RECOMMENDATION
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, see ªCA-
PACITIES AND RECOMMENDED
FUEL/LUBRICANTSº earlier 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) certification or Interna-
tional Lubricant Standardization and Approval
Committee (ILSAC) certification and SAE viscos-
ity standard. These oils have the API certifica-
tion mark on the front of 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 to select the engine oil viscosity 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 NISSAN oil filter. When replac-
ing, use the genuine oil filter or its equivalent
for the reason described in ªChange intervalsº.
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 a
filter other than the specified quality, or exceed-
ing recommended oil and filter change intervals
could reduce engine life. Damage to the engine
caused by improper maintenance or use of
incorrect oil and filter quality and/or viscosity is
not covered by the INFINITI new vehicle limited
warranty.
