Purpose and Specifications

MOTUL Motylgear 75W90 20L transmission oil is your go-to solution for noisy or hard-shifting gearboxes. This high-performance gear oil delivers extreme pressure protection for all mechanical transmissions, including synchronized and non-synchronized gearboxes, differentials, and transfer cases under heavy loads, shocks, or high speeds.

It meets API GL4 and GL5 standards, ensuring reliable lubrication from -45°C cold starts for smooth shifting to 200°C high-heat operation without breaking down. The 75W90 viscosity flows easily when cold for less gear lever effort, while staying thick at hot temps to cut noise, friction, and wear. Perfect for workshop bulk use with its 20-liter volume.

• Reduces gearbox noise and improves shifting
• Protects against wear in heavy-duty conditions
• Compatible with seals and yellow metals
• Anti-corrosion and anti-foam formula

When to Use / Replace?

Use Motylgear 75W90 in gearboxes operating under moderate to extreme loads, like trucks, off-road vehicles, or high-performance cars. Ideal for cold climates where easy cold shifts matter or hot conditions needing strong oil film.

Replace every 40,000-60,000 km or 24 months, or sooner if towing heavy loads or hearing noise. Follow your vehicle's manual, but this oil supports extended intervals thanks to its shear stability (less than 1.4% viscosity loss in tests). Shelf life is 5 years unopened in cool, dry storage.

FAQ

Is MOTUL Motylgear 75W90 safe for my differential?
Yes, it's approved for hypoid differentials without limited-slip systems, providing top anti-wear protection under high shock loads.

Can I use it in cold weather?
Absolutely, it pours at -45°C for smooth cold starts and easy gear changes, even below freezing.

How much for a full gearbox change?
A typical car gearbox takes 2-3 liters; this 20L pail covers multiple services or larger truck transmissions.
