Gasoline/Oxygenate Blends; Mmt In Gasoline; Materials Added To Fuel - Dodge 2005 Neon SRT4 Owner's Manual

122 STARTING AND OPERATING
The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability for the engine
and fuel system components.

Gasoline/Oxygenate Blends

Some fuel suppliers blend unleaded gasoline with mate-
rials called oxygenates such as 10% ethanol, MTBE and
ETBE. Oxygenates are required in some areas of the
country during the winter months to reduce carbon
monoxide emissions. Fuels blended with these oxygen-
ates may be used in your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol. Gaso-
line containing methanol may damage critical fuel
system components.
Problems that result from using methanol/gasoline
blends are not the responsibility of the manufacturer.
While MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.

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 have shown to reduce
spark plug life and reduce emission system performance in
some vehicles. The manufacturer recommends that gaso-
lines 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 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 normal
