Purpose and Specifications

WOLF EXTENDTECH 75W80 GL 5 5L is a tough transmission oil built for gearboxes facing extreme conditions like high speeds, heavy shock loads, and strong torque at low speeds. It delivers smooth shifting, cuts down wear for longer gear life, and resists breakdown to keep your transmission running strong.

This 75W-80 oil flows easily in cold starts down to -40°C and stays thick under intense heat, protecting hypoid gears, spiral bevel gears, worm wheels, and most transaxles. Meets API GL-5, MIL-L-2105 C, and MIL-L-2105 D standards for reliable performance in passenger cars and heavy-duty use.

When to Use / Replace?

Use this oil in manual transmissions and differentials under severe driving like towing, off-road, or high-mileage vehicles. Replace every 60,000-100,000 km or 3-5 years, or sooner if you notice rough shifting, grinding noises, or leaks. Shelf life is 5 years unopened when stored cool and dry.

Key Benefits:

• Smooth gear shifts even under load
• Protects against wear in tough conditions
• Longer oil life means fewer changes
