Incorrect ignition timing results in knocking,
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 at a NISSAN dealer or other
competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating 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
RECOMMENDATION
Selecting the correct oil
It is essential to chose the correct quality
and viscosity oil to ensure satisfactory en-
gine life and performance. Nissan recom-
mends the use of a low friction oil (energy
conserving oil) in order to improve fuel
economy and conserve energy. Oils which
do not have the specified quality label
should not be used as they could cause
engine damage.Only those engine oils with the American
Petroleum Institute (API) CERTIFICATION
MARK on the front of the container should
be used. This type of oil supersedes the
existing API SG or SH and Energy Conserv-
ing II categories.
If you cannot find engine oil with the CER-
TIFICATION MARK, an API SG or SH and
Energy Conserving II oil with API Service
Symbol may be used. An oil with a single
designation SG or SH, or in combination
with other categories (for example, SG/CC
or SG/CD) may also be used if one with the
