Reformulated gasoline
Many areas of the country require the use of
cleaner burning fuel referred to as "Reformu-
lated Gasoline".
Reformulated gasoline contains oxygenates
and is specially blended to reduce vehicle
emissions and improve air quality.
Mitsubishi Motors Corporation strongly sup-
ports the use of reformulated gasoline. Prop-
erly blended reformulated gasoline has no
adverse effect on vehicle performance or the
durability of engine and fuel system.
MMT (methylcyclopentadienyl
manganese tricarbonyl)
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 performance, and cause the
malfunction indicator on your instrument
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 sat-
isfy California's low-emission regulations
based on clean-burning low-sulfur gasoline.
Gasoline sold in parts of the country other
than California is allowed to have a higher
sulfur content. Using such gasoline could
adversely affect the vehicle's catalytic con-
verter and cause the engine malfunction indi-
cator ("SERVICE ENGINE SOON" or
"Check engine light") to come on. Illumina-
tion of this indicator while you are using
high-sulfur gasoline 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 gas-
oline to determine whether the problem is
fuel-related.
Fuel selection
NOTE
Poor-quality gasoline can cause problems
such as poor starting, stalling during idling,
abnormal engine noise, and poor accelera-
tion. If you experience any of these prob-
lems, try using a different brand of gasoline.
If the engine malfunction indicator ("SER-
VICE ENGINE SOON" or "Check engine
light") flashes, have the vehicle inspected as
soon as possible by the nearest authorized
Mitsubishi Motors dealer or a repair facility
of your choice.
Repeatedly driving short distances at low
speeds can cause deposits to form in the fuel
system and engine, resulting in poor starting
and poor acceleration. If these problems
occur, you are advised to add a detergent
additive to the gasoline when you refuel the
vehicle. The additive will remove the depos-
its, thereby returning the engine to a normal
condition. Be sure to use a Mitsubishi
Motors Genuine cleaning additive. Using an
unsuitable additive could make the engine
malfunction. For details, please contact the
nearest authorized Mitsubishi Motors dealer.
