Motul Gear 300 75W-90 Synthetic Gear Oil

Motul Gear 300 75W-90 Synthetic Gear Oil - 1L

Maximum Protection and 0 Percent Shear Loss for Racing Transmissions

Experience total drivetrain confidence with Motul Gear 300. Engineered for use in synchronized or non-synchronized gearboxes, transfer cases, and hypoid differentials without limited-slip systems, this lubricant utilizes Motul's signature Ester technology to reduce internal friction and wear. Its unique formula is specifically designed to stay within its viscosity grade even after the most punishing shear tests, ensuring that your transmission noise is reduced and your gear engagement remains crisp and light, even during cold starts in freezing climates.

What’s Included in the Box:

- (1) 1 Liter (1.05 Quart) Bottle: Ergonomic bottle with integrated pour spout for clean filling.

The Motul Advantage

- 100 Percent Synthetic Ester Base: Reinforced with Extreme Pressure (EP) additives for superior anti-wear protection and high-temperature stability.

- Zero Shear Loss: The unshearable oil film maintains its 90-grade viscosity even under extreme shocks and heavy loads, as per the SAE J306 standard.

- Improved Shift Quality: High lubricating power reduces the effort required on the gear lever, allowing for faster and smoother shifting in all temperature ranges.

- Drivetrain Efficiency: By decreasing friction, this fluid helps maximize power delivery to the wheels while reducing operating temperatures within the gearbox.

- Seal Compatibility: Formulated to be safe for all types of seals and "yellow" materials (like brass synchros) used in modern and classic transmission designs.

Precision Tip: This specific fluid is designed for manual transmissions and "open" differentials. If your vehicle is equipped with a plate-type Limited Slip Differential (LSD), you should use Motul Gear 300 LS instead, which contains the friction modifiers necessary to prevent LSD chatter. For most performance applications, we recommend checking your gear oil every 15,000 to 30,000 miles, or sooner if the vehicle is frequently used on the track.
