2021 NISSAN ARMADA octane

10-4Technical and consumer information
FUEL INFORMATION
VK56VD engine
NISSAN recommends the use of unleaded
premium gasoline with an octane rating
of at least 91 AKI (Anti-Knock Index)
number (Research octane number 96).
If unleaded premium gasoline is not
available, you may use unleaded regular
gasoline with an octane rating of at least
87 AKI number (Research octane number
91), but you may notice a decrease in
performance.
CAUTION
.Using a fuel other than that spe-
cified could adversely affect the
emission control system, and
may also affect warranty cover-
age.
. Under no circumstances should a
leaded gasoline be used, because
this will damage the three-way
catalyst.
. Do not use E-15 or E-85 fuel in
your vehicle. Your vehicle is not
designed to run on E-15 or E-85
fuel. Using E-15 or E-85 fuel in a
vehicle not specifically designed
for E-15 or E-85 fuel can adversely affect the emission control de-
vices 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
octane booster methylcyclopen-
tadienyl manganese tricarbonyl
(MMT). Using fuel containing
MMT may adversely affect vehicle
performance and vehicle emis-
sions. 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 re-
quire ethanol dispensing pumps
to be identified by a small,
square, orange and black label
with the common abbreviation or
the appropriate percentage for
that region.
Gasoline specifications
NISSAN recommends using gasoline that
meets the World-Wide Fuel Charter
(WWFC) specifications where it is avail-
able. Many of the automobile manufac-
turers developed this specification to
improve emission system and vehicle
performance. Ask your service station
manager if the gasoline meets the
World-Wide Fuel Charter (WWFC) specifi-
cations.
Reformulated gasoline
Some fuel suppliers are now producing
reformulated gasolines. These gasolines
are specially designed to reduce vehicle
emissions. NISSAN supports efforts to-
wards cleaner air and suggests that you
use reformulated gasoline when avail-
able.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline contain-
ing oxygenates such as ethanol, MTBE
and methanol with or without advertising
their presence. NISSAN does not recom-
mend the use of fuels of which the
oxygenate content and the fuel compat-
ibility 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 sys-
tem damage.
.The fuel should be unleaded and
have an octane rating no lower than
that recommended for unleaded
gasoline.
. If an oxygenate-blend, excepting a
methanol blend, is used, it should
contain no more than 10% oxyge-
nate. (MTBE may, however, be added
up to 15%.)
. E-15 fuel contains more than 10%
oxygenate. E-15 fuel will adversely
affect the emission control devices
and systems of the vehicle and
should not be used. Damage caused
by such fuel is not covered by the
NISSAN new vehicle limited war-
ranty.
. 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 corrosion inhibitors. If not prop-
erly formulated 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 available to
ensure that all methanol blends are
suitable for use in NISSAN vehicles.
If any undesirable driveability problems
such as engine stalling or hard hot
starting are experienced after using oxy-
genate-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 oxyge-
nates can cause paint damage.
E-15 fuel
E-15 fuel is a mixture of approximately
15% fuel ethanol and 85% unleaded gaso-
line. E-15 can only be used in vehicles
designed to run on E-15 fuel. Do not use E-
15 in your vehicle. U.S. government reg-
ulations require fuel ethanol dispensing
pumps to be identified with small, square,
orange and black label with the common
abbreviation or the appropriate percen-
tage for that region.
E-85 fuel
E-85 fuel is a mixture of approximately
85% fuel ethanol and 15% unleaded gaso-
line. E-85 can only be used in a Flexible
Fuel Vehicle (FFV). Do not use E-85 fuel in
your vehicle. U.S. government regulations
require fuel ethanol dispensing pumps to be identified by a small, square, orange
and black label with the common abbre-
viation or the appropriate percentage for
that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting
additive. NISSAN does not recommend
the use of fuel containing MMT. Such fuel
may adversely affect vehicle perfor-
mance, including 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.
Aftermarket fuel additives
NISSAN does not recommend the use of
any aftermarket fuel additives (Example:
fuel injector cleaner, octane booster, in-
take valve deposit removers, etc.) which
are sold commercially. Many of these
additives intended for gum, varnish or
deposit removal may contain active sol-
vent 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 above
can cause persistent, heavy spark
knock. (Spark knock is a metallic rap-
ping noise.) If severe, this can lead to
engine damage. If you detect a persis-
tent 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 recommended you have a
NISSAN dealer correct the condition.
Failure to correct the condition is mis-
use of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in
knocking, after-run or overheating. This
in turn may cause excessive fuel con-
sumption or damage to the engine. If any
of the above symptoms are encountered,
have your vehicle checked. It is recom-
mended 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
no cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time under
heavy engine load.

ENGINE OIL AND OIL FILTER RE-
COMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see “Capacities and recommended fluids/
lubricants” (P.10-2). NISSAN recommends
the use of an energy conserving oil in
order to improve fuel economy.
Select only engine oils that meet the
American Petroleum Institute (API) certifi-
cation or International Lubricant Standar-dization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification mark
on the front of the container. Oils which
do not have the specified quality label
should not be used as they could cause
engine damage.
Oil additives
NISSAN 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 fol-
lowed.
Oil which may contain foreign matter or
has been previously used should not be
used.

If you plan to travel in another country,
you should first find out if the fuel
available is suitable for your vehicle’s
engine.
Using fuel with too low an octane rating
may cause engine damage. All gasoline
vehicles must be operated with unleaded
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 modify the vehicle to meet local laws
and regulations.
The laws and regulations for motor
vehicle emission control and safety stan-
dards vary according to the country,
state, province or district; therefore, vehi-
cle specifications may differ.
When any vehicle is to be taken into
another country, state, province or dis-
trict and registered, its modifications,
transportation, and registration are the
responsibility of the user. NISSAN is not
responsible for any inconvenience that
may result.
