Synthetic base oil is a high-performance lubricant base made through chemical synthesis rather than refining crude oil, offering superior thermal stability, oxidation resistance, and low volatility compared to conventional mineral oils. It serves as the foundation for producing advanced engine oils, gear oils, hydraulic fluids, and compressor oils, providing enhanced lubrication, reduced wear, improved fuel efficiency, and extended equipment life. In India, synthetic base oils are widely used in automotive, industrial, and manufacturing applications, with suppliers offering different grades such as Group III, Group IV (PAO), and Group V (esters and other synthetics) to meet specific performance standards and operational requirements.
