Motul Engine Clean is designed to be used in all types of gasoline and diesel engines, naturally aspirated or turbocharged, with or without catalytic converter. This oil additive effectively cleans deposits and clogging which appear in the engine. The removed micro-particles are then evacuated when the oil is drained. Engine Clean also decreases oil and fuel consumption, as well as helps to restore the engine's compression. It adds a layer of protection by providing perfect lubrication during the cleaning process.
