Overview
Base Oil SN 150 is a light neutral base oil obtained from solvent refining and dewaxing of paraffinic crude. It is classified as a Group I base oil and serves as a primary feedstock in the formulation of lubricants, engine oils, and specialty industrial fluids. Its balance of viscosity, oxidation stability, and solvency makes it widely used across automotive and industrial lubricant applications.
