Hydraulic lifter additives are designed to enhance engine performance, reduce operational noise, and prolong the life of hydraulic systems. They come in various types, such as the Wynn’s Hydraulic Valve Lifter, which is an oil-soluble supplement that eliminates deposits inside the engine, thus reducing noise and improving efficiency. Another example is the LIQUI MOLY hydraulic lifter additive, suitable for all commercial motor oils in gasoline and diesel engines, both with and without diesel particulate filters. These additives play a crucial role in maintaining the performance of hydraulic systems and preventing hydraulic fluid leaks.

Understanding how hydraulic lifter additives work is the first step to appreciating their benefits. One significant aspect of their functionality lies in addressing internal hydraulic fluid leaks by improving the lubrication and sealing properties of the oil. By understanding the various hydraulic lifter additives available and their functions, you can make an informed decision on which additive is suitable for your system.

Benefits of Using Hydraulic Lifter Additives

Utilizing hydraulic lifter additives offers numerous advantages, such as preventing and diminishing hydraulic lifter noise, cleaning oil passages to eliminate oil flow restrictions, and restoring appropriate hydraulic lifter function.

Beyond noise reduction and wear prevention, hydraulic lifter additives also enhance hydraulic cylinder performance. They assist in cleaning oil passages and breaking down sludge and other deposits that could impede oil flow. This, in turn, helps maintain the performance of hydraulic cylinders by ensuring proper lubrication and reducing wear. The benefits of using hydraulic lifter additives extend not only to the individual components of the system, but also to the overall performance and longevity of the hydraulic equipment.

How Hydraulic Lifter Additives Work

Hydraulic lifter additives function by removing deposits, improving lubrication, and sustaining ideal viscosity. Viscosity is a measure of a hydraulic oil’s resistance to flow, and as temperature increases, the viscosity of engine oil will decrease. As temperatures drop, engine oil thickens and becomes increasingly viscous. This is opposite from when temperatures rise as the oil thins out. Monitoring for external leak issues is also an important aspect of maintaining a well functioning engine with the correct engine compression.

LIQUI MOLY hydraulic lifter additive enhances performance by cleaning oil holes and ducts in the oil circuit, which in turn boosts the functioning of oil pressure-filled timing chain tensioners, potentially reducing timing chain noise. Wynn’s Hydraulic Valve Lifter cleans away deposits inside the engine, further contributing to the overall effectiveness of the additive.

A grasp on how hydraulic lifter additives function facilitates a deeper understanding of their role in hydraulic fluids and their influence on your system’s performance.

Choosing the Right Hydraulic Lifter Additive

Considerations such as brand, oil type, and viscosity are key when choosing the right hydraulic lifter additive. Popular additives from LIQUI MOLY and other brands such as Castrol, Valvoline, and Mobil offer various benefits for different applications. It’s important to choose an additive that is compatible with your engine and adheres to the manufacturer’s specifications.

Beyond brand and compatibility, the type of oil is also a significant factor in the selection process. There are two main types of oils: mineral oils and synthetic oils. Mineral oils are derived from petroleum and are typically more economical than synthetic oils, while synthetic oils are manufactured and engineered to provide superior performance and protection. Understanding the differences between mineral and synthetic oils can help you make an informed decision when maintaining a well functioning hydraulic lifter system.

Most popular Hydraulic Lifter Additives from LIQUI MOLY and other brands

The most popular hydraulic lifter additive from LIQUI MOLY is their Hydraulic Lifter Additive, designed to reduce hydraulic tappet noise and compatible with all commercial motor oils for both gasoline and diesel engines. This additive can help reduce engine wear and tear, optimize performance, and minimize noise, making it a popular choice for many users.

Other brands of hydraulic lifter additives available on the market include Castrol, Valvoline, and Mobil. Each brand offers its unique formulation and benefits, catering to different applications and requirements. Comparing the benefits and differences of popular additives will help you discern the most suitable product for your engine oil and hydraulic lifter system, ensuring optimal performance and durability.

Mineral Oils vs. Synthetic Oils

A key component in the performance of engines and hydraulic lifters is using mineral oils vs. synthetic oils.

Mineral oils are obtained from crude oil and contain contaminants. They are more cost-effective than synthetic oils, making them a popular choice for budget-conscious consumers.

However, when it comes to performance and longevity, synthetic oils have the upper hand. Synthetic oils can be formulated to provide better physical properties when compared to mineral oils. They possess a higher viscosity index, improved resistance to oxidation, and thermal degradation, ultimately offering enhanced performance and longevity.

Understanding the distinctions between mineral and synthetic oils empowers you to make an informed choice regarding the ideal oil type for your hydraulic lifter system and corresponding hydraulic lifter additive.

Viscosity Considerations

Viscosity is a crucial factor in technical fluids, affecting the system’s performance and efficiency. The viscosity index (VI) is utilized to measure the alteration in viscosity of hydraulic oil when the temperature fluctuates. The viscosity of an engine oil changes drastically with shifts in temperature if it has a low viscosity index. On the other hand, a high viscosity index provides better resistance to such temperature shifts. Hydraulic oil with a high viscosity index (VI) is typically recommended for applications with a broad range of ambient and/or operating temperatures.

When selecting a hydraulic lifter additive, one should take into account the viscosity of the oil. This is because the viscosity of the oil affects the flow rate and pressure of the hydraulic system. Taking into account the oil’s viscosity and its effect on system performance allows you to make a well-informed decision about the best hydraulic lifter additive for your system.

Application and Maintenance Tips
