Dodge 2004 Ram SRT-10 - Manual (Page 188)

CATALYTIC CONVERTER
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device. Under normal
operating conditions, the catalytic converter will not
require maintenance. However, you must keep the en-
gine maintained to assure proper operation and prevent
possible damage.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
