Left untreated, it can cause damage to the piston and cylinder wall. A knocking sound can also be caused by a lack of lubrication in the upper cylinder head area.
Can you drive a car with a knocking engine?

How do you stop knocking?
Always fuel from a reputable gas station with good fuel quality. Change your spark plugs as often as required and not just when they are worn out. Reduce the throttle immediately you hear any engine knocking or pinging. Use high-quality fuel additives to minimize carbon build-up.
Can low oil cause engine knocking?
