Fuel Requirements
Octane Rating
Maserati engines are designed for
optimum performance on unleaded
premium gasoline with an AKI octane
rating of 91 or above. AKI (Anti Knock
Index) is an average of the Research
Octane Number, RON, and the Motor
Octane Number, MON (RON + MON/2
gives you the AKI).
Unleaded Fuel
Maserati incorporates a catalytic
converter system and you must only
use unleaded gasoline. U.S. and
Canadian regulations require that
pumps delivering unleaded gasoline
be labelled “UNLEADED”. Only these
pumps have nozzles which fit your
vehicle’s fuel filler inlet. It is unlawful
to dispense leaded fuel into a vehicle
labelled “unleaded gasoline only”.
Leaded gasoline damages the catalytic
converter and heated oxygen sensor
system. Repeated use of leaded
gasoline will lessen the effectiveness
of the emission control system and
could result in loss of emission
warranty coverage. State and local
vehicle inspection programs will
make detection of misfueling easier,
possibly resulting in emission test
failure for misfueled vehicles.
WARNING: Some U.S. & Canadian
gasolines use an octane
enhacing additive called Methy-
Cyclopentadienyl Manganese
Tricarbonyl (MMT). If such fuels are
used your Emission Control System
performance may be affected, and
the check engine light located on the
instrument panel/cluster assembly
may illuminate (come ON). If the
check engine light illuminates be sure
to visit your
Authorized Maserati
Dealer for vehicle service.
Gasoline Containing Alcohol &
Ethers (“Oxygenated Fuels”):
Some fuels in the U.S. and/or Canada,
contain “oxygenates” which are
usually alcohols or ethers. In some
locations in the U.S. and/or Canada,
state or local laws require that the
fuel station fuel service pumps be
clearly marked indicating use of
alcohols or ethers. Please be aware
that in some geographic areas fuel
stations may have fueling pumps
that are unmarked. If you are not
sure if the fuel you will be dispensing
into your vehicle contains alcohol or
ethers, ask the fuel service station
operator.
WARNING: Some geographical areas
in the U.S. and/or Canada, require the
use of “oxygenated” fuels to meet
seasonal air quality standards.
- Alcohol - Ethanol: Fuels containing
ONLY up to 10% ethanol by volume
may be used (ethanol may also
be referred to as Ethyl alcohol, or
“Gasohol”.
- Ethers - MTBE: Fuel containing ONLY
up to 15% MTBE may be used.
WARNING: Do not use any gasoline
that contains lead as a knock
inhibitor, and DO NOT use lead
additives. The use of Detergent
gasoline is effective in minimizing fuel
injector and intake valve deposits. The
use of external fuel injector cleaning
systems/fluids is NOT recommended.
