engine overheat NISSAN SENTRA 2018 Owner´s Manual

Af termarket fuel additives
NISSAN does not recommend the use of
any af termarket fuel additives (for ex-
ample, fuel injector cleaner, octane
booster, intake valve deposit removers,
etc.) which are sold commercially. Many of
these additives intended for gum, varnish
or deposit removal may contain active sol-
vents or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended 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, it is recom-
mended that you have a NISSAN dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.Incorrect ignition timing may result in
spark knock, af ter-run and/or overheating,
which may cause excessive fuel consump-
tion or engine damage. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating 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.
