Cleaning additive to be added directly in the lubrication circuit. Thanks to this additive, compression is increased, engine runs cleaner, creates less pollutants emissions, is more protected and offers higher performances. It lowers also consumption and works as a deposit and residue remover from piston rings, gaps, hydraulic valve lifters and valve train. Engine Clean efficiently dissolves contamination and deposits in the oil system. These are then mixed with the oil to be easily removed during the oil change. Motul Engine Clean contains highly effective anti-friction properties that reliably protect the engine during the cleaning process.Engine cleaner before drainAdditive to add to engine oil before oil drainBefore each oil drain, add in the engine a can of ENGINE CLEAN to hot used oil. Let the engine run at idle for 15 minutes. Drain the oil and change the oil filter.The content of one can is sufficient for an oil capacity up to 5 litres. For higher capacities, 60 ml of ENGINE CLEAN is to be added per additional litre of engine oil (over 5 litres). Do not exceed the recommended proportion. If necessary, proceed to 2 successive treatments.Combined with DIESEL SYSTEM CLEAN or FUEL SYSTEM CLEAN, ENGINE CLEAN provides a very appreciable reduction of pollutants emissions to pass Vehicle Inspection.SECURITYRefer to the MSDS sheet and the information mentioned on the product label.Viscosity: Quality: For Gasoline and Diesel car engineStandarts: Approvals: Performance Division: Additives & Workshop.
