HIGHTEC TOPGEAR SAE 75W-90 is a high-performance, mineral-based gear oil specifically developed for use in heavily loaded axle drives, manual transmissions, and gear systems operating under demanding conditions. The formulation is designed to meet a wide range of international specifications and OEM requirements, ensuring reliable protection, long service life, and stable lubrication performance in both automotive and commercial vehicle applications.
This gear oil is characterized by its broad viscosity range, providing excellent lubrication behavior at low temperatures for smooth cold shifting while maintaining a stable and protective oil film at high operating temperatures. The balanced additive technology offers outstanding protection against wear, scuffing, and pitting, even under high torque, shock loads, and continuous heavy-duty operation. This helps to significantly extend the service life of gears, bearings, and other drivetrain components.
HIGHTEC TOPGEAR SAE 75W-90 meets the requirements of API GL-4 and API GL-5, making it suitable for a wide variety of hypoid gears, spiral bevel gears, and synchronized manual transmissions where dual-rated gear oils are specified. Compliance with MIL-L-2105D further confirms its suitability for severe-duty automotive and commercial applications.
The product demonstrates excellent resistance to oxidation and thermal degradation, preventing the formation of sludge and deposits while maintaining viscosity stability over extended drain intervals. Its corrosion-inhibiting properties protect steel and non-ferrous metals from rust and chemical attack, even in the presence of moisture and high operating stresses.
HIGHTEC TOPGEAR SAE 75W-90 is approved and recommended by leading manufacturers such as MAN, ZF, Volvo, and others, making it an ideal choice for mixed fleets operating across different vehicle brands and drivetrain configurations. It is also suitable for use in agricultural machinery, construction equipment, and off-road vehicles where robust and reliable gear lubrication is essential.
