Purpose and Specifications

MOTUL GEAR COMPETITION 75W140 is a 100% synthetic ester-based racing transmission oil designed for high-performance gearboxes and hypoid differentials with limited-slip systems. It delivers unbeatable protection under extreme conditions like track racing, rallies, or heavy loads, staying thick up to 140 viscosity at hot temperatures over 100°C while flowing smoothly at cold starts below 0°C for easy shifting.

• Zero shear loss: Maintains thick oil film even after 20 hours of extreme stress, preventing metal-on-metal contact.
• Superior lubrication: Cuts friction and wear, extending gearbox life in race cars like Nissan 350Z or Subaru models.
• Quiet operation: Built-in friction modifiers eliminate noise and dragging in limited-slip diffs.
• API GL-5 rated: Exceeds standards for extreme pressure protection, safe for seals and yellow metals.

1L bottle perfect for differentials needing 1.4L (like Nissan 370Z) – use two for a full change.

When to Use / Replace?

Use this oil in racing vehicles, rally cars, or modified street cars with integrated limited-slip differentials under shocks, heavy loads, or high speeds. Ideal for gearboxes running hot over 100°C or cold mornings where smooth shifts matter.

• Replace every 10,000-20,000 km or annually for track use; follow manufacturer intervals for street driving and adjust based on harsh conditions.
• Shelf life: 5 years unopened in cool, dry storage.
