Fuel Selection; Gasoline Detergent Additives; Octane Requirement; Oxygenated Gasoline - Mitsubishi Galant Owner's Manual

General information

Fuel selection

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.
WARNING
!
1
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.

Gasoline detergent additives

In 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 requirement

Your vehicle is designed to operate on unleaded gasoline hav-
N00301000794
ing a minimum octane number of 87 [(MON+RON)/2], or 91
RON.

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 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 on the durabil-
ity of the engine and fuel system.
