2019 NISSAN FRONTIER PRO-4X Owners Manual

∙ Do not use a fuel containing morethan 15% ethanol in your vehicle. Your
vehicle is not designed to run on a fuel
containing more than 15% ethanol.
Using a fuel containing more than 15%
ethanol in a vehicle not specifically
designed for a fuel containing more
than 15% ethanol can adversely affect
the emission control devices and sys-
tems 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 methylcyclopentadienyl
manganese tricarbonyl (MMT). Using
fuel containing MMT may adversely
affect vehicle performance and ve-
hicle emissions. Not all fuel dispens-
ers are labeled to indicate MMT con-
tent, so you may have to consult your
gasoline retailer for more details.
Note that Federal and California laws
prohibit the use of MMT in reformu-
lated gasoline. ∙ U.S. government regulations require
ethanol dispensing pumps to be iden-
tified by a small, square, orange and
black label with the common abbre-
viation 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 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.
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
contain no more than 15% oxygenate.
Technical and consumer information10-5

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.
FUEL RECOMMENDATION (for
VQ40DE models)
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).

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, have a
NISSAN dealer correct the condition. Fail-
ure to correct the condition is misuse of
the vehicle, for which NISSAN is not re-
sponsible.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.

FLEXIBLE FUEL VEHICLE (FFV) FUEL
RECOMMENDATION (if so
equipped)
Your vehicle is designed to use (E-85) Fuel
Ethanol, “Regular” unleaded regular gaso-
line or any percentage of the two fuels
combined.
U.S. government regulations require Fuel
Ethanol dispensing pumps to have a
small, square, orange and black label
with the common abbreviation or the
appropriate percentage for that region.

WARNING
∙ Ethanol vapors are extremely flam-mable and could cause serious per-
sonal injury.
∙ Never have any smoking materials lit in or near the vehicle when removing
the fuel filler cap or filling the tank.
∙ Do not use E-85 as a cleaning agent and never use it near an open flame.
Fuel requirements
Your vehicle will operate on both unleaded
regular gasoline with an octane rating of at
least 87 AKI (Anti-Knock Index) number (Re-
search octane number 91), or E-85 fuel, or
any mixture of these two.
For the best starting and vehicle driveabil-
ity results, do not continually switch be-
tween E-85 and unleaded regular gasoline.
If you must switch fuels, NISSAN recom-
mends the following: ∙ do not switch when the fuel gauge indi- cates less than 1/4 full
∙ add more than 5 gallons of fuel
∙ operate the vehicle immediately af ter refueling for a period of at least 5 min-
utes NOTE:
When the ambient temperature is above
90°F (32°C), you may experience hard
starting and rough idle following start
up even if the above recommendations
are followed.
Starting
The characteristics of E-85 fuel make it un-
suitable for use when ambient tempera-
tures fall below 0°F (-18°C). In the range of
0°F (-18°C) to 32°F (0°C), you may experience
an increase in the time it takes for you en-
gine to start, and a deterioration in drivabil-
ity (sags and/or hesitations) until the en-
gine is fully warmed up.
Fuel consumption
Because E-85 fuel contains less energy per
gallon than gasoline, you will experience an
increase in fuel consumption. You can ex-
pect your fuel mileage to decrease by
about 30% compared to gasoline opera-
tion.
Replacement parts
Many components in your Flexible Fuel Ve-
hicle (FFV) are designed to be compatible
with ethanol. Always be sure that your ve-
hicle is serviced with correct ethanol com-
patible parts.

Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter
change intervals depend upon how you
use your vehicle.
Operation under the following conditions
may require more frequent oil and filter
changes:∙ repeated short distance driving at cold outside temperatures
∙ driving in dusty conditions
∙ extensive idling
∙ towing a trailer
∙ stop and go commuting
For additional information, refer to the
“Maintenance and schedules” section of
this manual.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your
NISSAN vehicle must be charged with the
refrigerant HFC-134a (R-134a) and
NISSAN A/C system oil Type R (KLH00-
PAGRO) or the exact equivalents.
