(1) If towing a trailer, using a camper or a
car-top carrier, or driving on rough or muddy
roads, change (not just inspect) oil every
20,000 miles (32,000 km) or 24 months.
(2) If the oil replacement indicator is dis-
played, change the engine oil and filter within
two weeks or less than 500 miles (800 km).
(3) If operating mainly in dusty conditions,
more frequent maintenance may be required.
* Maintenance items and intervals with“*”
are recommended by NISSAN for reliable ve-
hicle operation. The owner need not perform
such maintenance in order to maintain the
emission warranty or manufacturer recall li-
ability. Other maintenance items and inter-
vals are required.

ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality and viscosity engine oil to ensure sat-
isfactory engine life and performance. For
additional information, see "Recommended
fluids/lubricants and capacities" (P. 10-2).
INFINITI recommends the use of an energy
conserving oil in order to improve fuel
economy.
Select only engine oils that meet the Ameri-
can Petroleum Institute (API) certification orInternational Lubricant Standardization 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 speci-
fied quality label should not be used as they
could cause engine damage.
Oil additives
INFINITI 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 followed.
Oil which may contain foreign matter or has
been previously used should not be used.
Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant to select the engine oil viscosity based on
the temperatures at which the vehicle will be
operated before the next oil change. Choos-
ing an oil viscosity other than that recom-
mended could cause serious engine damage.
Selecting the correct oil filter
Your new INFINITI vehicle is equipped with a
high-quality Genuine NISSAN oil filter. When
replacing, use a Genuine NISSAN oil filter or
its equivalent for the reason described in
“Change intervals”.
Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Using engine oil and
filters that are not of the specified quality, or
exceeding recommended oil and filter change
intervals could reduce engine life.
LTI2061
10-6Technical and consumer information

CAUTION
Damage to engine caused by improper
maintenance or use of incorrect oil and fil-
ter quality and/or viscosity is not covered
by the INFINITI New Vehicle Limited
Warranty.
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 out- side temperatures
• driving in dusty conditions
• extensive idling
• towing a trailer
• stop and go commuting
For additional information on maintenance
schedules, see “Maintenance and schedules”
(P. 9-2).AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refrigerant
HFO-1234yf (R-1234yf) and the oil, Genu-
ine NISSAN A/C System Oil Type ND-OIL12
or the exact equivalents.
CAUTION
The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replacement
of all air conditioner system components.
The refrigerant HFO-1234yf (R-1234yf) in
your INFINITI vehicle does not harm the
earth's ozone layer. Although this refrigerant
does not affect the earth's atmosphere, cer-
tain government regulations require the re-
covery and recycling of any refrigerant during
automotive air conditioner system service. An
INFINITI retailer has the trained technicians
and equipment needed to recover and recycle
your air conditioner system refrigerant.
It is recommended that you visit an INFINITI
retailer when servicing your air conditioner
system.
