Hemofluid Hypo 90 is a single-grade gear oil designed for the transmissions and differentials of vehicles and machinery where monograde lubricants are specified by the equipment manufacturer. This oil is recommended for applications operating in stable temperature conditions and steady operating regimes, where the consistent viscosity of a single-grade oil is preferred.

Hemofluid Hypo 90 is formulated to withstand medium to higher pressures and loads, making it suitable for a wide range of drivetrain applications that do not face extreme-pressure conditions. Its GL-4 performance level indicates that it provides adequate protection for spiral bevel, worm, and other gear types commonly found in manual transmissions and light-to-moderate duty differentials.

A notable feature of this oil is its high oxidation and thermal stability. This makes it particularly well-suited for operation in elevated temperature environments — whether from sustained high-speed driving, heavy-load operation, or warm ambient climates. The oil resists thermal breakdown and viscosity loss, maintaining its protective properties over extended service periods.

Additional benefits include effective anti-wear protection that extends gear and bearing life, reliable corrosion inhibition for internal metal surfaces, and good compatibility with common seal materials. Hemofluid Hypo 90 is used for lubrication of manual transmissions, differentials, and reducers in passenger cars, light delivery vehicles, commercial trucks, and off-highway equipment including road, construction, agricultural, and mining machinery. It is a proven, economical choice for applications where the manufacturer specifies single-grade gear oil, providing reliable drivetrain protection without the complexity of multigrade formulations.
