Purpose and Specifications

WOLF OFFICIALTECH 75W140 LS GL 5 is a semi-synthetic transmission oil designed for heavy-duty hypoid differentials, axles, and manual gearboxes facing high shock loads, high torque at low speeds, and extreme temperatures from -40°C to over 150°C. Its 75W-140 viscosity grade flows smoothly in freezing cold for easy starts while staying thick under intense heat to protect gears from wear, extending component life up to 300,000 km or 3 years in compatible systems.

This limited-slip (LS) formula prevents chatter in differentials, ensures smooth power delivery, and resists oxidation for reliable performance in trucks, SUVs, and off-road vehicles.

When to Use / Replace?

• Use it in: Hypoid axles, final drives, and transfer cases requiring GL-5 LS specs, especially ZF, Scania, MAN, or Volvo drivelines under heavy loads or towing.
• Replace every: 100,000-300,000 km or 2-3 years, or sooner if operating in dusty, wet, or high-heat conditions to avoid gear scoring.
• Shelf life: 5 years unopened in cool, dry storage.
