2023 INFINITI QX50 oil temperature

CAUTION
Oil level should be checked regularly. Oper-
ating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.
CHANGING ENGINE OIL AND OIL
FILTER
For additional information on engine oil and
oil filter change, refer to the instructions out-
lined in this section.
Vehicle set-up
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3.
Turn the engine off and wait for 15 minutes.
4. Raise and support the vehicle using a suit- able floor jack and safety jack stands.
• Place the safety jack stands under the ve- hicle jack-up points.
• A suitable adapter should be attached to the jack stand saddle.
CAUTION
Make sure the correct lifting and support
points are used to avoid vehicle damage.

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.
How driving conditions affect OCS display
timing
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 deterio-
rated 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.
9-8Maintenance and schedules

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.
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 en-
gine oil when it was built. You do not have to
change the oil before the first recommended
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 refriger-
ant HFO-1234yf (R-1234yf) and the oil,
Genuine NISSAN A/C System Oil Type PAG
(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. Air
conditioner system should only be serviced by
trained and certified technicians to ensure
proper and safe operation (SAE J2845). An
INFINITI retailer has the trained technicians
and equipment needed to recover and recycle
your air conditioner system refrigerant. Only
new and SAEJ2842 certified evaporator(s)
shall be used as replacement parts.
