fuel consumption NISSAN QUEST 1997 V40 / 1.G Owners Manual

Incorrect ignition timing may result in spark
knock, after-run, and/or overheating, which
may cause excessive fuel consumption or
engine damage. If any of the above symp-
toms are encountered, have your vehicle
checked at an authorized 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 engine oil with the
correct quality and viscosity to ensure sat-

SAN recommends the use of a low friction
oil (energy conserving oil) in order to im-
prove 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

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, an
Energy Conserving II oil with the API Ser-
vice Symbol may be used. An oil with a
single designation SG or SH, or in combi-
nation with other categories (for example,
SG/CC or SG/CD) may also be used if one
