oil viscosity INFINITI QX30 2018 Owner's Manual

•Keep your engine tuned up.
•Follow the recommended scheduled
maintenance.
•Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
•Keep all the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
•Use the recommended viscosity engine oil.
For additional information, see "Recom-
mended fluids/lubricants and capacities"
WARNING
•Do not drive beyond the performance
capability of the tires, even with 4WD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
•For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to any
drive or reverse position with the engine
running. Doing so may result in drive-
train damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
•Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) or
similar equipment even if the other two
wheels are raised off the ground. Make
sure that you inform the test facility
personnel that your vehicle is equipped
with 4WD before it is placed on a dyna-
mometer. Using the wrong test equip-
ment may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage or
personal injury.
•When a wheel is off the ground due to an
uneven surface, do not spin the wheel
excessively.

10-2Technical information

Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel in-
jector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold com-
mercially. Many of these additives intended
for gum, varnish or deposit removal may con-
tain active solvent or similar ingredients that
can be harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rat-
ing lower than recommended above 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, it is recom-
mended you have an INFINITI retailer cor-
rect the condition. Failure to correct the con-
dition is misuse of the vehicle, for which
INFINITI is not responsible.
Incorrect ignition timing will result in knock-
ing, after-run and/or overheating. This in turn
may cause excessive fuel consumption or
damage to the engine. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended you visit an
INFINITI retailer.However, now and then you may notice light
spark knock for a short time while accelerat-
ing or driving up hills. This is no cause for
concern, because you get the greatest fuel
benefit when there is light spark knock for a
short time under heavy engine load.
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"
earlier in this section.
Select only engine oils that meet the MB229.5
specification and SAE viscosity standard. These
oils have the MB229.5 specification label on the
container. Oils which do not have the specified
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 that the engine oil viscosity be selected
based on the temperatures at which the vehicle
will be operated before the next oil change.
Choosing an oil viscosity other than that recom-
mended could cause serious engine damage.

Selecting the correct oil filter
Your new vehicle is equipped with a high—
quality genuine INFINITI oil filter. When re-
placing, it is recommended you use the genu-
ine 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. Damage to
engines caused by improper maintenance or
use of incorrect oil and filter quality and/or
viscosity is not covered by the new 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
outside temperatures
•Driving in dusty conditions
•Extensive idling
•Stop and go “rush hour” traffic
Refer to the “INFINITI Service and Mainte-
nance Guide” for the maintenance schedule.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system of your vehicle
must be charged with the refrigerant HFC-
134a and the lubricant INFINITI A/C System
Oil Type S or the exact equivalents.
CAUTION
The use of any other refrigerant or oil may
cause severe damage to the air condition-
ing system and will require the replacement
of all air conditioner system components.
The refrigerant HFC-134a in your vehicle will
not harm the Earth’s ozone layer. However, it
may contribute in a small part to the global
warming effect.
Certain 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.
