Purpose and Specifications

WOLF EXTENDTECH 80W90 GL 5 is a tough mineral-based transmission oil built for heavy-duty gearboxes and hypoid axles. It handles high speeds, shock loads, and high torque at low speeds, keeping gears protected and shifting smooth even under extreme stress.

This 1L bottle meets top specs like API GL-5, ZF TE-ML 05A/07A/12E/16B/16C/17B/19B, MAN 342 M-1/M-2, and MIL-L-2105 C/D. It flows easily down to -33°C for cold starts and stays stable up to 210°C, reducing wear in trucks, tractors, and cars with manual transmissions or differentials.

• Protects hypoid gears and spiral bevels from extreme pressure
• Ensures easy gear changes and long gear life
• Ideal for agriculture, commercial vehicles, and off-road use

When to Use / Replace?

Use in manual gearboxes, rear axles, and transaxles calling for GL-5 oils. Perfect for high-load conditions like towing or heavy hauling. Replace every 60,000-100,000 km or 24-36 months, or sooner if you notice grinding noises, hard shifting, or fluid darkening. Shelf life is 5 years unopened in cool, dry storage.
