. If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not
available to ensure that all methanol
blends are suitable for use in INFINITI
vehicles.
If any undesirable driveability problems
such as engine stalling or hard hot starting
are experienced after using oxygenate-
blend fuels, immediately change to a
non-oxygenate fuel or a fuel with a low
blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygenates
can cause paint damage.
E-85 fuel
E-85 fuel is a mixture of approximately
85% fuel ethanol and 15% unleaded
gasoline. E-85 can only be used in a
Flexible Fuel Vehicle (FFV). Do not use E-
85 fuel in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.
Aftermarket fuel additives
INFINITI does not recommend the use of
any aftermarket fuel additives (Example:
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 ac tive solvent 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 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 an INFINITI dealer
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 at an INFINITI 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.
