ZDDP Lubricant Additive Overview

Zinc dialkyldithiophosphate, commonly known as ZDDP, is a widely used lubricant additive that has been around for decades. It is known for its ability to improve engine wear protection and reduce friction, making it a popular choice for oil manufacturers. In this article, we will discuss the compatibility of ZDDP with different engines and lubricants, its mechanism of action, potential side effects or disadvantages, usage frequency, and storage and packaging methods.

Compatibility of ZDDP with Engines and Lubricants

ZDDP is compatible with various types of engines and lubricants, including gasoline and diesel engines, as well as synthetic and mineral-based lubricants. It is particularly effective in protecting flat-tappet camshafts in older engines, as the high pressure and sliding friction between the camshaft and lifters can cause wear. However, it should be noted that engines equipped with catalytic converters are not compatible with high concentrations of ZDDP. This is because ZDDP contains phosphorus, which can damage the catalytic converter over time. Therefore, please use the ZDDP series under our guidance.

Mechanism of Action

ZDDP reduces friction and wear by forming a protective layer on metal surfaces. When the engine is running, ZDDP reacts with the metal surface to form a friction film, which is a thin layer of protective material adhered to the metal surface. This friction film acts as a barrier between metal surfaces, reducing friction and wear. In addition, ZDDP also has antioxidant and anti-corrosion properties, helping to extend the life of the lubricant.

Usage Frequency

The frequency of ZDDP use depends on several factors, including the age and condition of the engine, the type of lubricant used, and the level of ZDDP in the oil. Generally, older engines with flat-tappet camshafts require more ZDDP to provide sufficient wear protection. However, modern engines equipped with roller camshafts can reduce the frequency of use.

Storage and Packaging Methods

Our ZDDP is sealed and stored in 190kg or ton drums and should be placed in a cool, dry place away from sunlight and heat sources.

When handling ZDDP, it is important to wear protective gloves and goggles to avoid skin contact and eye irritation.
