Servo Gear TH 80W-90 is a high-performance automotive gear oil designed to deliver superior protection and efficiency in mechanical transmissions, hypoid gear systems, and differential units operating under extreme pressure conditions. It is formulated from specially selected high-viscosity index base oils combined with advanced anti-wear, anti-rust, and oxidation-resistant additives to ensure consistent performance in demanding environments. This multi-purpose gear lubricant provides exceptional film strength and thermal stability, maintaining its protective properties even at bulk oil temperatures reaching up to 150°C. The superior extreme pressure characteristics of Servo Gear TH 80W-90 offer excellent protection against gear wear and pitting, while its high oxidation resistance prevents sludge formation, ensuring a longer oil and component life. It also exhibits strong corrosion protection, guarding transmission assemblies against rust and oxidation during extended service periods. With excellent viscosity control, it guarantees smooth gear shifting, improved torque transmission, and stable performance across a wide temperature range. Recommended primarily for Tata Hitachi excavators and similar heavy-duty vehicles, this oil meets the rigorous service requirements of API GL-5 and IS 1118:1992 Type GL-5 specifications, making it suitable for modern transmission systems that demand high reliability and long-lasting durability
