Petrol engines
- a) Use only unleaded petrol;
- b) Forced starting of a warm engine by pushing or towing is not permitted. In this case, it is recommended to use an auxiliary battery. Unburned fuel, when ignited, can cause overheating and destruction of the catalytic converter;
- 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;
- g) Install only those types of spark plugs that are recommended by the vehicle manufacturer;
- h) Perform a spark test only with the spark plug tip removed, after disconnecting the fuel pump power relay;
- i) Do not compare cylinders (balance test) by disabling the ignition in the combustion chamber of one cylinder. When this is done, including with the help of a tester to check the engine operation, unburned fuel gets into the catalyst;
Cars with petrol and diesel engines
- k) Do not park the vehicle over dry leaves or grass. The exhaust system in the area of the catalytic converter is very hot and radiates heat even after the engine is turned off;
- l) Do not apply anti-corrosion protection for the underbody to exhaust system components;
- m) Do not modify the exhaust system heat reflectors;
- n) When filling and topping up engine oil, make sure that the maximum oil level mark on the dipstick is not exceeded. Excess oil gets into the catalyst due to incomplete combustion and can damage the noble metal or completely destroy the catalyst.
