Purpose and Specifications

MOTUL HD 80W90 Transmission Oil in 5L is a tough mineral-based gear oil built for heavy-duty mechanical transmissions, including synchronized or non-synchronized gearboxes, gearbox/differential combos, transfer boxes, and hypoid differentials without limited slip systems. It delivers extreme pressure protection to cut friction and wear, keeping gears safe under high loads, low speeds, or moderate loads at high speeds.

This oil flows smoothly at cold starts down to -27°C for easy shifting in winter, holds strong up to 210°C to resist breakdown in hot conditions, and maintains its 90 grade thickness after 20 hours of severe shear testing for long-lasting performance. Meets API GL-5 and GL-4 standards plus MIL-L-2105D for reliable protection in demanding applications.

• Key Benefits: Superior anti-wear shield, anti-foam, anti-corrosion, compatible with seals and yellow metals.
• Volume: 5 liters – perfect for full transmission fills or multiple services.
• Shelf Life: Up to 5 years unopened in cool, dry storage.

When to Use / Replace?

Use MOTUL HD 80W90 for trucks, off-road vehicles, or any transmission facing shocks, heavy loads, or high heat. Ideal when towing, hauling, or driving in extreme temps from -27°C to over 100°C operating range.

Replace every 40,000-60,000 km or 24-36 months under normal use, or sooner at 20,000-30,000 km for severe duty like frequent towing or off-roading – always check your vehicle's manual. Drain and refill while hot for best results.

FAQ

Q: Is this oil safe for my daily driver?
A: Yes, it's great for everyday use in non-limited slip transmissions, offering smooth shifts and gear protection even under load.

Q: Can it handle cold winters?
A: Absolutely, pours easily at -27°C to prevent hard shifting on frosty mornings.

Q: What's the difference from synthetic oils?
A: This mineral formula excels in high-pressure hypoid gears at a practical price, without needing premium synthetics for most applications.
