Base Oil SN150 is a specific type of base oil that falls under Group I classification according to the American Petroleum Institute (API) categorization. SN150 refers to the viscosity range of the base oil, with “SN” standing for “solvent neutral” and “150” indicating the viscosity index. Let’s explore some key characteristics and applications of Base Oil SN150.
- Viscosity Range:
Base Oil SN150 has a viscosity range of approximately 100-250 centistokes (cSt) at 40°C. This viscosity range makes it suitable for a variety of lubricant applications where moderate to low viscosity is required.
- Composition and Production:
SN150 base oil is derived from crude oil through a refining process known as solvent refining or solvent extraction. It is produced by treating crude oil with a solvent to remove impurities, resulting in a refined base oil with improved stability and performance characteristics.
- Performance and Applications:
Base Oil SN150 is commonly used in a range of lubricant applications, including:
