2020 NISSAN ALTIMA service

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. ∙
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 co-
solvents and corrosion inhibitors,
such methanol blends may cause fuel
system damage and/or vehicle per-
formance problems. At this time, suf-
ficient data is not available 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.
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 de-
tails.
Technical and consumer information10-5

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
∙ 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 HFO-1234yf (R-1234yf ) and
NISSAN A/C system oil Type PAG
(VC100YF oil) or the exact equivalents.
CAUTION
The use of any other refrigerant or oil
will cause severe damage to the air con-
ditioning system and will require the re-
placement of all air conditioner system
components.
The refrigerant HFO-1234yf (R-1234yf ) in
your NISSAN vehicle does not harm the
earth’s ozone layer. Although this refriger-
ant does not affect the earth’s atmo-
sphere, certain government regulations re-
quire the recovery and recycling of any
refrigerant during automotive air condi-
tioner system service. Air conditioner sys-
tem should only be serviced by trained and
certified technicians to ensure proper and
safe operation (SAE J2845). A NISSAN dealer
has the trained technicians and equip-
ment needed to recover and recycle your
air conditioner system refrigerant. Only
new and SAEJ2842 certified evaporator(s)
shall be used as replacement parts. A damaged or leaking air conditioning
evaporator shall never be repaired or re-
placed with one removed from a used or
salvaged vehicle. To replace a damaged or
leaking evaporator, use only new and SAE
J2842 certified evaporator(s). It is recom-
mended that you visit a NISSAN dealer
when servicing your air conditioner sys-
tem.
10-8Technical and consumer information

Do not tow a trailer with your vehicle.
FLAT TOWING
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when
towing a vehicle behind a recreational ve-
hicle, such as a motor home.
CAUTION
∙ Failure to follow these guidelines canresult in severe transmission damage.
∙ Whenever flat towing your vehicle, al- ways tow forward, never backward.
∙ Never tow your front wheel drive ve- hicle with the front tires on the
ground. Doing so may cause serious
and expensive damage to the
powertrain.
∙ DO NOT tow any continuously variable transmission vehicle with all four
wheels on the ground (flat towing).
Doing so WILL DAMAGE internal trans-
mission parts due to lack of transmis-
sion lubrication. ∙ For emergency towing procedures re-
fer to “Towing recommended by
NISSAN” in the “In case of emergency ”
section of this manual.
Continuously Variable
Transmission (CVT)
To tow a vehicle equipped with a CVT, an
appropriate vehicle dolly MUSTbe placed
under the towed vehicle’s drive wheels.
Always follow the dolly manufacturer’s
recommendations when using their prod-
uct. DOT (Department of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
