Liqui Moly engine flush plus is a highly effective cleaning fluid which is added to the engine oil prior to an oil change. It removes built up residues and deposits from the engine internals and holds them in suspension in the oil so that when it is drained the unwanted deposits are also drained. This allows the fresh oil to work to its full potential and it also stays cleaner for longer.Removes unwanted deposits, contaminants and residue from engine internalsSimply add to old engine oil before an oil changeExtends engine service lifeAllows fresh engine oil to perform to its maximum and stay cleaner for longerSafe for vehicles fitted with catalytic converters or particulate filters (DPFs)300ml bottle, treats up to 6 litres of oilTechnical Data Sheet
