Mineral Base Oils N150

About Mineral Base Oils N150

Mineral Base Oil N150 is a light to medium viscosity base oil derived from the refining of crude petroleum. It belongs typically to Group I or Group II base oils, depending on the refining process (solvent refining or hydrocracking).

It is widely used as a primary raw material in lubricant formulations, offering a balanced combination of viscosity, solvency, thermal stability, and cost-effectiveness.

N150 provides good compatibility with additives and is suitable for producing a wide range of automotive and industrial lubricants, making it one of the most commonly used base oils globally.
