What Makes SN150, SN500, and SN600 Ideal for Lubricant Formulations?
Base oils are the foundation for most lubricants, and their performance has a direct influence on the efficiency, performance, and longevity of machinery and engines. Among the many base oil groups, SN150, SN500, and SN600 solvent neutral (SN) mineral oils are favorites due to the cost-performance flexibility balance they provide. They are Group I base oils, manufactured by solvent extraction, dewaxing, and hydrotreating processes to achieve the desired level of purity and quality.
All of these grades have a unique viscosity profile and hence are suitable for various lubricant blends. SN150 is a low-viscosity light base oil suitable for use in situations where there will be rapid flow and rapid heat dissipation. SN500 has medium viscosity and hence is extremely compatible with automotive and industrial lubricants. SN600, being of high viscosity, possesses good film strength and protection in situations of heavy load and high temperatures.
Their oxidative stability, nice pour points, and blending ease with additives make them all the more desirable for application to lubricant manufacturing. Together when blended or blended individually, uses for base oils SN150, SN500, SN600 cover a wide range of industries from automobiles to heavy equipment and they are an essential requirement for application in lubricant manufacturing.

Role of Base Oils in the Automotive and Heavy Machinery Industry
The automotive and heavy mobile equipment industries consume the largest volume of lubricants and, especially, rely on base oils (e.g. SN150, SN500, SN600) for performance, durability, and protection when formulating lube engine oils and oils and fluids for transmission, axles, and gears.
In the automotive application, SN150 is used in typical/some low viscosity formulations where low-temperature fluidity is important. This is true for light-duty engine oils (0W-20 values) and transmission fluids that call for low-vis environment. With SN500 as a middle tier, typically multi-grade engine oils and gear oils provide the advantages of fluidity and film strength as a mid-range or multi-range oil. SN600, with its higher viscosity and excellent load bearing, offering protection for gearboxes, axles, and equipment subject to extreme pressure and heat.
In heavy mobile equipment (e.g. excavators, dozers, and mine trucks), base oils help lubricate equipment for long operating hours, reduce wear and wear rates, and resist thermal, or heat breakdown. The uses of base oils in heavy machinery and engine oils and oils and fluids for gears, transmission, and axles, is largely driven by the demanding and diverse uses for hydraulic oil and lubricants subjected to extreme pressures and severity. Having reliable lubrication is designed to maximize a production cycle allowing extended uptime and prolonged equipment life.

How SN150 Is Used in Transformer Oils and Hydraulic Fluids
SN150, a light and low-viscosity base oil, plays a vital role in the formulation of transformer oils and hydraulic fluids, where cleanliness, stability, and fluid performance are crucial. In electrical applications, SN150 serves as a base for transformer oils, which must possess excellent dielectric strength, low moisture content, and thermal stability. Its naturally low viscosity allows efficient heat transfer and cooling within transformers, preventing overheating and electrical breakdowns.
In hydraulic systems, SN150’s excellent flow properties at low temperatures ensure fast system response and minimal energy loss, especially in mobile or industrial equipment operating in cold environments. Its chemical stability and compatibility with various additive packages allow it to perform reliably under pressure without oxidizing or foaming.
Whether in the energy or industrial sectors, the uses for base oils SN150, SN500, SN600 are tailored to performance-specific demands. SN150, in particular, is a go-to choice where precise, clean, and thermally stable lubrication is essential for sensitive systems.
Applications of SN500 in Engine Oils and Industrial Lubricants
Currently, the mid-range viscosity base oil finds its main use for manufacturing engine oils, compressor oils, and general industrial lubricants. It is a mostly mid-range base oil because of its viscosity, which aids in the formulation of monograde and multigrade engine oils. Such oils may need to strike a balance between flow and oil film protection in areas with similar necessary conditions. The higher stability against oxidation and thermal degradation that gives SN500 a plus means better performance during high operating temperatures and under prolonged usage.
In the industrial sector, use of SN500 can be seen for hydraulic fluids, gear oils, and turbine lubricants and those working under mild load and temperature conditions. Compatible with additive systems, it improves properties such as anti-wear, corrosion-resistance, and detergent action imparted to the lubricant, thereby promoting the longevity of the equipment and increasing intervals between maintenance.
All this versatility and moderately good performance makes SN500 an inevitable automotive and industrial lubricant manufacturing product. In the base oil utilization field, especially applications requiring resilient lubrication and viscosity control, SN500, along with SN150 and SN600, stands out as a trusty workhorse.
Why SN600 Is Preferred for High-Viscosity Lubricant Needs
For applications that need thicker oil films and heavy load carrying ability, then SN600 is the base oil of choice. In fact, its viscosity makes it ideal to create lubricants that are used in the latest heavy duty gearboxes, industrial bearings and also marine engines where parts are subjected to large forces, high temperatures and slow speeds.
What advantages does it have? SN600 has a robust lubricating film that resists metal to metal contact under heavy load. It also provides high resistance to wear and tear under these conditions which ultimately increases the life of your equipment. In addition, its thermal breakdown resistance will help to prevent viscosity changes under high temperatures when you are on the job and running the equipment at elevated temperatures in industrial and marine applications.
SN600 also provides a degree of tackiness which helps in adhesion properties of the lubricants that are being created, especially useful in open gear greases, railway axle oils and marine cylinder oils. When compared to other base oils SN150, SN500 and SN600, the most useful and useable in terms of high load situations while providing a high degree of protection, reduced leakage and long lasting performance under extreme working conditions, is SN600.

Base Oils in Metalworking: From Cutting Fluids to Rust Prevention
In metalworking, the choice of base oil directly affects machining performance and equipment protection. SN150 is often selected for cutting fluids and soluble oils, where its low viscosity and excellent wetting properties ensure efficient heat removal and chip evacuation. Its superior cleanliness minimizes varnish and deposit formation on precision tools.
For straight oils and neat cutting fluids, SN500 delivers a balanced film strength and viscosity, enhancing tool lubrication and surface finish. Meanwhile, SN600 is ideal for heavy-load applications such as draw‐bench oils and gear cutting, where its thicker film prevents metal-to-metal contact under high pressure.
Beyond cutting, all three grades play roles in rust prevention. Their natural solvency and compatibility with rust-inhibitor additives protect machined parts and stored components from corrosion. The uses for base oils SN150, SN500, SN600 in metalworking span from precision machining to long-term corrosion control, ensuring both efficiency and part longevity.
The Importance of Base Oil Purity and Viscosity in Industrial Performance
In industrial lubrication, purity and viscosity are critical for consistent performance. High-purity base oils like SN150, SN500, and SN600 contain fewer contaminants, reducing oxidation and extending oil life. This results in cleaner operation, lower maintenance, and better protection for machinery.
Viscosity determines how the oil behaves under heat and pressure. SN150 provides low resistance and quick circulation, SN500 offers a balance between flow and protection, while SN600 maintains a thick film for high-load applications.
When selecting lubricants, industries rely on oils that can perform under stress. The uses for base oils SN150, SN500, SN600 are closely tied to how well they balance these two essential qualities for safe, efficient operations.
