or district, it may be necessary
to modif y the vehicle to meet local laws
and regulations.
The laws and regulations for motor vehicle
emission control and safety standards
vary according to the country, state, prov-
ince or district; therefore, vehicle specifica-
tions may differ.
When any vehicle is to be taken into an-
other country, state, province or district
and registered, its modifications, trans-
portation and registration are the re-
sponsibility of the user. NISSAN is not re-
sponsible for any inconvenience that
may result.
