To avoid damage to the catalytic converter, follow these recommendations:
- a) Use only unleaded petrol;
- b) Perform a forced start of the engine by pushing or towing only once and for a distance of no more than 50 meters, but it is best to use an auxiliary battery in this case. Unburned fuel during ignition can cause overheating and destruction of the catalytic converter. If the engine is warm, then forced starting by pushing or towing is not allowed at all;
- c) if the engine is difficult to start, do not operate the starter for too long. When starting the engine, fuel is continuously injected. In such cases, it is necessary to find and eliminate the cause of the malfunction;
- d) monitor the amount of fuel in the tank and avoid "emptying" it;
- d) if misfires are observed, it is necessary to avoid high engine speeds and immediately eliminate the malfunction;
- e) Install only those types of spark plugs that are recommended by the vehicle manufacturer;
- g) Do not perform spark testing with the spark plug tip removed:
- h) do not compare cylinders by disabling the ignition in the combustion chamber of one cylinder. When disabling in this way, including with the help of an engine test stand, unburned fuel gets into the catalyst;
- i) Do not park the vehicle over dry leaves or grass. The exhaust system in the catalytic converter area is very hot and emits heat even after the engine is turned off;
- k) When filling and topping up engine oil, pay special attention to not exceeding the maximum oil level mark on the dipstick. Excess oil gets into the catalyst due to incomplete combustion and can damage the precious metal or completely destroy the catalyst.
