Hydraulic fluid additives are specialized chemical compounds added to hydraulic oils to enhance their performance properties and protect system components. They are necessary because base hydraulic oils alone cannot provide the comprehensive protection modern hydraulic systems require. These additives prevent wear in pumps and motors, protect against rust and corrosion, maintain viscosity across temperature ranges, prevent oxidation and sludge formation, control foam, and improve water separation. Without proper hydraulic fluid additives, hydraulic systems would experience premature component failure, reduced efficiency, and increased maintenance costs. Specialized versions like hydraulic lifter additive address specific challenges in engine hydraulic systems.

Hydraulic lifter oil additive works through several mechanisms to quiet noisy hydraulic lifters in engines. First, it contains strong detergents that dissolve varnish and deposits that can clog the small orifices and check valves inside lifters, restoring proper oil flow and pressure. Second, it includes anti-wear agents that protect the precision surfaces inside lifters from scuffing and wear. Third, some hydraulic lifters additive formulations contain mild seal conditioners that help maintain proper internal lifter sealing. Fourth, these additives improve the oil’s ability to bleed down air that can become trapped in lifters, causing noise. It’s important to understand that hydraulic lifter oil additive can only fix lifters that are dirty or mildly worn—mechanically damaged lifters typically require replacement.

Not all hydraulic fluid additives are compatible with all hydraulic oils. Compatibility depends on the base oil type (mineral, synthetic, or biodegradable), the existing additive package in the hydraulic oil, and the specific hydraulic system components. High-quality hydraulic fluid additives from reputable manufacturers are typically formulated for broad compatibility with common hydraulic oils, but it’s always recommended to check compatibility before mixing additives or adding aftermarket additives to fully formulated hydraulic fluids. Specialized additives like hydraulic tappet additive are generally designed for use in engine oils rather than industrial hydraulic fluids. When in doubt, consult the additive manufacturer or conduct compatibility testing with your specific hydraulic fluid before widespread application.

When used according to manufacturer recommendations, hydraulic tappet additive should not damage engine components. Reputable hydraulic tappet additive formulations are carefully balanced to provide cleaning and protection without harming engine seals, bearings, catalytic converters, or other components. However, using excessive amounts of any additive, using additives not designed for your specific application, or using poor quality additives could potentially cause issues. High-quality hydraulic tappet additive from established manufacturers like Runda Chemical undergoes extensive testing to ensure compatibility with engine materials and compliance with emission system requirements. Always follow dosage instructions and application guidelines when using any hydraulic fluid additives, including specialized engine additives.
