Description

When it comes to protecting high-performance transmissions under extreme stress, not all gear oils are built the same. This Motul synthetic gear oil is specifically engineered for racing gearboxes and high-load mechanical transmissions where durability, consistency, and shift quality are critical.

Designed for use in synchronized and non-synchronized gearboxes, gearbox/differential combinations, transfer cases, and hypoid differentials without limited slip systems, this fluid is ideal for motorsport applications including rally, raid, and track use. It performs exceptionally well under shock loads, heavy torque, low-speed crawling, and high-speed driving conditions.

What sets this Motul gear oil apart is its zero shear loss formulation, meaning the oil maintains its viscosity and protective film even under extreme mechanical stress. It remains in grade after rigorous shear testing (KRL 20-hour test), ensuring consistent lubrication and protection over time. This translates directly to longer component life, reduced wear, and reliable performance when you need it most.

The 90-grade viscosity at operating temperature provides a strong oil film to protect gears under load while also helping reduce transmission noise. At the same time, its fluid characteristics at lower temperatures allow for smoother cold shifts and reduced effort on the gear lever—something drivers will immediately notice in real-world conditions.

Motul’s advanced formulation also ensures compatibility with seals and yellow metals commonly found in gearbox construction, making it a safe and effective option across a wide range of applications.

If you're looking for a high-quality GL-4 / GL-5 gear oil that delivers consistent performance in racing environments or demanding street use, this Motul fluid is built to perform.
