Motul Gear Competition 75W-140 Synthetic Gear Oil

Motul Gear Competition 75W-140 Synthetic Gear Oil - 1L

Maximum Protection for High-Load Racing Differentials

Protect your drivetrain with the ultra-high-viscosity performance of Motul Gear Competition. This lubricant is specifically engineered for all limited-slip differentials (LSD), gearboxes with integrated LSD, and mechanical transmissions operating under heavy shocks and high temperatures. Whether you are competing in endurance racing, drifting, or high-power street applications, the 140-weight high-temperature viscosity ensures superior gear teeth protection and quiet operation while maintaining the necessary friction characteristics for smooth limited-slip engagement.

What Included in the Box:

- (1) 1 Liter (1.05 Quart) Bottle: Features a specialized pour spout for easier access to tight fill ports.

The Motul Advantage

- 100 Percent Synthetic Ester Technology: Provides an exceptionally high oil film resistance at high temperatures, significantly reducing friction and mechanical wear.

- Extreme Pressure (EP) Protection: Formulated to withstand the intense pressures of hypoid gears and heavy shock loads common in competitive motorsport.

- Integrated LSD Additives: Contains the specific friction modifiers required for plate-type limited-slip differentials, eliminating chatter and ensuring consistent locking performance.

- 0 Percent Shear Loss: Maintains its 140-grade viscosity even after the most severe mechanical stress tests, ensuring long-term protection for expensive drivetrain components.

- High Temperature Stability: Designed to operate at elevated temperatures for extended periods without oxidation or thermal breakdown.

Precision Tip: The 75W-140 weight is a "heavy-duty" fluid typically reserved for track-only vehicles or those operating in extremely hot climates. While it offers superior protection for high-load differentials, the higher viscosity may result in slightly higher internal drag and slower gear engagement in cold weather compared to a 75W-90. Always confirm your component manufacturer's recommended viscosity before switching from a standard weight fluid.
