RECOMMENDED FLUIDS/
LUBRICANTS AND CAPACITIES
10-2Technical and consumer information

Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or en-
gine damage. If any of the above symptoms
are encountered, have your vehicle checked.
It is recommended that 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 not a 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, qual-
ity and viscosity engine oil to ensure satisfac-
tory engine life and performance. For addi-
tional information, see "Recommended fluids/
lubricants and capacities" (P. 10-2). 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 or
International Lubricant Standardization andApproval 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.
