Top Applications of SN150 Base Oil in Automotive and Industrial Lubricants

Base oil SN150, a solvent-refined Group I mineral oil, is a versatile and cost-efficient foundation for many automotive and industrial lubricant formulations. From engines to hydraulic systems and metalworking fluids, SN150’s balanced viscosity, solvency, and thermal stability make it a go-to base oil grade for formulators worldwide.

 1. Engine Oils & Transmission Fluids

In automotive lubrication, SN150 is commonly used in engine oils, gear oils, and transmission fluids. Its moderate viscosity index (typically around 90–100) and low volatility (Noack) provide reliable lubrication for crankshafts, bearings, and camshaft components across a broad temperature range. Its fuel economy benefits and oxidative stability make it a preferred choice for light-duty formulations.Peak Universal 

 2. Industrial Hydraulic and Turbine Oils

SN150 is excellent in hydraulic systems, compressor oils, and turbine lubricants. Its thermal resilience and low pour point (around –6 °C to –9 °C) allow smooth performance in both hot and cold industrial environments, minimizing wear and extending service life.

 3. Metalworking and Cutting Fluids

Base oil SN150 serves as a reliable base for metalworking fluids used in cutting, grinding, and machining operations. Thanks to its strong solvency and film-strength characteristics, it promotes better tool life, machining precision, and surface finish

 4. Grease & General-Purpose Lubricants

Grease production often relies on SN150 as its base: it blends well with thickeners and additive packages, forming greases suitable for bearings, general machinery, and industrial equipment. Its compatibility with other additives makes formulation flexible and cost-effective.danalubes.comGars Lubricants

 5. Specialty Applications: Process Oils & Additive Carriers

SN150 is also used as a process oil or carrier in rubber, adhesives, polymer masterbatches, and agrochemical formulations. It dissolves additives consistently and aids in manufacturing stable end-products like rubber compounds and emulsions.danalubes.comPeak Universal Business
