The Liqui Moly Hydraulic Lifter Additive (Part Number: 20004) is an essential treatment designed to improve the performance and longevity of gasoline and diesel engines. This 300 ml bottle is formulated to prevent and reduce hydraulic lifter noise while effectively cleaning oil passages to eliminate flow restrictions. Restoring proper hydraulic lifter function helps minimize engine wear and ensures smoother operation. This additive also dampens valve tappet noise and enhances the lubrication properties of your engine oil, promoting better engine health and efficiency.

Designed for use with commercial motor oils in engines equipped with turbochargers, catalytic converters, and GPF/DPF systems, Liqui Moly's additive is safe for these components and compatible with a wide range of vehicles. For optimal results, it is recommended to add the additive to 3-6 liters (3.17-6.34 quarts) of oil, with one 300 ml can treating up to 6 liters of oil. The additive can be introduced at any point during engine operation; simply run the engine until warm to activate its benefits. For sustained performance, it is advised to add the additive after each oil change, ensuring continuous protection and noise reduction.
The product's tested compatibility with turbochargers and catalytic converters guarantees it won't harm these sensitive components. It also improves the lubrication properties of the oil, contributing to reduced engine wear and improved efficiency. The additive cleans valve bores and maintains optimal oil flow, supporting engine longevity and smooth operation. Suitable for both gasoline and diesel engines, the Liqui Moly Hydraulic Lifter Additive is an effective solution to common hydraulic lifter issues and can be used regularly for lasting engine health.
