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.
MMT is prohibited in both Federal and California refor-
mulated gasolines.
In Canada, MMT can be used at levels higher than those
allowed in the United States. For this reason, it is even
more important to look for gasolines without MMT in
Canada.
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 normal
conditions and would result in unnecessary cost. There-
fore, you should not have to add anything to the fuel.
Sulfur in Gasoline
If you live in the Northeast United States, your vehicle
may have been designed to meet California low emission
standards with cleaner burning California reformulated
gasoline with low sulfur. If such fuels are not available in
states adopting California emission standards, your ve-
hicle will operate satisfactorily on fuels meeting Federal
specifications, but emission control system performance
may be adversely affected.
Gasoline sold outside of California is permitted to have
higher sulfur levels which may affect the performance of
the vehicle’s catalytic converter. This may cause the
Malfunction Indicator Light to illuminate. The manufac-
turer recommends that you try a different brand of

The proper SAE viscosity grade of engine oil should be
selected based on the following recommendations and be
within the operating temperature shown in the engine oil
viscosity charts.
SAE 10W-30 engine oil is preferred for use in 3.5L engines
within the operating temperatures shown in the viscosity
chart. SAE 5W-30 engine oil is allowed for use in the 3.5L
engines during cold weather only to improve cold
weather starting.SAE 5W-30 oil is preferred for use in 2.7L engines within
the operating temperatures shown in the viscosity chart.
You are highly encouraged to use SAE 5W-30 oils to aid
in low temperature starting and for improved fuel
economy.
Synthetic Engine Oils
There are a growing number of engine oils being pro-
moted as either synthetic or semi-synthetic. If you choose
to use such a product, useonlythose oils that meet the
American Petroleum Institute (APIJ) and SAE viscosity
standard. Follow the service schedule that describes your
driving type.
Materials Added To Engine Oils
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and it’s
performance may be impaired by supplemental addi-
tives.
Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil, indiscriminately discarded, can
present a problem to the environment. Contact your
