Introduction

Mobile SHC 634 Oil and Mobile SHC 636 Oil are both high-performance synthetic lubricants designed for use in a variety of industrial applications. While they share some similarities, such as their synthetic base oils and advanced additive packages, there are also key differences between the two products that make them suitable for different types of machinery and operating conditions.

Viscosity

One of the main differences between Mobile SHC 634 Oil and Mobile SHC 636 Oil is their viscosity grades. Mobile SHC 634 Oil is a ISO VG 32 grade lubricant, while Mobile SHC 636 Oil is a ISO VG 68 grade lubricant. This means that Mobile SHC 634 Oil has a lower viscosity and is better suited for applications where low temperature start-up and high operating efficiency are important. On the other hand, Mobile SHC 636 Oil has a higher viscosity and is better suited for applications where high load carrying capacity and protection against wear are critical.

Temperature Range

Another important difference between Mobile SHC 634 Oil and Mobile SHC 636 Oil is their temperature range. Mobile SHC 634 Oil is designed to operate effectively in a wide range of temperatures, from -40°C to 150°C. This makes it suitable for applications where temperature fluctuations are common or where extreme temperatures are encountered. Mobile SHC 636 Oil, on the other hand, is designed to operate in a narrower temperature range, from -20°C to 120°C. This makes it more suitable for applications where consistent operating temperatures are maintained.

Load Carrying Capacity

Mobile SHC 634 Oil and Mobile SHC 636 Oil also differ in their load carrying capacity. Mobile SHC 634 Oil is formulated to provide excellent protection against wear and scuffing, making it ideal for applications where heavy loads are present. Mobile SHC 636 Oil, on the other hand, is designed to provide superior load carrying capacity and protection against micropitting, making it suitable for applications where shock loads and high contact pressures are common.

Oxidation Stability

When it comes to oxidation stability, both Mobile SHC 634 Oil and Mobile SHC 636 Oil excel. They are both formulated with advanced antioxidant additives that help extend oil life and reduce the formation of harmful oxidation by-products. However, Mobile SHC 636 Oil has been specifically designed to provide even greater oxidation stability, making it suitable for applications where extended oil drain intervals are desired.

Water Separability

Mobile SHC 634 Oil and Mobile SHC 636 Oil also differ in their water separability characteristics. Mobile SHC 634 Oil has good water separability properties, allowing water to be easily separated from the oil and preventing emulsion formation. Mobile SHC 636 Oil, on the other hand, has excellent water separability properties, making it ideal for applications where water contamination is a concern.

Conclusion

In conclusion, Mobile SHC 634 Oil and Mobile SHC 636 Oil are both high-performance synthetic lubricants that offer a range of benefits for industrial applications. While they share some similarities, such as their synthetic base oils and advanced additive packages, they also have key differences in terms of viscosity, temperature range, load carrying capacity, oxidation stability, and water separability. Understanding these differences is important in selecting the right lubricant for your specific machinery and operating conditions.
