ENGINE OIL AND OIL FILTER RE-COMMENDATIONSelecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTSearlier 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
American Petroleum Institute (API) certifi-
cation or International Lubricant Standar-
dization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification mark
onthe frontof the container. Oils which do
not have the specified quality label should
not be used as they could cause engine
damage.
Oil additives
INFINITIdoes not recommend the use of oil
additives.The use of an oil additive is not
necessarywhen 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
changeswith temperature. Because of this,
it is important 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 recommended
could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine INFINITI oil filter. When
replacing, use the genuine 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. Oil and
filterother than the specified quality, or oil
and filter change intervals longer than
recommended could reduce engine life.
Damage to engines caused by improper
maintenance or use of incorrect oil and
filterquality and/or viscosity is not covered
by the new INFINITI vehicle limited warran-
ties.
