MMT in Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane num-
ber. Gasolines blended with MMT offer no performance
advantage beyond gasolines of the same octane number
without MMT. Gasolines blended with MMT have shown
to reduce spark plug life and reduce emission system
performance in some vehicles. The manufacturer recom-
mends using gasolines without MMT. Since the MMT
content of gasoline may not be indicated on the pump,
you should ask your gasoline retailer whether or not
his/her gasoline contains MMT.
It is even more important to look for gasolines without
MMT in Canada because MMT can be used at higher
levels than allowed in the United States.
MMT is prohibited in both Federal and California refor-
mulated gasolines.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normalconditions and would result in additional cost. Therefore
you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
or damage the emission control system.
•An out-of-tune engine, or certain fuel or ignition
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 your dealer for service assistance.
•The use of fuel additives which are now being sold as
octane enhancers are not recommended. Most of these
products contain high concentrations of methanol.
176 STARTING AND OPERATING
CAUTION!
To avoid fuel spillage and overfilling, do not“top
off”the fuel tank after filling.
NOTE:Tighten the gas cap until you hear a“clicking”
sound. This is an indication that the gas cap is properly
tightened.
The Malfunction Indicator Light will come on if the
gas cap is not properly secured. Make sure that the gas
cap is tightened each time the vehicle is refueled.
NOTE:
When the fuel nozzle“clicks”or shuts off, the
fuel tank is full.
NOTE:The fuel tank filler tube may have a restricting
door about 50 mm (2 inches) down from the opening. If
fuel is poured from a portable container, the container
should have a flexible nozzle long enough to force open
the restricting door.
CAUTION!
A poorly fitting gas cap may cause the Malfunction
Indicator Lamp to turn on.
WARNING!
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
•Never add fuel to the vehicle when the engine is
running.
•A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
