Motul Transmission GEAR 300 75W90 - Synthetic Ester - 20L Orange Jerry Can

If you're running a performance vehicle, track build, or race application, your gearbox fluid needs to do more than just lubricate—it needs to hold up under pressure, heat, and constant stress. Motul SAE 90 synthetic gear oil is designed specifically for high-performance manual transmissions and racing gearboxes where consistency and protection are critical.

Built for synchronized and non-synchronized transmissions, this fluid is ideal for gearbox/differential setups, transfer cases, and hypoid differentials that do not require limited slip additives. It performs exceptionally well in motorsport environments such as rally, raid, and track driving, where driveline components are constantly exposed to shock loads, heavy torque, and varying speeds.

What makes this fluid stand out is its unshearable oil film, meaning it maintains its viscosity and protective properties even under extreme mechanical stress. Unlike conventional gear oils that break down over time, this formula stays in grade after extended shear testing, delivering consistent lubrication and long-term protection.

At operating temperature, the SAE 90 viscosity provides a durable oil film that protects gears under load and helps reduce drivetrain noise. At the same time, its cold-flow characteristics allow for smoother engagement during startup and easier gear changes in lower temperatures—giving you better drivability across all conditions.

This Motul gear oil is also engineered to be compatible with modern gearbox materials, including yellow metals, and provides anti-corrosion and anti-foam protection to maintain performance over time.

Whether you're maintaining a high-performance street car or preparing a dedicated race setup, this fluid is designed to deliver reliability, protection, and consistent performance where it matters most.
