Your vehicle is designed to use unleaded gasoline only. It is
equipped with a fuel filler tube especially designed to accept
only a small diameter unleaded gasoline dispensing nozzle. Gasoline detergent additivesIn the United States, fuel suppliers are required by law to add
detergents to their gasoline to minimize fuel-injector fouling
and minimize intake-valve deposits. Detergent gasoline helps
keep your engine in tune and your emission-control system
working properly.
Octane requirementExcept for vehicles equipped with turbochargerYour vehicle is designed to operate on unleaded gasoline hav-
ing a minimum octane number of 87 [(MON+RON)/2], or 91
RON.Vehicles equipped with turbochargerYour vehicle is designed to operate on premium grade
unleaded gasoline having a minimum octane rating of 93
[(MON+RON)/2] or higher for optimum performance. In case
premium grade unleaded gasoline 93 [(MON+RON)/2] is not
available, unleaded gasoline rating of 91 [(MON+RON)/2] can
be used. However, the performance level is reduced.
In order to maintain exhaust system durability, premium
unleaded gasoline having an octane rating of at least 91
[(MON+RON)/2] must be used.
If the premium grade unleaded gasoline rating of 91
[(MON+RON)/2] or higher is not available on journey, etc.,
regular unleaded gasoline having an octane rating of 87
[(MON+RON)/2] can be used temporarily as an emergency
measure.

!
Gasoline is highly flammable and explosive. You
could be burned, seriously injured or killed when
handling it. Whenever you refuel your vehicle, stop
the engine and keep flames, sparks, and smoking
materials away from the vehicle. Always handle fuel
in well-ventilated outdoor areas.
CAUTION
!
Using leaded gasoline in your vehicle will damage
the engine, catalytic converter, and the oxygen sen-
sors. Also, using leaded gasoline is illegal, and will
void your warranty coverage of the engine, catalytic
converter, and oxygen sensors.

Oxygenated gasoline Gasoline sold at some service stations contains oxygenates
such as ethanol and MTBE, although the oxygenates may not
be identified by those names. Oxygenates are required in some
areas of the country. Such fuel can be used in your vehicle.Ethanol (Gasohol) A mixture of up to 10 % ethanol (grain alcohol) and 90 %
unleaded gasoline may be used in your vehicle, provided the
octane number is at least as high as that recommended for
unleaded gasoline. Methanol Do not operate your vehicle on gasoline containing methanol
(wood alcohol). Using this type of alcohol could adversely
affect the vehicle’s performance and damage critical parts of
the vehicle’s fuel system.Reformulated gasoline Many areas of the country require the use of cleaner burning
fuel referred to as “Reformulated Gasoline”.
Reformulated gasoline contains oxygenates and is specially
blended to reduce vehicle emissions and improve air quality.
Mitsubishi Motors Corporation strongly supports the use of
reformulated gasoline. Properly blended reformulated gasoline
has no adverse effect on vehicle performance or the durability
of the engine and fuel system.
MMT (methylcyclopentadienyl manganese tri-
carbonyl)MMT is a manganese-containing metallic additive that is
blended into some gasolines to increase the octane number.
Mitsubishi Motors Corporation recommends using gasolines
without MMT.
Use of gasolines blended with MMT may adversely affect per-
formance, and cause the malfunction indicator on your instru-
ment panel to come on. If this happens, contact an authorized
Mitsubishi Motors dealer or a repair facility of your choice for
assistance.Sulfur in gasoline Your vehicle may have been designed to satisfy California’s
low-emission regulations based on clean-burning low-sulfur
gasoline. Gasoline sold in parts of the country other than Cali-
fornia is allowed to have a higher sulfur content. Using such
gasoline could adversely affect the vehicle’s catalytic converter
and cause the engine malfunction indicator (“SERVICE
ENGINE SOON” or “Check engine light”) to come on. Illumi-
nation of this indicator while you are using high-sulfur gaso-
line does not necessarily mean the vehicle’s emission-control
system is malfunctioning. Your authorized Mitsubishi Motors
dealer may suggest you try using a different, lower-sulfur
brand of unleaded gasoline to determine whether the problem
is fuel-related.
