Liqui Moly Engine Flush Plus 300ml 8374
Liqui Moly Engine Flush Plus 300ml is a powerful yet gentle engine oil-system cleaner designed to dissolve sludge, lacquer-forming deposits and other contamination from the internal oil circuit before an oil change.
Its specially formulated combination of carrier fluid, detergents and dispersant additives dissolves deposits and brings both oil-soluble and oil-insoluble residues into suspension, allowing them to be drained from the engine together with the old oil.
Removing accumulated contamination helps prevent fresh engine oil from immediately becoming mixed with old deposits and impurities. A cleaner lubrication system allows the new engine oil to perform effectively and helps the engine develop its full performance characteristics.
Suitable for petrol and diesel engines, including compatible vehicles equipped with turbochargers, catalytic converters and diesel particulate filters (DPF).
Key Features:
✔ Cleans the Engine Oil Circuit – Helps remove sludge, lacquer-forming deposits and other contamination from the lubrication system.
✔ Dissolves Sludge & Deposits – Powerful detergent and dispersant additives loosen accumulated residues.
✔ Removes Oil-Soluble & Insoluble Residues – Suspends contamination so it can be drained with the old engine oil.
✔ Gentle Engine Cleaning – Cleans the lubrication system without requiring engine disassembly.
✔ Rapid Cleaning Action – Requires approximately 10 minutes of engine idling before draining the old oil.
✔ Supports Optimum Engine Performance – A cleaner oil circuit allows fresh engine oil to perform without being immediately contaminated by old impurities.
✔ Helps Minimise Wear – Removing contamination from the lubrication system supports effective engine lubrication.
✔ Turbocharger Tested – Suitable for compatible turbocharged engines.
✔ Catalytic Converter Tested – Suitable for vehicles equipped with catalytic converters.
✔ DPF Compatible – Suitable for compatible diesel engines fitted with diesel particulate filters.
✔ Seal Compatible – Does not attack common engine sealing materials.
✔ No Disassembly Required – Added directly to the existing engine oil before an oil change.
✔ Compatible with Commercially Available Motor Oils – Suitable for use with conventional motor oils.
✔ Treats Up to 6 Litres of Oil – One 300ml can is sufficient for engines containing up to 6 litres of motor oil.

The need for an engine flush depends on the degree of contamination within the engine oil circuit.
How Engine Flush Plus Works:
Over time, sludge, lacquer and other residues can accumulate inside an engine's lubrication system.
Liqui Moly Engine Flush Plus contains highly effective detergent and dispersant additives that help dissolve these deposits and contamination.
Oil-soluble and oil-insoluble residues are brought into suspension within the old engine oil. When the oil is drained, the suspended contamination is removed along with it.
The engine can then be filled with fresh oil without unnecessarily carrying over as much old contamination, helping the new lubricant perform effectively.
Directions for Use:
1. Bring Engine to Operating Temperature
The existing motor oil should be at normal running temperature before treatment.
2. Add Engine Flush Plus
Add Liqui Moly Engine Flush Plus directly to the existing engine oil before changing the oil.
One 300ml can is sufficient for up to 6 litres of motor oil.
3. Idle for Approximately 10 Minutes
After adding the product, allow the engine to idle for approximately 10 minutes.
Do not drive the vehicle during the flushing process.
4. Drain the Old Engine Oil
After approximately 10 minutes, switch off the engine and drain the old oil according to the correct service procedure.
5. Replace the Oil Filter
Install a new engine oil filter.
6. Refill with Fresh Engine Oil
Fill the engine with the correct quantity and specification of fresh motor oil required by the vehicle manufacturer.
Important Notes:
Use Before an Oil Change: Engine Flush Plus is designed to be added to the old engine oil immediately before the oil and filter are replaced.
Do Not Drive During Treatment: After adding the product, the engine should only be allowed to idle for approximately 10 minutes before the oil is drained.
Not Suitable for Motorcycles with Wet Clutches: Do not use in motorcycles where the engine oil also lubricates the wet clutch.
DPF Compatible: Suitable for compatible diesel engines fitted with diesel particulate filters.
Turbo & Catalytic Converter Tested: Suitable for compatible engines equipped with turbochargers and catalytic converters.
Always Replace the Oil Filter: The engine oil and oil filter should be replaced after completing the flushing procedure.
