Fuel Requirements - Maserati GranTurismo 2024 Owner's Manual

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.
It is recommended to use unleaded fuel
with no more than 95 AKI. Additives that
further increase the number of octanes
are not admitted.
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 ( : chapter
"Warning and Indicator Lights" in
section "Dashboard Instruments and
Controls) 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".
Technical Specifications
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
illuminate ( : chapter "Warning and
Indicator Lights" in section "Dashboard
Instruments and Controls). Pump labels
should clearly communicate if a fuel
contains greater than 10% Ethanol.
Problems that result from using gasoline
containing Methanol or gasoline
containing more than 10% Ethanol are
