Purpose and Specifications

MOTUL Gear Competition 75W-140 (103995) is a premium synthetic ester-based transmission oil in a 20-liter tank, perfect for high-performance racing vehicles like those in speedway, rally, and raid. It delivers very high lubricating power to cut friction and wear, while the 140 grade at hot temps keeps a tough oil film intact under extreme loads up to 150°C, preventing breakdowns and noise.

Key perks include 0% shear loss for an unshearable film in harsh conditions, built-in friction modifiers to quiet limited-slip differentials (LSD), and top anti-wear protection that shields gears from scuffing and pitting. Flows easy when cold for quick startups, stays thick when hot for reliable shifting.

When to Use / Replace?

Use in all hypoid differentials with LSD, racing gearboxes, and heavy-duty transmissions. Ideal for track days, off-road raids, or high-heat towing. Replace every 30,000 km or 24 months in racing, or 60,000 km/36 months in street use - check fluid color and level monthly. Shelf life is 5 years unopened, stored cool and dry.
