Base Oil, also referred to as base stock, is a primary component used in the formulation of lubricants. It serves as the foundation or “base” upon which additives are blended to create various types of lubricating oils. Base oils are derived from crude oil through a refining process known as oil distillation or can be produced synthetically.
In summary, base oils are the foundation of lubricants and play a critical role in determining their performance. The classification of base oils into different groups allows for the selection of oils with specific characteristics to meet the requirements of different applications. Properties such as viscosity, VI, oxidation resistance, low-temperature fluidity, and stability are essential considerations when choosing a base oil. Additionally, compatibility with additives is crucial to ensure optimal performance and functionality of the final lubricant product.
