10-6 Technical and consumer information
Aftermarket fuel additives
V37-D-121025-0241A1D6-50DD-4735-AB1B-1BF6D3FF4840
INFINITI does not recommend the use of
any aftermarket fuel additives (Example:
fuel injector cleaner, octane booster, in-
take valve deposit removers, etc.) which
are sold commercially. Many of these
additives intended for gum, varnish or
deposit removal may contain active solvent
or similar ingredients that can be harmful
to the fuel system and engine.
Octane rating tips
V37-D-121025-0C94128B-44FC-407D-B5D4-1374AB611F20
Using unleaded gasoline with an octane
rating lower than recommended 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, it is recommended you have
an INFINITI retailer correct the condition.
Failure to correct the condition is misuse of
the vehicle, for which INFINITI is not
responsible.
Incorrect ignition timing will result in
knocking, after-run 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 vehicle checked. It is recommended
you visit an INFINITI retailer for servicing.
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.
