SF/CD Engine Oil Additive is an engine oil additive designed to improve engine performance and service life. SF/CD refers to the American Petroleum Institute (API) engine oil classification system. SF means that the additive is suitable for use on gasoline engines, and CD means that the additive is suitable for use on diesel engines. Such…

The CI-4/SL/CF-4 engine oil additive complex refers to a multi-grade, high-performance additive package designed to meet the requirements of both diesel (CI-4, CF-4) and gasoline (SL) engine oil specifications. This type of additive complex is widely used in multifunctional lubricants suitable for mixed fleet operations, where both gasoline and diesel engines (light-duty and heavy-duty) are…

In industrial production and machinery operation, lubrication is a vital link. Good lubrication can reduce friction and reduce wear, thereby ensuring the efficient operation of the machine. However, sometimes the lubrication effect may not be satisfactory. At this time, you need to consider using professional additives to improve the lubrication effect. Before using professional additives…

Viscosity is one of the most important physical properties of oil. It describes the resistance of oil to flow — essentially, how thick or thin it is. 🧪 Definition of Viscosity Viscosity is the measure of an oil’s internal resistance to motion or flow under applied force. 📏 Types of Viscosity in Oil 1. Dynamic…

When you think about lubricants, you probably don’t associate it with precious petroleum. However, the source of lubricants is what we know as petroleum. Compounds extracted from petroleum are carefully processed and blended to form the lubricants we use today. So, what exactly does this magical liquid contain? What is their respective function? This article…

With the rapid development of science and technology, chemicals are used more and more widely, among which zinc alkyl dithiophosphate is an important organophosphorus compound. Zinc alkyl dithiophosphates were selected as lubricant additives to provide antiwear and antioxidant properties to the base oil. Zinc alkyldithiophosphates are commonly used additives in engine and machinery lubricants. It…

Overbased calcium sulfonate is a type of additive commonly used in lubricants, particularly engine oils and greases, to enhance their performance, protection, and longevity. Overbased calcium sulfonate is formed by neutralizing sulfonic acid with calcium hydroxide, resulting in a highly alkaline and detergent-like compound. This unique chemistry provides several beneficial properties to lubricants, making it…

With the development of science and technology, many new technologies and products have been introduced into the automotive industry to improve vehicle performance and efficiency. Among them, the SP gasoline additive package has attracted the attention of many engine oil manufacturers. SP gasoline additive package is an efficient, environmentally friendly gasoline engine oil compound that…

Oil-based defoamers are a class of defoamers or antifoam agents used to control foam in oil-based systems. Foaming can occur in a variety of industrial processes, such as petroleum production, where stirring and aeration can lead to the formation of bubbles or foam. In many industries, foam can harm process efficiency and product quality. It…

Petroleum sulfonates are important compounds that play a vital role in the petroleum industry and in daily life. Petroleum sulfonates, also known as petroleum sulfonates or petroleum sulfonates, are a group of surfactants derived from petroleum or crude oil. They are produced by treating petroleum with concentrated sulfuric acid to form sulfonic acid, which is…
