open gas tank DODGE VIPER 2004 ZB / 2.G Owners Manual

Sulfur In Gasoline
Your vehicle may have been designed to meet California
low emission standards on clean burning, low sulfur,
California gasoline. Gasoline sold outside of California is
allowed to have higher sulfur levels that may affect the
performance of your vehicle's catalytic converter. This
may cause the Malfunction Indicator Light or Service
Engine Soon Light to illuminate.
The illumination of this light while operating on high
sulfur gasoline does not necessarily mean your emission
system control system is malfunctioning. The manufac-
turer recommends that you try a different brand of
unleaded gasoline having lower sulfur to determine if the
problem is fuel related before returning your vehicle to
an authorized dealer for service.
NOTE:If the Malfunction Indicator light or Service
Engine Soon light is flashing, immediate service is re-
quired.
Materials Added to Fuel
All gasoline sold in the United States and Canada is
required to contain effective detergent additives. The use
of additional detergents or other additives is not needed
under normal conditions.
ADDING FUEL
The fuel tank filler tube has a restricting door about 2
inches (50mm) inside the opening. If using a portable
container, it should have a flexible nozzle long enough to
force open the restricting door.
