Purpose and Specifications

Motul Motylgear 75W-90 transmission oil (109057) is a semi-synthetic gear oil designed for all mechanical transmissions, including synchronized or non-synchronized gearboxes, differentials, and transfer cases. It meets API GL-4/GL-5 and MIL-L-2105D standards, providing strong protection against wear, corrosion, and oxidation under heavy loads, shocks, or high speeds.

This 5-liter container delivers high lubricating power that reduces friction and wear, while staying thick at hot temperatures up to 150°C for reliable oil film strength. Its fluidity at low temperatures down to -51°C makes gear shifting smooth and easy, even in cold weather, requiring less effort on the gear lever.

• Volume: 5 liters in a sturdy canister
• Suitable for: Manual gearboxes, hypoid differentials (without limited slip), operating from -40°C to 150°C
• Practical benefits: Quiets noisy gearboxes, eases hard shifting, extends transmission life

When to Use / Replace?

Use Motul Motylgear 75W-90 in vehicles with manual transmissions experiencing noisy operation or stiff shifting, or during routine maintenance. Replace every 60,000 km or 3 years under normal driving; every 30,000 km or 18 months for heavy-duty, towing, or racing use. Shelf life is 5 years unopened when stored cool and dry.

FAQ

Is this oil good for cold weather starts? Yes, it flows easily down to -51°C, making gears shift smoothly without extra force even when cold.

Can I use it in my differential? Absolutely, it's perfect for hypoid differentials without limited slip systems, protecting under high loads and heat.

How much for a full gearbox change? Typically 2-3 liters for most cars; this 5L fills larger transmissions or allows complete flushes.
