The catalytic converter is a reliable and simple device that does not require any maintenance in itself, but there are some recommendations that the owner must follow to ensure that the converter functions properly throughout its entire service life.

- a) DO NOT use leaded gasoline in a vehicle equipped with a catalytic converter, this will reduce the conversion efficiency and eventually cause converter failure.
- b) Always maintain the ignition system and fuel system in good condition.
- c) If the engine misfires, do not operate the vehicle at all (or at least as little as possible) until the damage is repaired.
- d) DO NOT attempt to tow start the vehicle - the catalytic converter will become soaked with unburned fuel, which may cause the engine to overheat after starting.
- e) DO NOT turn off the ignition at high engine speeds.
- f) DO NOT use fuel or engine oil additives - they may contain substances harmful to the catalytic converter.
- g) DO NOT operate the vehicle if the engine is observed to be burning oil (blue smoke).
- h) Remember that the catalytic converter operates at very high temperatures. DO NOT park the vehicle on dry leaves, long grass.
- i) Remember that the catalytic converter is FRAGILE - do not hit it with tools during servicing.
- j) In some cases, a hydrogen sulfide odor may be felt from the exhaust system (like the smell of rotten eggs). This is normal for many vehicles equipped with a catalytic converter. After a few thousand kilometers, the problem should disappear.
- k) The service life of a catalytic converter on a well maintained vehicle should be between 80,000 and 160,000 kilometers - if the efficiency of the converter is reduced, replace it.
