Motul Gear 300 75W90 - 100% Synthetic Gear Oil 105777 1L 9 Pack

PRODUCT OVERVIEW: Motul Gear 300 75W-90 is a high performance synthetic technology gear oil designed for manual transmissions, gearboxes, transfer cases, and hypoid differentials without limited slip systems operating under shock loads, heavy loads, and high performance driving conditions. It is suitable for synchronized or non-synchronized gearboxes and is built for applications that demand strong protection under both low-speed/high-load and high-speed/moderate-load conditions. This formulation is engineered for outstanding oil film resistance, high-temperature stability, reduced friction and wear, and easier shifting when cold. The 75W-90 viscosity grade provides strong hot-temperature protection while maintaining fluidity at low temperature for more comfortable gear engagement. WHY THIS OIL: This oil is built around the technical requirements performance and enthusiast buyers usually search for first, especially API GL-4, API GL-5, and MIL-L 2105 D compatibility. It is designed for racing vehicle gearboxes and transmissions as well as other high-load mechanical transmission applications. It uses synthetic technology with ester extreme pressure lubrication for strong anti-wear protection, better high-temperature resistance, and longer service life. The formulation is also described as having 0% shear loss, helping maintain an unshearable oil film in extreme conditions. BEST FOR: This oil is best for manual gearboxes, gearbox/differential units, transfer gearboxes, and hypoid differentials without limited slip that require 75W-90 gear oil meeting GL-4 or GL-5 performance levels. It is especially relevant for performance street driving, racing applications, rally-style use, and other high-load transmission environments where strong film strength, shift feel, and wear control matter. It is also suitable for transmissions containing yellow metals and for systems using a wide variety of seal materials. KEY SPECIFICATIONS: VISCOSITY GRADE: SAE 75W-90 STANDARDS: API GL-4, API GL-5, MIL-L 2105 D TYPICAL PROPERTIES: Density at 20°C 0.897, KV at 40°C 86.5 mm2/s, KV at 100°C 14.2 mm2/s, Viscosity Index 170, Pour Point -54°C, Flash Point 204°C OEM APPROVALS AND PERFORMANCES: API GL-4, API GL-5, MIL-L 2105 D FITMENT AND COMPATIBILITY NOTE: Always confirm the required gear oil specification and viscosity grade in the owner’s manual before purchase. This product is intended for mechanical transmissions and hypoid differentials without limited slip systems where 75W-90, GL-4, or GL-5 performance is specified. Oil change interval should follow the vehicle manufacturer recommendation and be adjusted based on actual use. IMPORTANT NOTES: This product is intended for non-limited-slip differential applications. For differentials that specifically require a limited slip friction modifier, a dedicated limited-slip gear oil should be used instead. This oil is designed to provide easy shifting when cold, reduced shift effort, anti-corrosion protection, and anti-foam performance.
