Purpose and Specifications

Castrol Transmax Axle EPX 80W-90 is a tough multipurpose gear oil designed for differentials, final drives, and axles in passenger cars, trucks, off-road, and farm equipment. It meets API GL-5 standards plus approvals like ZF TE-ML 05A/12E/16B/17B/19B/21A and MAN 342 M2, matching specs from Borg Warner, GMH, Ford, and Chrysler.

This oil delivers high load protection to shield gears from heavy stress, extending part life. Its strong film strength fights wear and shock loads, while excellent thermal stability prevents deposits and thickening in hot conditions up to 222°C flash point. It flows smoothly down to -26°C for reliable cold starts and pour point of -33°C.

• Protects under extreme loads in towing or hauling
• Stays effective from -30°C winters to 150°C+ operating temps
• 1L bottle perfect for service fills
