What Is Engine Sludge (and How to Avoid It)?
Engine sludge quietly destroys engines. A Cranbourne West specialist explains how to avoid it.
What it is & what it does
Engine sludge is a thick gunk that forms when oil degrades and isn’t changed often enough — it blocks oil passages and starves parts of lubrication. Short trips, stretched oil intervals and the wrong oil all accelerate it.
Some engines (and stretched long-life intervals) are especially prone to it.
Signs of trouble & how we help
Sludge causes oil-pressure warnings, ticking/knocking, overheating and, untreated, engine failure. Prevention is everything: fresh, correct-spec oil at sensible intervals.
We service with the correct oil on sensible intervals — the single best defence — and assess any engine we suspect of sludge before recommending work.

Oil-pressure warnings, ticking/knocking, overheating — untreated it causes engine failure.
Fresh, correct-spec oil at sensible intervals — the best defence by far.
Sometimes gradually with more frequent oil changes — aggressive flushes can be risky. We advise per engine.
