Engine Sludge and How to Prevent It

June 8, 2019MechVibesblog

Engine oil sludge – what it is and how to prevent?, Is a combination of oxidized oil and contaminants that have settled and been dispersed onto engine surfaces.

Sludge affects both petrol and diesel engines, and is surprisingly common.

Engines have changed over the years, becoming more efficient and less polluting while lasting longer.

Sludge is a gooey deposit that reduces or shuts off oil circulation and is exactly what it sounds like an accumulation of dark, greasy, and tarry deposits inside the engine crankcase.

Furthermore, sludge is a mixture of engine oil that has been oxidized with soot and dirt from the atmosphere which the engine takes in for combustion.

Engines are designed to run with clean motor oil. With the presence of engine sludge, the oil will hardly lubricate to cool the engine.

Oils that can handle higher RPM’s and tougher conditions. These oils have more additives in them to suspend soot particles and maintain oil viscosity.

When engine temperature rises, oil breaks down faster and low viscosity oils break down faster than heavier oil.
