The Liqui Moly Pro-Line Engine Flush (500ml) is an essential treatment for vehicle owners aiming to thoroughly clean their engine's internal components, ensuring optimal performance and longevity. Its primary function is to dissolve and remove harmful deposits, allowing fresh engine oil to perform at its peak; however, it is crucial to use this product precisely as directed, immediately before an oil and filter change.
Comprehensive Internal Cleaning: Effectively removes deposits from vital engine parts, including oil holes, bearings, and the piston ring area.
Performance Restoration: Helps reduce engine noise and oil consumption while improving compression, leading to increased operating reliability.
Optimized Oil System Function: Ensures the perfect hydraulic operation of advanced oil-controlled systems such as VVT (Variable Valve Timing), VANOS, and similar technologies.
Broad Engine Compatibility: Suitable for all gasoline and diesel engines, including those equipped with diesel particulate filters (DPF/GPF) and vehicles where the toothed belt runs in oil.
Material Safety: Formulated not to attack common sealing materials and extensively tested for safe use with catalytic converters and turbochargers.
Economical Application: A single 500ml bottle is precisely measured to treat up to 5 liters of engine oil.
Rapid and Gentle Action: Provides quick and gentle cleaning, ensuring effective deposit removal without harming sensitive engine components.
Thorough Deposit Removal: Deep cleans the engine interior, clearing sludge and varnish.
Improved Engine Health: Contributes to reduced wear, lower oil consumption, and better compression.
Enhances New Oil Performance: Allows new oil to fully lubricate and protect the engine without immediate contamination.
Wide Compatibility: Safe for a vast range of modern and older gasoline and diesel engines, including those with DPFs and turbos.
Ease of Use: Simple application process requiring minimal mechanical skill.
Requires Immediate Oil Change: Mandates an immediate oil and filter change, adding to the overall service cost and time.
Engine Idling Required: Engine must idle for 10-15 minutes after application, which may not always be convenient.
Not a Preventative Additive: Designed as a pre-oil change cleaning treatment, not a continuous-use oil additive.

The Liqui Moly Pro-Line Engine Flush is engineered to tackle internal engine contamination that conventional oil changes might leave behind. Over time, engine oil can leave behind carbon, varnish, and sludge deposits due to combustion byproducts and oil breakdown. These deposits can restrict oil flow, impede lubrication, and reduce engine efficiency.
Upon addition to warm engine oil, the flush's active cleaning agents rapidly circulate throughout the oil system. They work to dissolve and suspend these stubborn deposits from critical areas such as:
Oil passages and galleries: Ensuring unobstructed flow of fresh oil.
Bearing surfaces: Allowing proper lubrication and reducing friction.
Piston ring grooves: Freeing up sticky piston rings to improve compression and reduce blow-by, which can lower oil consumption.
Hydraulic lifters and VVT/VANOS components: Clearing blockages that can cause noisy operation or improper timing adjustments.
Users can expect to notice improvements in engine smoothness and potentially a reduction in engine noise after an oil change following the flush. By removing old contaminants, the fresh engine oil can immediately provide optimal lubrication and protection, extending its effective lifespan and enhancing overall engine reliability. This is particularly beneficial for vehicles with unknown service histories, or those that have experienced extended oil change intervals.
Application Scenario Example: A driver notices their older diesel engine has a slightly rough idle and higher than usual oil consumption. Before their next scheduled oil change, they apply the Liqui Moly Pro-Line Engine Flush. After following the instructions to idle the engine for 15 minutes, they perform a complete oil and filter change. The fresh oil, free from immediate contamination, can now effectively lubricate all engine components. The engine's idle smooths out, and subsequent oil consumption measurements show an improvement, demonstrating the flush's ability to free up piston rings and optimize internal function.
Proper application of the Liqui Moly Pro-Line Engine Flush is crucial for maximizing its benefits and ensuring engine safety.
Warm Up Engine: Ensure your vehicle's engine is at operating temperature. This allows the current engine oil to be fluid and helps the flush distribute effectively.
Add Flush: With the engine still running or immediately after turning it off, carefully pour the entire 500ml contents of the Liqui Moly Pro-Line Engine Flush into the engine's oil filler opening. One 500ml bottle is designed for up to 5 liters of engine oil.
Idle Engine: Restart the engine (if it was turned off) and allow it to idle for 10 to 15 minutes. The exact duration depends on the perceived degree of contamination within the engine. Do not drive the vehicle during this time.
Oil & Filter Change: Immediately after the idling period, turn off the engine. Proceed to drain the old engine oil completely and replace the old oil filter with a new one. This step is critical to remove the dissolved contaminants and the flush liquid itself from the engine.
Refill with Fresh Oil: Fill the engine with the manufacturer-recommended new engine oil.
Engine Types: Universally compatible with all gasoline and diesel engines.
Particulate Filters: Safe for use in vehicles equipped with Diesel Particulate Filters (DPF) or Gasoline Particulate Filters (GPF).
Oil-Controlled Systems: Ensures perfect function of hydraulic oil-controlled systems like Variable Valve Timing (VVT) and VANOS.
Toothed Belts in Oil: Can be safely used in engines where the timing belt runs directly in oil.
Sealing Materials: Formulated not to attack common engine sealing materials.
Exhaust Systems: Tested for use with catalytic converters and turbochargers without causing damage.
Motor Oils: Compatible with all commercially available motor oils.
Store the product in a cool, dry place away from direct sunlight.
Keep out of reach of children and pets.
Always refer to your vehicle's owner's manual for specific oil change procedures and recommendations.
Dispose of used engine oil and filter responsibly according to local regulations.
