Motul Engine Flush Professional Additive – Internal Crankcase Cleaner for Motorcycles & Scooters (50ML Sachet)

Motul Engine Flush (50ML) is a high-performance, fast-acting internal crankcase cleaner specially formulated for all types of 4-stroke motorcycle and scooter engines. Over continuous operation, localized overheating and oil degradation lead to the formation of sludge, carbon deposits, varnish, and metallic soot inside the engine block. Left unchecked, these restrictions clog critical oil galleries, compromise ring sealing, and accelerate component wear.

As shown on the official packaging design in image_19dcd9.png and image_19dcdf.png, this highly concentrated 50ML sachet formula is engineered to be added directly to your old engine oil right before a routine oil change. It effectively dissolves stubborn deposits, suspends micro-particles, and ensures they drain out completely with the waste oil, leaving the crankcase interior pristine for fresh lubrication.

Key Features:

• Advanced Carbon & Sludge Dissolution: Rapidly breaks down complex thermal varnish, baked-on carbon crusts, and sticky oil sludge from internal engine walls.

• Optimizes Oil Circulation: Clears restricted oil feed pathways, galleries, and hydraulic lifter channels, ensuring fresh oil immediately reaches critical top-end components.

• Restores Cylinder Compression: Helps free sticky piston rings from their grooves, improving cylinder wall sealing, restoring lost throttle response, and optimizing fuel efficiency.

• Safe for Wet Clutches: Specially formulated for 4T motorcycle engines; contains specialized lubricants that protect wet clutch friction plates and yellow-metal bushings during the cleaning cycle.

• Maximizes Fresh Oil Lifespan: By completely purging the engine of dark, acidic residual contaminants, it prevents the immediate contamination and premature breakdown of your brand-new engine oil.

How to Use Motul Engine Flush (Step-by-Step Guide)

1. Bring Engine to Operating Temperature: Start your motorcycle/scooter and let it idle for 5–10 minutes until the engine block is warm to the touch. Switch off the ignition.

2. Add the Flush: Open the 50ML Motul Engine Flush sachet and pour the entire contents directly into the engine oil filler port (alongside your existing used oil). Tighten the oil cap.

3. Idle the Engine: Restart the engine and let it idle continuously for 10 to 15 minutes.

   ⚠️ CRITICAL WARNING: Do NOT ride the motorcycle, do NOT snap the throttle, and do NOT put the engine under load while the flush is active inside. Let it run purely at base idle speed.

4. Drain Completely: Turn off the engine. Place a drain pan underneath, remove the oil drain bolt, and let the hot, deposit-laden waste oil drain out completely.

5. Replace Filter & Refill: Always remove and replace the old oil filter element, as it will now be packed with trapped sludge. Reinstall the drain plug and refill the crankcase with fresh, factory-recommended engine oil.
