MMT is a manganese-containing metallic
additive that is blended into some gasoline to
increase octane. Gasoline blended with MMT
provides no performance advantage beyond
gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark
plug life and reduces emissions system
performance in some vehicles. The manufacturer
recommends that gasoline without MMT be used
in your vehicle. The MMT content of gasoline may
not be indicated on the gasoline pump, therefore,
you should ask your gasoline retailer whether the
gasoline contains MMT. MMT is prohibited in
Federal and California reformulated gasoline.

Besides using unleaded gasoline with the proper
octane rating, gasolines that contain detergents,
corrosion, and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, reduce
emissions, and maintain vehicle performance.
Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in
minimizing engine and fuel system
deposits. When available, the usage of Top Tier
Detergent Gasoline is recommended. Visit
www.toptiergas.com for a list of TOP TIER
Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish
removal may contain active solvents or similar
ingredients. These can harm fuel system gasket
and diaphragm materials.

NOTE:
Intentional tampering with the emissions
control system can result in civil penalties being
assessed against you.
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can
impair engine performance and damage
the emissions control system.
An out-of-tune engine or certain fuel or igni
-
tion malfunctions can cause the catalytic
converter to overheat. If you notice a pungent
burning odor or some light smoke, your
engine may be out of tune or malfunctioning
and may require immediate service. Contact
an authorized dealer for service assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle perfor
-
mance problems resulting from the use of
such fuels or additives is not the responsi
