Description
The Liqui Moly Hydraulic Lifter Additive is a professional-grade solution designed to prevent and reduce hydraulic lifter noise in gasoline and diesel engines. This additive effectively cleans oil passages, removing flow restrictions that can cause inconsistent oil flow and increased wear. By restoring proper hydraulic lifter function, it contributes to smoother engine operation and reduces the risk of damage caused by lifter noise. The formulation also helps dampen valve tappet noise, ensuring quieter engine performance, and improves the lubrication properties of engine oil to enhance overall engine longevity.
Suitable for use with commercial motor oils, this additive is compatible with engines equipped with turbochargers, catalytic converters, and GPF/DPF systems. It is safe for use in vehicles with advanced emission control systems, provided the recommended dosage is followed. One 300 mL can treats up to 6 liters (1.5 gallons) of motor oil, making it a cost-effective solution for regular maintenance. The additive can be added at any time during engine operation; after addition, running the engine until warm ensures optimal distribution. For sustained performance, it should be used after each oil change, maintaining clean oil passages and proper lifter function.
Liqui Moly Hydraulic Lifter Additive is an essential product for vehicle owners seeking to reduce engine noise and promote engine health. Its tested compatibility with turbochargers and catalytic converters ensures no adverse effects on emission systems. Incorporating this additive into routine maintenance routines can help extend engine lifespan and improve driving comfort by minimizing hydraulic tappet noise and ensuring consistent oil flow throughout the engine components.
