Base oils are the foundation of nearly every lubricant used in industrial and automotive applications. They help reduce friction, minimize wear, protect equipment, and improve overall operational efficiency.
What Are Base Oils?
Base oils are refined oils used to produce lubricants, hydraulic fluids, gear oils, compressor oils, and greases. Typically, they make up 70–95% of a finished lubricant, with additives added to enhance performance.
Types of Base Oils
The API classifies base oils into five groups:
Group I
Traditional mineral base oils used in general industrial applications.
Group II
Higher purity base oils with improved oxidation resistance and longer service life.
Group III
Highly refined base oils offering excellent performance and thermal stability.
Group IV
Synthetic PAO base oils designed for high-performance and extreme operating conditions.
Group V
Specialty base oils, including esters and other synthetic fluids for specialized applications.
Common Base Oil Grades
Widely used base oil grades include:
- SN 70
- SN 150
- SN 300
- SN 500
- Bright Stock
These grades are selected based on viscosity requirements and equipment operating conditions.
