HP Powerglide C-4 30 is a premium-quality transmission oil formulated specifically to meet the stringent requirements of Allison C-4 service classification. Designed for modern automatic transmissions, torque converters, and power-shift systems used in heavy-duty commercial and industrial machinery, this oil ensures reliable performance, superior protection, and long-lasting operational stability under severe working conditions. Manufactured from highly refined base oils blended with advanced oxidation inhibitors, anti-wear agents, and friction modifiers, HP Powerglide C-4 30 delivers exceptional thermal stability and resistance to high-temperature degradation. Its balanced formulation provides excellent lubricating film strength that prevents metal-to-metal contact, minimizes wear, and ensures smooth, efficient transmission performance even in high-load and continuous operation environments. This oil exhibits superior oxidation control properties, helping to prevent the formation of harmful sludge, varnish, and carbon deposits, which can otherwise affect the efficiency of transmission components. The product’s outstanding high-temperature performance maintains fluid consistency and protects vital parts from breakdown, ensuring extended oil life and reduced maintenance costs. HP Powerglide C-4 30 also offers excellent anti-foam characteristics and rapid air release properties, preventing cavitation and ensuring smooth hydraulic performance. Its corrosion-resistant and anti-rust additives protect metal surfaces against moisture and chemical deterioration, making it suitable for a wide range of climate and working conditions. The oil’s controlled frictional behavior ensures smooth gear shifting and precise power transmission, optimizing equipment reliability and productivity. With a kinematic viscosity range of 9.3 – 12.5 cSt at 100°C, flash point of 220°C (COC), and pour point of -21°C, HP Powerglide C-4 30 demonstrates remarkable stability and flow properties even under temperature variations. It also achieves a Copper Strip Corrosion rating of 1 (at 100°C for 3 hours), indicating excellent material compatibility and non-corrosive behavior in transmission systems. HP Powerglide C-4 30 is recommended for all commercial power-shift transmissions, industrial torque converters, and automatic transmission systems requiring Allison C-4 specification oils. It is suitable for use in off-highway construction machinery, mining equipment, and heavy-duty vehicles where dependable performance and long service intervals are essential. Engineered for durability, reliability, and efficiency, HP Powerglide C-4 30 ensures smooth power transfer, protects transmission components from wear and oxidation, and extends the operational life of industrial and automotive transmission systems.
