How should I treat the engine knocking sound of the Mahindra Centuro? / Centuro Questions Mahindra

Engine knocking sound occurs when the air-fuel mixture in the engine does not burn in an optimal manner which causes the engine to produce a pinging or metallic noise. Causes of the same are:

• carbon deposits
• A lean air-fuel mixture
• low level of coolant in the system causing the engine to ride hotter than normal.

I highly advise you to kindly get in touch with your nearest Mahindra authorised service centre for repair and maintenance.
