2004 DODGE VIPER octane

FUEL REQUIREMENTS
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high quality pre-
mium unleaded gasoline having an octane
rating of 93 or higher.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required. Engine damage resulting from operating with a
heavy spark knock may not be covered by the new
vehicle warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of ªregularº gasoline be-
fore considering service for the vehicle.Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) to define
fuel properties necessary to deliver enhanced emissions,
engine performance, and durability for your vehicle. The
manufacturer recommends the use of gasolines that meet
the WWFC specifications if they are available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning fuel referred to as Reformulated Gasoline.
Reformulated gasolines contain oxygenates, and are spe-
cially blended to reduce vehicle emissions and improve
air quality.
The manufacturer strongly supports the use of reformu-
lated gasolines. Properly blended reformulated gasolines
will provide excellent performance and durability of
engine and fuel system components.

Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with mate-
rials called oxygenates such as 10% alcohol, MTBE, ETBE
or TAME. 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.
Gasoline containing methanol may damage critical
fuel system components.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane. Gaso-
lines blended with MMT offer 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 in some
vehicles. The manufacturer recommends that gasolines
without 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 are allowed in the United States. MMT is
prohibited in Federal and California reformulated gaso-
lines.
