Mineral Base Oils N60

Mineral Base Oil N70 (also called SN 70 or 70N depending on refining process) is a light-to-medium viscosity paraffinic base oil derived from crude oil through solvent refining or hydrocracking. It is widely used as a base stock for lubricant formulations.

It offers:

• High purity (low sulfur & aromatics)
• Good oxidation stability
• Excellent blending characteristics

This makes it suitable for both automotive and industrial lubricants.
