A true grease consists of an oil or other fluid lubricant that is mixed with a thickener, typically a soap, to form a solid or semisolid. Greases are usually shear-thinning or pseudo-plastic fluids , which means that the viscosity of the fluid is reduced under shear stress .
Sodium grease is formulated by mixing soda soap with additives and base oils. Such mixture provides solid shear stability, high dropping point, excellent rust protection, and good lubrication, but has poor water resistance and oxidation stability.
The two main types of lubricants are oils and greases. Both aim to lubricate equipment and prevent damage through metal to metal contact. However, there are a few key differences in how they are used. To put it simply, grease is oil mixed with a thickener and other additives.
It's important to know when to use oil or grease, as each has its own advantages and applications. In this article, we explore the differences between oil and grease, how grease is made, considerations for choosing the right lubricant, and when to use oil instead of grease.
Grease lubricant, in its simplest form, is a semi-solid lubricant composed of a lubricating fluid (typically a base oil) and a thickening agent (thickener) that holds the lubricating fluid in place, preventing it from leaking or dripping away from the application.
Extreme temperature grease with synthetic base oils and a blend of Molub-Alloy lubricating solids selected for high temperature service, such as paint drying ovens. Castrol offers a comprehensive range of world-class greases to provide advanced protection for your equipment.
Grease vs. Oil What's the Difference? Grease and oil are both lubricants commonly used in various industries and applications. However, they differ in their composition and properties. Grease is a semi-solid substance made by mixing oil with a thickening agent, such as soap or clay.

The function of grease is to remain in contact with and lubricate moving surfaces without leaking out under the force of gravity, centrifugal action or being squeezed out under pressure. Its major practical requirement is that it retains its properties under shear forces at all temperatures it experiences during use.
Lubricating greases are a mixture of oil, a thickener, and various additives. Greases are known for their ability to stay in place and provide excellent leakage control. They form a protective seal against contaminants, preventing particles and water from entering critical components.
