Understanding Engine Knocking:
Engine knocking is a very common issue that affects cars of all makes and models.
It’s usually heard as either a light ticking noise or loud knocking sound coming from the engine when running, and could indicate problems with combustion processes inside of it that could cause serious damage if left unchecked.
If left untreated, engine knocking may become worse over time.
Reasons for Engine Knocking After an Oil Change:
Engine knocking can occur for various reasons after an oil change, some of the most common being:
Low Oil Pressure:
Low oil pressure can lead to engine knocking as it reduces the amount of oil supplied to engine components, creating friction and heat which in turn causes engine knocking.
Incorrect Oil Type:
Using an inadequate type of oil can lead to engine knocking noises. Oil that’s either too thin or thick may affect lubrication around engine components, leading to noises.
Oil Filter Issues:
A clogged or dirty oil filter can lead to engine knocking by decreasing the amount of oil supplied to the engine.
Oil Additives:
Some oil additives can lead to engine knocking, particularly if they contain chemicals that are incompatible with your car’s engine.
Oil Pump Issues:
An inefficient oil pump can lead to engine knocking, as it reduces the amount of oil supplied to critical engine components.
Engine Wear and Tear:
Over time, engine components may wear out and cause knocking noises.
This is more common in older cars or those that have not been properly maintained.
Signs of Engine Knocking After an Oil Change:
The most obvious indication that your engine might need attention after an oil change is a knocking or tapping sound coming from the engine.
Other telltale signs may include reduced engine power, misfires, excessive exhaust smoke, poor fuel economy, and overheating.
If you observe any of these warning signs, it’s essential to address the problem promptly in order to prevent costly engine damage.
