The additive blends with existing engine oil and is intended for periodic use to help restore smoother valve-train movement and reduce audible tapping. It’s supplied in two bottles, providing enough product for multiple treatments depending on engine size and service intervals.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this additive help noisy hydraulic lifters?\u003c\/h3\u003e\n\n\u003cp\u003eThe formula works by improving lubrication at the contact surfaces and mobilizing deposits that restrict lifter movement, which can be a source of tapping or ticking sounds. While individual results depend on the severity of wear and existing deposits, regular treatments aim to reduce audible lifter noise and restore more consistent lifter action.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eBoosts oil film strength for improved lubrication under pressure.\u003c\/li\u003e\n  \u003cli\u003eSoftens and dislodges varnish, sludge and lacquer from tappet channels.\u003c\/li\u003e\n  \u003cli\u003eCompatible with hydraulic lifter assemblies to aid smoother operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this product mix with my engine oil and when should I use it?\u003c\/h3\u003e\n\n\u003cp\u003eLiqui Moly Hydraulic Lifter Additive is formulated to mix readily with conventional and synthetic engine oils.
