Timing NISSAN SENTRA 1996 B14 / 4.G Owners Manual

an octane rating as low as 85 AKI (Anti-
Knock Index) in high altitude areas (over
4,000 ft [1,219 m]) such as: Colorado, Mon-
tana, New Mexico, Utah, Wyoming, north-
eastern Nevada, southern Idaho, western
South Dakota, western Nebraska, and that
part of Texas which is directly south of New
Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy ``spark knock.'' (``Spark
knock'' is a metallic rapping noise.) If
severe, this can lead to engine damage. If
you detect a persistent heavy spark
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady
speed on level roads, have your dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.
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.
