Famhipo 90 EP is a mineral-based single-grade gear oil formulated for the lubrication of hypoid and other gear transmissions in motor vehicles, construction equipment, and agricultural machinery operating under the most severe conditions. This GL-5 quality level oil provides maximum extreme-pressure protection for heavily loaded drivetrain components.

The GL-5 performance level contains a higher concentration of extreme-pressure (EP) additives compared to GL-4 oils, providing superior protection for hypoid gear sets where the sliding action between gear teeth creates extremely high contact pressures. Under these demanding conditions, the EP additives form a protective chemical boundary film that prevents metal-to-metal contact, gear tooth welding, and scuffing, even under sustained heavy loads and shock loading.

The SAE 90 monograde viscosity provides a strong, consistent oil film suited for operation in stable and warm temperature conditions. At operating temperature, the oil maintains robust film strength that effectively protects heavily loaded gears, bearings, and other drivetrain components from wear.

Key performance benefits include outstanding extreme-pressure protection for hypoid, spiral bevel, and other gear configurations, excellent thermal stability that resists oil degradation during demanding service, reliable corrosion protection for internal components, and effective foam resistance. Famhipo 90 EP is recommended for differentials, final drives, and other heavy-duty gear applications in trucks, buses, 4WD vehicles, construction equipment, and agricultural machinery where the manufacturer specifies GL-5 performance. It is a proven, economical choice for drivetrain applications that face the most severe load, speed, and temperature conditions encountered in commercial and off-highway operations.
