Astrol EP 85W-140 Manual Transmission and Differential Oil
Vehicle transmission and differential systems operate continuously under high pressure, friction, and extreme temperatures. Especially in manual transmission and heavy-duty vehicles, using a high-quality gear oil is critical to prevent metal-to-metal contact between gears and to ensure long-lasting performance. Astrol EP 85W-140 Transmission and Differential Oil protects transmission, axle, and differential gears with its Extreme Pressure (EP) additives. Optimized for both commercial vehicles and heavy machinery, this oil delivers high-temperature resistance, stable viscosity, and superior protection.
Wear and Tear Protection
Thanks to its EP additives, Astrol EP 85W-140 minimizes metal-to-metal contact in differential and transmission gears, significantly extending gear life in both manual transmissions and heavy-duty axles. Differential and transmission systems are frequently exposed to sudden torque changes and heavy load conditions. With its high-pressure-resistant formula, this oil ensures dependable performance even in demanding environments.
Metal components can corrode due to moisture, water, and condensation. The EP-enhanced formula helps protect differential and axle components against corrosion, supporting long-term durability.
With its SAE 85W-140 viscosity grade, this oil maintains fluidity at low temperatures while forming a strong protective film at high temperatures. This balance ensures safe and consistent performance throughout the year. By reducing metal contact within transmission and differential systems, it limits wear and enhances mechanical efficiency.
Its pressure-resistant formulation provides reliable lubrication even during sudden torque variations and heavy load conditions. Advanced additive technology also helps prevent the formation of sludge, deposits, and residue on gears, enabling transmission and differential systems to operate cleanly and efficiently. The 85W-140 viscosity delivers sufficient flow in cold conditions while maintaining a durable oil film in high temperatures, ensuring optimal protection across harsh climates and working environments.
From the perspective of Alef Grup, Astrol EP 85W-140 Transmission and Differential Oil also contributes to quieter system operation. By reducing friction between gears, it minimizes energy loss and improves overall system performance. This advantage supports high performance not only in passenger vehicles but also in heavy-duty trucks, construction equipment, and off-road vehicles. Its multi-purpose structure allows compatibility with various vehicle types while helping reduce maintenance costs. With regular use, transmission and differential life are extended, system efficiency reaches optimal levels, and fuel savings can be achieved.
Astrol EP 85W-140 offers a wide range of applications—from passenger cars to trucks and heavy machinery. It can be safely used in manual transmissions, differentials, and axle systems. Delivering superior performance even in off-road vehicles and demanding operating conditions, it provides vehicle owners with long-term protection. Compliance with API GL-5 and other manufacturer-approved standards further guarantees system reliability and durability.
