Purpose and Specifications

MOTUL Motylgear 75W-90 Transmission Oil (104000) is a premium semi-synthetic gear oil designed for manual gearboxes, differentials, and transfer cases. This 20-liter drum delivers exceptional protection under heavy loads and high temperatures up to 150°C, while staying fluid down to -30°C for smooth cold starts.

It reduces gear noise, prevents wear, and maintains consistent performance for 60,000-100,000 km or 3-5 years, depending on driving conditions. The Technosynthese formula provides superior film strength that resists breakdown, ensuring quieter shifts and longer component life in cars, trucks, and heavy-duty vehicles.

When to Use / Replace?

• Hard-shifting or noisy gearboxes: Use when gears grind or whine, especially under load – this oil quiets operation immediately.
• Heavy-duty applications: Ideal for towing, off-road, or high-mileage vehicles operating in extreme temps from -30°C to 150°C.
• Replacement schedule: Change every 60,000 km or 36 months for normal use; every 30,000 km or 24 months for severe conditions like frequent towing. Shelf life is 5 years unopened.
