Contamination from burning oil, internal engine coolant leaks, and raw fuel from misfiring will all kill a catalytic converter prematurely. If you ever see your "check engine" light flashing shut off the vehicle. This is warning you that a misfire is happening that is killing your catalytic converter. HTH. -Jim
