CI-4 low-ash diesel compound additive refers to an engine oil additive specially designed for low-emission diesel engines. CI-4 refers to the performance specifications set by the American Petroleum Institute (API) for diesel engine oils, and low ash indicates reduced levels of ash-forming components in the additives. CI-4 specifications include requirements for wear protection, piston deposit…

Crude oil pour point depressants (PPDs) are chemical additives used to improve the low-temperature flow properties of crude oil by lowering its pour point—the lowest temperature at which the oil remains pourable. 🧊 What Is the Pour Point? The pour point is the temperature below which crude oil becomes too viscous or semi-solid to flow.…

CK-4/E11 is the performance specification for diesel engine oil set by the American Petroleum Institute (API). It is an upgrade from the previous CJ-4/E9 specification and is designed to provide better protection and performance for modern diesel engines. The CK-4 specification focuses on multiple areas, including wear protection, oxidation control, soot dispersion, piston deposit control,…

Choosing the right dispersant for your lubricant formulation—or fuel additive system—requires understanding both the application conditions and the chemical types of dispersants available. A dispersant’s job is to keep sludge, soot, varnish, and other contaminants suspended in the oil or fuel, preventing deposits and improving cleanliness. ✅ Key Factors When Choosing a Dispersant 1. Type…

Barium petroleum sulfonate is an important chemical raw material and is widely used in many fields. In industry, barium petroleum sulfonate is mainly used for metal anti-corrosion. As an efficient rust inhibitor and corrosion inhibitor, barium petroleum sulfonate can form a protective film on the metal surface to effectively prevent metal corrosion. In the petroleum,…

As the core component of mechanical transmission, the lubrication effect of gears directly affects the operating efficiency and service life of mechanical equipment. In order to improve the lubrication effect of gears, some additives are usually added to gear oil. Among them, extreme pressure additives are a very critical choice. They can effectively improve the…

PIB glue, also called polyisobutylene glue, is a polymer material. In the petrochemical industry, viscosity index improver is an important additive that can improve the fluidity of lubricating oil and fuel and increase engine efficiency. Among them, PIB viscosity index improver is a common type and is widely used in the fields of lubricants and…

CI-4/E7 Diesel Engine Oil Additive Complex is a high-performance lubricant additive designed specifically for diesel engines to improve engine efficiency, reduce wear, extend engine life and provide comprehensive engine protection. CI-4/E7 refers to a specific performance level for diesel engine oils established by the American Petroleum Institute (API). CI-4 specifications apply to heavy-duty diesel engines…

Extreme pressure additives, or EP additives, are lubricant additives specifically designed to protect metal surfaces under high pressure and temperature conditions. They form a protective film on metal surfaces that can withstand extreme pressure and prevent metal-to-metal contact, reducing wear and extending the life of gear components. Some common extreme pressure additives used in gear…

The specific additives used in lubricants may vary depending on the type of lubricant and its intended application. However, there are several common additives often used in lubricants to enhance their performance and provide additional benefits. These additives include: These are just a few examples of commonly used additives in lubricants. The specific combination and…
