Purpose and Specifications

LIQUI MOLY 1408 75W-90 TS is a high-performance semi-synthetic hypoid gear oil designed for manual transmissions and differentials. This 20-liter canister delivers exceptional protection for gears under heavy loads and extreme conditions, ensuring smooth shifting and minimal wear. Its 75W-90 viscosity flows easily in cold starts down to -40°C and stays thick at high operating temps up to 150°C, providing reliable lubrication across temperature swings.

Key benefits include outstanding ageing stability for long service life, excellent wear resistance that extends gear lifespan, and reduced friction for quieter operation and better fuel economy. Meets API GL4 standards, ideal for vehicles from VW, Ford, Audi, and heavy-duty applications like trucks from DAF, MAN, and Scania.

When to Use / Replace?

• Replace every 60,000-100,000 km or 3-5 years under normal driving; sooner (every 40,000 km) for towing, off-road, or severe conditions to prevent gear damage.
• Use in manual transmissions, transaxles, and hypoid axles experiencing hard shifts, noise, or operating in hot climates (above 40°C) or freezing winters.
• Shelf life: 5 years unopened in cool, dry storage; check fluid color and smell before use.
