This combination creates a product with excellent chemical and thermal stability over a wide range of temperature. It provides first class performance under high pressure or EP conditions by utilizing the core sulfur-phosphorus EP technology. It is also blended with group 3 oil and antifoam to suppress excess forming and to provide greater stability between oil particles, hence prolong the life span of the gear oil.
