If you notice your vehicle emitting black smoke from the exhaust pipe, should you have it checked?

Question

DentroTest · Accepted Answer

Yes, it is necessary to check it immediately. Black smoke is a clear symptom of poor combustion, generally caused by a mixture that is too 'rich' (excess fuel or lack of air). Common causes include a clogged air filter or faults in the injection system. This not only spikes fuel consumption but drastically increases polluting emissions. To differentiate it from other breakdowns: If the smoke were bluish, it would indicate the engine is burning oil. If the smoke were thick and white (when the engine is hot), it could signal a failure in the cooling system (head gasket).
