Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid
Propane (LP) may result in damage to the
engine, emissions, and fuel system
components. Problems that result from running
CNG or LP are not the responsibility of the

under the New Vehicle Limited Warranty.
MMT I G
N ASOLINE
Methylcyclopentadienyl Manganese Tricarbonyl
(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.
S
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.
M
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.
