Group II Base Oils
Base oils are the main ingredient in lubricants, and they play a big role in helping machines run smoothly. They reduce friction, prevent wear, and control heat inside engines and equipment. The quality of the base oil directly affects how well the lubricant performs, making it a key factor in keeping machines efficient and long-lasting.
Group II base oils come from crude oil but go through an extra process called hydrofinishing. This process uses hydrogen to clean and improve the oil. Because of this, Group II oils are purer and perform better than Group I oils.
Advantages of Group II Base Oils
- Higher Viscosity Index: Group II oils can handle heat better. With a viscosity index of up to 120, they give smoother lubrication even at high temperatures.
- Less Aromatic Content: These oils have fewer aromatic compounds (less than 10%), which means they stay more stable when heated and don’t evaporate easily.
- Lower Sulfur Level: Group II oils have very little sulfur, which helps protect engines from rust and oxidation. This makes them cleaner and longer-lasting.
Production of Group II Base Oils
Group II base oils are made using a process called hydrocracking. This process is more advanced than the one used for Group I oils. In hydrocracking, the oil is treated with hydrogen under high heat and pressure.
This removes more dirt and unwanted materials, making the oil cleaner and stronger. A special catalyst helps break down large oil molecules into smaller, more useful ones. Because of this process, Group II oils have less sulfur and more saturated molecules, which makes them more stable and long-lasting.
Characteristics of Group II Base Oils
Group II base oils are known for being cleaner and more stable than Group I oils. They have a high saturation level and very low sulfur content. Their viscosity index usually ranges from 80 to 120, which means they can perform well in both hot and cold conditions. These oils resist oxidation better, so they don’t form sludge or lose quality easily.
Their low volatility means they don’t evaporate quickly, helping engines run smoother for longer. Overall, Group II base oils offer a great balance of performance and cost, making them suitable for many types of lubricants.
Thermal and Oxidative Stability
For engine oils, it’s important to stay strong under heat and resist breaking down. Group II base oils are excellent at this. They have high thermal and oxidative stability, meaning they can handle high temperatures without losing quality.
This helps prevent sludge, acid buildup, and engine damage. These strong properties come from the hydrocracking process, which fills the oil with hydrogen and removes impurities. As a result, Group II oils last longer and protect engines better, even in tough conditions.
Applications of Group II Base Oils
Group II base oils are widely used to make engine oils, transmission fluids, and other lubricants for both cars and industrial machines. Because they can handle high heat and don’t evaporate easily, they work great in high-performance engines and heavy-duty equipment.
Their wide viscosity range and strong resistance to oxidation make them useful for many types of products. Since they already perform well, they need fewer additives, which helps lower the overall cost. That’s why Group II base oils are a popular choice for both quality and affordability.
Environmental and Regulatory Considerations
Group II base oils are also better for the environment. They produce fewer emissions and waste because they are more stable and don’t evaporate as quickly as Group I oils. Many global regulations now focus on reducing pollution and promoting cleaner products, so companies are switching to more eco-friendly lubricants.
Group II base oils meet these standards well because they are made through a cleaner refining process and help create oils that are safer for the planet.
Primary Refining Techniques for Group II Base Oils
Group II base oils are mainly made through a process called hydrocracking. In this process, crude oil is treated with hydrogen gas under high pressure and temperature. This breaks down large hydrocarbon molecules and removes impurities.
The result is a purer, more stable oil with better performance and longer life. This advanced refining method is what makes Group II base oils stronger and cleaner than Group I oils.
Group II Base Oils: Top Picks at a Glance
N500
N500 Group II base oils are expertly refined through hydrocracking, a process that removes impurities and boosts performance. These oils are built to handle heat, oxidation, and heavy loads while keeping machines running smoothly.
With a high viscosity index (80–120) and low sulfur content, they deliver long-lasting stability and efficiency. Perfect for engines, gears, marine systems, and industrial equipment, N500 oils help parts last longer and perform at their best.
N150-100
N150-100 is a high-quality Group II base oil made through advanced hydrocracking technology for cleaner, stronger performance. It offers excellent oxidation control, keeps the oil’s thickness stable, and helps reduce engine wear for longer life.
When blended with a small amount of additives, it becomes the perfect base for engine oils, power transmission fluids, and lubricating waxes. Designed for efficiency and durability, N150-100 keeps machines running smoother for longer.
How Does the Viscosity Index of Group II Base Oils Affect Their Use?
Group II base oils usually have a viscosity index between 80 and 120. This number shows how well the oil can handle temperature changes. A higher viscosity index means the oil stays smooth — it won’t get too thin when it’s hot or too thick when it’s cold.
Because of this, Group II oils work well in both hot and cold weather, making them great for all kinds of engines and machinery.
Market Trends and Future Outlook
The Group II base oil market is growing fast as technology improves and industries look for cleaner, more efficient lubricants. More companies now prefer oils that protect engines better and are friendly to the environment.
New hydrocracking methods and advanced additives are helping make Group II oils even stronger and more reliable. As industries focus on high performance and sustainability, Group II base oils are expected to play an even bigger role in the future.
Which Synthetic Oil is Right for You?
Choosing the right synthetic oil depends on your engine and how you use it. For everyday driving, Group III oils offer a great mix of performance and affordability. If you want top protection and better performance in extreme temperatures, go for PAO-based or ester-based synthetic oils—they’re made for tougher conditions.
For motorcycles, ester or PAO-based oils are ideal since they handle high RPMs and heat with ease. And if you drive a heavy-duty diesel truck, you’ll need a stronger oil that can handle long hours and heavy loads—PAO and advanced Group III oils are perfect for that.
At Fubex Lubricants, we offer a full range of premium synthetic oils designed to deliver maximum protection, cleaner engines, and longer performance life—no matter what you drive.
