LIQUI MOLY | Engine Flush Internal Engine Cleaner & Sludge Remover - 250 mL

LIQUI MOLY Motorbike Engine Flush (250 mL) is an elite, highly effective technical internal engine cleaner and sludge detergent, 100% genuine and engineered and manufactured in Germany by LIQUI MOLY—the global leader in professional engine additives and chemical optimization. Specifically formulated within the dedicated "Motorbike" division to meet the precise requirements of motorcycle engines, this premium fluid targets and chemically dissolves aggressive carbon crusts, black sludge, and baked-on varnish formations before an oil change. By liquefying both oil-soluble and insoluble residues within the old lubricant, it ensures that all deep-seated contaminants flow out smoothly during draining. This process prepares the internal mechanical environment to receive fresh oil in a 100% pristine condition, preventing premature oil degradation and extending engine operational life.

Product Specifications:

• Brand: LIQUI MOLY.

• Product Type: Internal Mechanical Sludge Dissolver and Flushing Liquid (Engine Flush).

• Volume:  (250 mL).

• Country of Origin: Germany.

Key Features & Operational Metrics:

• Aggressive Sludge & Carbon Dissolution: Quickly breaks down dense oil sludge, lacquers, and carbon deposits from critical internal core components.

• Clears Oil Passages & Piston Rings: Unclogs micro-fine oil galleries and frees up sticky piston rings, restoring optimal engine compression and lubrication balance.

• Protects Fresh Oil Performance: Prevents residual dirt and acidic oil remnants from contaminating the new oil change, keeping its viscosity stable for longer periods.

• 100% Wet Clutch Compatible: Advanced chemical engineering guarantees full compatibility with wet clutch systems; will not cause clutch slippage or degrade friction plates.

• Restores Smooth & Quiet Operation: Cleans the hydraulic valve train and reduces mechanical friction noise, restoring original engine smoothness.

Application Methodology & Technical Pro-Tips :

• Add the Engine Flush solution directly into the motorcycle's engine crankcase filler port while the old motor oil is still warm (at operating temperature) before draining.

• The 250 mL volume is highly concentrated and engineered to treat motorcycle engine oil capacities up to 4.5 Liters (recommended mixing ratio is roughly 50 mL of flush per 1 Liter of engine oil).

• After adding the product, start the engine and let it run at a steady idle for approximately 10 minutes. (Critical Safety Warning: Do NOT drive the motorcycle or rev the engine/RPM while the flushing solvent is inside the crankcase).

• Once the 10-minute cycle is complete, turn off the ignition immediately, drain the contaminated old oil completely, change the oil filter, and fill with fresh premium LIQUI MOLY motor oil.

Comprehensive System Adaptability:

• 100% verified and safe for all 4-stroke (4T) motorcycle engines, whether equipped with wet clutch assemblies or dry clutch designs. Completely compatible with all commercial engine seals, rubber O-rings, and internal gaskets.

Note:

This formula is strictly engineered for temporary flushing use and must not be left in the engine during driving; avoid direct skin contact or eye exposure. Store in a cool, well-ventilated staging bay below away from open flames, high heat, or direct sunlight. Keep out of reach of children.
