Reformulated Gasoline - Mitsubishi ECLIPSE Owner's Manual

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.
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") 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.
NOTE
Poor-quality gasoline can cause problems such as poor
starting, stalling during idling, abnormal engine noise, and
poor acceleration. If you experience any of these prob-
lems, try using a different brand of gasoline. If the engine
malfunction indicator ("SERVICE ENGINE SOON" or
"CHECK ENGINE") flashes, have the vehicle inspected
as soon as possible by the nearest authorized Mitsubishi
Motors dealer or a repair facility of your choice.
