Liqui Moly | Engine Flush Plus Internal Engine Cleaner - 300mL

Liqui Moly Engine Flush Plus 300mL (Model: LIQ8374-2) is a professional-grade, highly effective technical chemical flushing agent engineered with an advanced German formula to deep-clean the interior of combustion engines. Specially developed to dissolve and purge performance-robbing contaminants, this premium additive rapidly flushes away stubborn sludge, soot, and carbon varnishes with absolute reliability. It functions by chemically suspending all oil-soluble and oil-insoluble residues within the old lubricant layer, ensuring they are entirely evacuated during the subsequent oil change. This comprehensive engine flush enhances overall mechanical efficiency, guarantees a smooth powertrain idle, and prepares the crankcase environment for fresh oil, allowing the new lubricant to develop its protective characteristics at peak performance.

Product Specifications:

• Brand: Liqui Moly

• Product Type: Internal Engine Cleaning Oil Additive

• Volume: 300 mL 

• Canister Color: Premium Metallic Grey with a secure black sealing cap

• Country of Origin: Germany 

Key Features & Performance:

• Deep Action Oil Circuit Cleansing: Meticulously flushes the entire oil delivery path, disintegrating baked-on oil residues and accumulated grease caused by thermal stress or delayed maintenance.

• Suppresses Mechanical Friction & Noise: Minimizes parasitic internal wear and eliminates harsh, unneeded engine ticks triggered by caked residues, specifically targeting noisy hydraulic lifters (Lifter Noise).

• Optimizes Oil Circulation & Cooling: Restores unrestricted oil flow through micro-galleries, directly boosting the operational capacity of both the lubrication and thermal cooling systems.

• Maximizes Vehicle Fuel Economy: Lowering internal mechanical resistance enables the powertrain to rotate smoothly, yielding a measurable improvement in fuel efficiency.

• Shields Fresh Oil Integrity: Completely removing old deposits prevents the immediate chemical contamination of your newly added motor oil, preserving its full viscous lifespan.

Usage Instructions:

• One compact 300mL can of Liqui Moly Engine Flush Plus is perfectly calibrated to treat engine oil capacities up to 6 liters.

• Before executing a scheduled oil change service, pour the entire contents of the 300mL can directly into the warm engine crankcase through the oil filler neck.

• Start the ignition and allow the engine to idle stationary for 10 to 15 minutes; do not drive the vehicle, rev the engine, or apply throttle pressure during this flushing phase.

• Turn off the ignition immediately after the time expires, drain the contaminated old oil completely while still warm, and replace the old oil filter with a fresh unit.

• Refill the clean engine with high-quality, factory-recommended fresh motor oil.

Suitability & Applications:

• Formulated and safety-tested for flushing the oil circuits of all standard gasoline and diesel engines; completely safe for implementation with commercial mineral or synthetic oils, and entirely neutral toward internal rubber seals, O-rings, and valve stem packings.

Note:

This formulation is a highly volatile chemical cleanser designed for temporary idling service only; never drive the vehicle or strain the engine while the flush is mixed with the oil to prevent bearing damage. It is strictly not suitable for use on motorcycles equipped with wet clutches to avoid clutch slippage, and must never be added to the fuel tank or radiator.
