Composite additives for oil products refer to additives that are composed of two or more additives with different functions mixed in a certain proportion. The main purpose of adding complex additives to oil is to improve the performance of the oil to meet the needs of practical applications. This article will introduce the functions, types,… Read more

In today’s highly developed transportation system, oil additives have become an indispensable part. So, what exactly are oil additives? What is its function? Oil additives play an important role in the petroleum refining and oil manufacturing processes. First of all, it can improve the quality of oil and ensure the normal operation of the engine.… Read more

The pour point of oil is the lowest temperature at which the oil can flow or pour. It is an important parameter in evaluating the low-temperature performance of lubricants, especially in applications where cold weather or sub-zero temperatures are encountered. If the oil has a high pour point, the oil has poor low-temperature properties and… Read more

When determining viscosity, VG refers to “viscosity grade.” A viscosity grade is a numerical classification system used to measure and compare the viscosities of lubricants, especially oils. It is usually represented by a numerical code such as VG 32 or VG 68. VG systems are commonly used in industrial applications such as hydraulic systems, transmissions… Read more

When selecting engine oil, viscosity grade is an important consideration. Among them, what role does W level play? In viscosity grades, the term “W” stands for “winter.” It is the name used to indicate the low temperature viscosity properties of an oil, primarily used in engine oils. “W” indicates that the oil meets low-temperature performance… Read more

Lowering the pour point of a lubricant improves its flow characteristics at low temperatures—crucial for cold-weather performance and machinery startup. Here’s a detailed overview of solutions and implementation strategies to reduce pour point effectively. 🧊 What is Pour Point? ✅ Solutions to Lower Pour Point 1. Pour Point Depressants (PPDs) Implementation Tips: 2. Use of… Read more

The water in hydraulic oil mainly comes from moisture in the air and condensation water generated by the hydraulic equipment itself. This moisture will reduce the quality of the hydraulic oil, lead to reduced equipment performance, and accelerate wear and corrosion of hydraulic components. In order to ensure the stable operation of hydraulic equipment, measures… Read more

Viscosity is a measure of a substance’s resistance to flow. To change the viscosity of a substance, such as oil, you can implement the following methods: Each substance may respond differently to these methods, so it is crucial to consider the specific substance and its behavior when trying to change its viscosity. Read more

Reducing the viscosity of engine oil means making it thinner—i.e., flow more easily—especially at low or high temperatures. This is often done for fuel economy, cold-start performance, or adapting to engine design requirements. 🔧 Ways to Reduce Engine Oil Viscosity 1. Use a Lower Viscosity Base Oil 2. Add Diluent Base Oil 3. Use Pour… Read more
