2020 INFINITI QX50 oil temperature

To help ensure smooth, safe and economical
driving, INFINITI provides two maintenance
schedules that may be used, depending upon
the conditions in which you usually drive.
These schedules contain both distance and
time intervals, up to 90,000 miles
(144,000 km)/144 months. For most
people, the odometer reading will indicate
when service is needed. However, if you drive
very little, your vehicle should be serviced at
the regular time intervals shown in the sched-
ule.
After 90,000 miles (144,000 km)/144 months,
continue maintenance at the same mileage/time
intervals.
ADDITIONAL MAINTENANCE
ITEMS FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe op-
erating conditionsshould be performed on
vehicles that are driven under especially de-
manding conditions. Additional maintenance
items should be performed if you primarily
operate your vehicle under the following con-
ditions:
∙ Repeated short trips of less than 5 miles (8 km). ∙ Repeated short trips of less than 10 miles
(16 km) with outside temperatures re-
maining below freezing.
∙ Operating in hot weather in stop-and-go “rush hour” traffic.
∙ Extensive idling and/or low speed driving for long distances, such as police, taxi or
door-to-door delivery use.
∙ Driving in dusty conditions.
∙ Driving on rough, muddy or salt spread roads.
∙ Towing a trailer, using a camper or using a car-top carrier.
OIL CONTROL SYSTEM
Your vehicle is equipped with oil control sys-
tem. It calculates engine oil and filter change
intervals based on driving conditions. Driving
in the following severe conditions will shorten
the engine oil and filter change interval.

ConditionsDriving Scene Display timing
Light ∙ Freeway driving
∙ City driving (flat/moderate hills)
∙ No towing or heavy loads
∙ No extended engine idling Normal
Extreme ∙ Repeated short trips of less than 5 miles (8 km).
∙ Repeated short trips of less than 10 miles (16 km) with outside temperatures remaining below
freezing.
∙ Operating in hot weather in stop-and-go “rush hour” traffic.
∙ Extensive idling and/or low speed driving for long distances, such as police, taxi or door-to-
door delivery use.
∙ Towing a trailer or caravan, or using a car-top carrier.
∙ Driving with frequent use of braking or in mountainous areas.
∙ Sustained high speed driving. Early
CAUTION
∙ If the oil replacement indicator is dis-
played, change the engine oil within two
weeks or less than 500 miles (800 km).
∙ Operating your vehicle with deteriorated oil can damage the engine.
∙ If your oil replacement indicator resets prematurely or becomes inoperative,
please change the oil within six months or
3,750 miles (6,000 km) from your last oil
change.

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, refer to "Recom-
mended fluids/lubricants and capacities" in
this section. 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 ve-
hicle.
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 on maintenance
schedules, refer to the “Maintenance and
schedules” section of this manual.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refrigerant
HFC-134a (R-134a) and the oil, Genuine
NISSAN A/C System Oil Type ND-OIL8 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 HFC-134a (R-134a) in your
INFINITI vehicle does not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
government regulations require the recovery
and recycling of any refrigerant during auto-
motive 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.
