MMT In Gasoline
MMT is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasolines
blended with MMT provide no performance advantage
beyond gasolines of the same octane number without
MMT. Gasolines blended with MMT reduce spark plug
life and reduce emission system performance. We recom-
mend that gasolines free of MMT be used in your vehicle.
The MMT content of gasoline may not be indicated on
the gasoline pump; therefore, you should ask your gaso-
line 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 levels
higher than allowed in the United States. MMT is pro-
hibited in Federal and California reformulated gasolines.
Materials Added To Fuel
All gasolines sold in the United States are required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in unnecessary cost. There-
fore, you should not have to add anything to the fuel.
ADDING FUEL
NOTE:If fuel is poured from a portable container, the
container should have a flexible nozzle long enough to
extend into the fuel filler tube.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE:When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.

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, 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.
•When pulling a heavy load or driving a fully loaded vehicle
when the humidity is low and the temperature is high, use a
premium unleaded fuel to help prevent spark knock. If spark
knock persists, lighten the load, or engine piston damage may
result.
•The use of fuel additives which are now being sold as octane
enhancers is not recommended. Many of these products con-
tain high concentrations of methanol. Fuel system damage or
vehicle performance problems resulting from the use of such
fuels or additives is not the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.

temperature starting and vehicle fuel economy. Refer to
your engine oil filler cap for the recommended engine
oil viscosity for your vehicle.
For information on engine oil filler cap location, see the
Engine Compartment illustration in this section.
Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Synthetic Engine Oils
There are a number of engine oils being promoted as
either synthetic or semi-synthetic. If you chose to use
such a product, useonlythose oils that meet the Ameri-
can Petroleum Institute (API) and SAE viscosity stan-
dard. Follow the service schedule that describes your
driving type.
Materials Added to Engine Oils
The manufacture strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and
it’s performance may be impaired by supplemental ad-
ditives.
Disposing of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your dealer, service station, or
governmental agency for advice on how and where used
oil and oil filters can be safely discarded in your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
