Is an Engine Flush Worth It?
Should you pay for an engine flush at service time? A Cranbourne West specialist gives the honest answer.
What a flush does — and the risk
An engine flush adds a cleaning agent before an oil change to loosen sludge and deposits. On a well-maintained engine serviced on time, it’s largely unnecessary — clean oil at the right intervals keeps it clean. On a very neglected, sludgy engine, a flush can actually cause problems by dislodging debris that blocks oil passages.
It’s often sold as an easy add-on with more marketing than benefit.
The honest approach
For most cars, regular oil changes with the correct oil are far better than relying on flushes. If an engine is genuinely sludged from neglect, the safer fix is more frequent oil/filter changes to clean it gradually, not an aggressive flush.
