Fuel Requirements The engines are designed to meet all
environmental regulations and provide
excellent fuel economy and
performance when using unleaded
premium gasoline with an AKI octane
rating of 91 or above. AKI (Anti Knock
Index) is an average on the Research
Octane Number, RON, and the Motor
Octane Number, MON (RON + MON/2
gives you the AKI).
For vehicle top performance, use
unleaded premium gasoline with no
less than 93 minimum AKI octane
rating.
Poor quality gasoline can cause
problems such as hard starting,
stalling, and hesitations. If you
experience these symptoms, try
another brand of gasoline before
considering service for the vehicle at
an Authorized Maserati Dealer .
Besides using unleaded gasoline with
the proper octane rating, gasoline that
contain detergents, anti-corrosion and
stability additives are recommended.
Using gasoline that have these
additives may help improve fuel
economy, reduce emissions, and
maintain vehicle performance. CAUTION!
• Maserati strongly recommends the
use of Premium unleaded fuel ONLY.
Use of lesser grade fuel (other than
Premium) will lead to reduced
engine performance, and poor fuel
economy and can lead to the
Malfunction Indicator Light
illuminating on the instrument
cluster. Continued use of lesser grade
fuel (other than Premium fuel) can
lead to engine misfire problems and
possible catalytic converter damage.
• The anti-pollution devices of the
vehicle require unleaded fuel to be
used at all times. Under no
circumstance, not even in an
emergency, should leaded fuel be
supplied to the fuel tank, not even a
minimum quantity. This would
irreparably damage the catalytic
converters. An inefficient catalytic
converter results in noxious exhaust
emissions which damage the
environment.
Reformulated Gasoline Many areas of the country require the
use of cleaner burning gasoline,
referred to as “Reformulated Gasoline”. Reformulated gasoline
contains oxygenates and are
specifically blended to reduce vehicle
emissions and improve air quality.
Maserati supports the use of
reformulated gasoline. Properly
blended reformulated gasoline will
provide excellent performance and
durability of engine and fuel system
components.
Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded
gasoline with oxygenates such as
Ethanol. Fuels blended with
oxygenates may be used in your
vehicle.
CAUTION!
DO NOT use gasoline containing
Methanol or gasoline containing more
than 10% Ethanol. Use of these blends
may result in starting and driveability
problems, damage critical fuel system
components, cause emissions to exceed
the applicable standard, and/or cause
the Malfunction Indicator Light
to
illuminate (see “Instrument Cluster” in
section “Dashboard Instruments and
Controls”. Pump labels should clearly
communicate if a fuel contains greaterDriving

than 10% Ethanol.
Problems that result from using
gasoline containing Methanol or
gasoline containing more than 10%
Ethanol are not the responsibility of
Maserati and may not be covered
under warranty.
MMT in Gasoline MMT (Methylcyclopentadienyl
Manganese Tricarbonyl) is a
manganese containing metallic
additive that is blended into some
gasoline to increase octane.
Gasoline blended with MMT provides
no performance advantage beyond
gasoline of the same octane number
without MMT.
Maserati recommends gasoline
without MMT to be used in your
vehicle. The MMT content of gasoline
may not be indicated on the gasoline
pump; therefore, you should ask the
gasoline station operator whether or
not the gasoline contains MMT.
It is even more important to look for
gasoline without MMT in Canada,
because MMT can be used at levels
higher than those allowed in the
United States. MMT is prohibited in
Federal and California reformulated
gasoline. Materials Added to Fuel All gasoline sold in the United States is
required to contain effective
detergent additives. Use of additional
detergents or other additives is not
needed under normal conditions and
they would result in additional cost.
Therefore, you should not have to add
anything to the fuel.
Fuel System Warnings WARNING!
Follow these guidelines to maintain
your vehicle's performance:
• The use of leaded gasoline is
prohibited by Federal and Provincial
law. Using leaded gasoline can
impair engine performance and
damage the emissions control
system.
• The use of fuel additives, which are
now being sold as octane enhancers,
is not recommended. Most of these
products contain high
concentrations of methanol. Fuel
system damage or vehicle
performance problems resulting
from the use of such fuels or
additives is not the responsibility of Maserati.
NOTE:
Intentional
tampering with
the
emissions control system can result in
civil penalties civil penalties and could
void the vehicle warranty.
Carbon Monoxide Warnings WARNING!
Carbon monoxide (CO) in exhaust
gases is deadly. Follow the
precautions below to prevent carbon
monoxide poisoning:
• Do not inhale exhaust gases. They
contain carbon monoxide, a
colorless and odorless gas, which
can kill. Never run the engine in a
closed area, such as a garage, and
never sit in a parked vehicle with
the engine running for an extended
period. If the vehicle is stopped in
an open area with the engine
running for more than a short
period, adjust the ventilation system
to force fresh, outside air into the
vehicle.
• Guard against carbon monoxide
