Engine Flush is a solvent-free, engine cleaning formulation that removes engine deposits, sludge and contaminants with the oil service drain. It contains added zinc for engine wear protection and its fast-acting formulation works in 10 minutes. The solvent-free formulation protects gaskets and seals from damage during the cleaning process.


Engine Flush is designed for use in all engine types in passenger cars, 4WDs, light & heavy-duty commercial vehicles, motorcycles, farming, mining, agricultural, industrial equipment, and marine and stationary engines.

Engine Flush is safe to use in all petrol, LPG & diesel engines and is safe for catalytic converters, DPFs (Diesel Particulate Filters) and engine sensors. Its unique formulation of cleaning agents is designed to clean oil galleries, oil sludge and engine contaminants that affect the lubrication of the engine. These contaminants are broken down by the Engine Flush and drained away with the oil service.

Engine Flush is economical to use with an application rate is 50 ml Engine Flush per litre of oil. A 375ml bottle of Engine Flush will treat 7.5 litres of oil. Engine Flush is recommended for use at every oil service to maintain engine cleanliness.
