l
For petrol-powered vehicles,
the use of lea-
ded fuel can result in serious damage to
the engine and catalytic converter. Do not
use leaded fuel.
l Diesel-powered vehicles to comply with
the Euro 4 and Euro 5 regulation are de-
signed to use only diesel fuel that meets
the EN 590 standard.
Use of any other type of diesel fuel would
adversely affect the engine’s performance
and durability. CAUTION
l
For diesel-powered vehicles,
if proper
“winter” fuel is not used in winter, the die-
sel preheat indication lamp may blink
and the engine speed may not rise above
the idling speed because of fuel freezing.
In this case, keep the engine idling for
about ten minutes, then turn off the igni-
tion switch and immediately turn it on
again to confirm that the diesel preheat in-
dication lamp is off. (Refer to “Diesel pre-
heat indication lamp” on page 3-08)
NOTE l It is advisable to sufficiently warm up the en-
gine
after starting

it when the outside temper-
ature is below zero °C.
l Due to the separation of paraffin, the fluidity
of the fuel decreases considerably as the tem-
perature falls. Because of this fact there are
two kinds of fuel: “summer” and “winter”.
This must be considered in winter use.
Select either of the two kinds of fuel in ac-
cordance with ambient temperature.
Above -5 °C: “Summer” diesel
Below -5 °C: “Winter” diesel
When travelling abroad, find out in advance
about the fuels served in local service stations.
l Petrol-powered vehicles have the knock con-
trol system so that you can use unleaded pet-
rol 91 RON as an emergent measure in case
unleaded petrol 95 RON or higher is not avail-
able on journey, etc. In such a case, you
don’t need to adjust the engine specially.
In case of using unleaded petrol 91 RON, the
engine performance level is reduced. l
In petrol-powered
vehicles,
repeatedly driv-
ing short distances at low speeds can cause
deposits to form in the fuel system and en-
gine, resulting in poor starting and poor accel-
eration.
If these problems occur, you are advised to
add a detergent additive to the gasoline when
you refuel the vehicle. The additive will re-
move the deposits, thereby returning the en-
gine to a normal condition. Be sure to use a
genuine MITSUBISHI FUEL SYSTEM
CLEANER. Using an unsuitable additive
could make the engine malfunction.
For details, please contact a MITSUBISHI
MOTORS Authorized Service Point.
l Poor quality petrol can cause problems such
as difficult starting, stalling, engine noise
and hesitation. If you experience these prob-
lems, try another brand and/or grade of petrol.
If the check engine warning lamp flashes,
have the system checked as soon as possible
at a MITSUBISHI MOTORS Authorized
Service Point.
l In diesel-powered vehicles, poor-quality die-
sel fuel can cause deposits form in the injec-
tor, resulting in black smoke and rough idling.
If these problems occur, you are advised to
add a cleaning additive to the diesel fuel
when you refuel the vehicle. The additive
will break up and remove the deposits, there-
by returning the engine to a normal condition.
Be sure to use a genuine MITSUBISHI DIE-
SEL FUEL SYSTEM CLEANER. Using an
unsuitable additive could make the engine
malfunction. For details, please contact a
MITSUBISHI MOTORS Authorized Service
Point. General information
