When standard gear oils fail under pressure, Motul Gear Competition 75W140 steps in. Developed with advanced Ester Core Technology, this 100% synthetic transmission oil is engineered for high-performance gearboxes, transfer cases, and differentials – including limited-slip (LSD) units – operating in the most demanding racing environments.

Built for Extreme Conditions

Designed for motorsport applications, this oil delivers exceptional resistance to shear, ensuring stable viscosity even under extreme loads and temperatures. The high-strength oil film maintains maximum protection, reducing friction and minimizing wear across critical drivetrain components.

• outstanding load resistance under track conditions
• reduced friction and improved drivetrain efficiency
• enhanced durability for high-performance builds

Proven in Motorsport

Trusted by professional racing teams and used in top-tier competitions, Motul Gear Competition 75W140 meets and exceeds key industry standards:

• API GL-5
• Approved by MUGEN (24H Le Mans)
• Used by HEWLAND, X-TRAC, Japanese GT teams

This is a fluid designed not just to perform – but to win.

Thermal Stability & Smooth Operation

The SAE 140 high-temperature viscosity ensures a strong and stable oil film under extreme heat, protecting gears during prolonged high-load operation. At the same time, its low-temperature fluidity guarantees smooth gear engagement from cold starts.

• consistent performance at extreme temperatures
• improved gearbox noise reduction
• precise and smooth shifting feel
