10 Best Additive For Noisy Lifters 2025 in the United States

The Liqui Moly MoS2 Anti-Friction Engine Treatment is designed to enhance engine performance by reducing friction, making it a suitable choice for car owners looking to address noisy lifters. One of its major strengths is its ability to form a high load-bearing film on friction surfaces, which can significantly improve engine sound and stability, particularly at high RPMs.

Compatibility is another positive aspect, as this additive has a universal fit type, meaning it can be used in a variety of vehicles. However, there are some considerations to keep in mind. While the product boasts impressive cleaning and lubrication properties, its effects may vary depending on the specific condition of the engine. Some users might not experience the dramatic improvements they expect, especially if their engine has been poorly maintained or is significantly worn.

Furthermore, as with many additives, it is essential to follow the manufacturer's instructions closely to achieve the best results. While the flash point of 181 degrees Celsius is adequate for most conditions, it could raise concerns for those operating in extreme environments. The Liqui Moly MoS2 Anti-Friction Engine Treatment is a solid option for car owners looking to minimize engine noise and enhance performance, particularly for noisy lifters, but individual results can vary, and proper maintenance is key to getting the most out of any additive.

The Liqui Moly 20004 Hydraulic Lifter Additive stands out as a strong option for those looking to improve their vehicle's engine performance, particularly for noisy hydraulic tappets. One of its notable strengths is its ability to enhance the lubrication properties of engine oil, which can lead to smoother operation and less engine noise. This additive also cleans valve bores effectively, helping to maintain engine cleanliness and efficiency. It is suitable for a wide range of vehicles, including those equipped with turbochargers and catalytic converters, making it versatile for different engine types.

While the product has numerous benefits, it may not address all types of engine noise or issues related to hydraulic lifters, especially if there are underlying mechanical problems. Users should also be cautious about overusing additives, as excessive lubrication might lead to other complications. The flash point of 60 degrees Celsius indicates some level of caution required during storage and handling.

If you're dealing with noisy lifters and are looking for a reliable additive that cleans and lubricates effectively, the Liqui Moly 20004 is a solid choice. Just remember that it works best as a supplement to regular maintenance and is not a substitute for addressing more serious engine issues.

The Sea Foam SF-16-12PK Motor Treatment is designed as a versatile fuel and oil system additive, making it particularly suitable for those looking to improve engine performance and cleanliness. One of its main strengths is its compatibility with various engine types, helping to clean carburetor jets and fuel injectors while also removing harmful deposits like carbon, gum, and varnish. This dual action not only enhances lubrication but also helps stabilize fuel for up to two years, which can be beneficial for users who store their vehicles for extended periods.

However, there are some drawbacks to consider. The product has been discontinued by the manufacturer, which could pose a challenge for those wanting to rely on it long-term. Also, while many users report positive outcomes, results can vary depending on the condition of the engine and the extent of the problems being addressed. Newer users may also find the application process a bit daunting if they're unfamiliar with using additives.

The Sea Foam SF-16 is a solid choice for those seeking an additive to combat noise and improve engine performance. It's particularly useful for individuals who maintain older or neglected engines, but potential buyers should be aware of its discontinuation and ensure they’re comfortable with its use.
