What makes the catalytic converter go bad?

Many of the compounds that make your engine oil work better on the INSIDE of the engine are also "poisonous" to your catalytic converter as your engine starts to use oil. The nice thing about catalytic converters, they burn unused hydrocarbons that come out the exhaust. You may not KNOW that your engine is burning oil until the catalytic converter gives out or even gets plugged up. Watch the oil level in the crankcase. If it drops with no evidence of leaking, it's burning and your catalytic converter will die.
