Reformulated Gasoline - Mitsubishi 2010 RVR Owner's Manual

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 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.
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 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 addi-
tive to the gasoline when you refuel the vehicle. The addi-
tive will remove the deposits, thereby returning the engine
to a normal condition. Be sure to use a genuine Mitsubishi
cleaning additive. Using an unsuitable additive could
make the engine malfunction. For details, please contact
the nearest authorized Mitsubishi Motors dealer.
