Motul Motylgear Technosynthese Gear Oil – 75W-90 | API GL-4/GL-5 | MIL-L-2105D | 5 Litre

Protect your manual transmission, differential, or transfer case with Motul Motylgear — a Technosynthese® (semi-synthetic) extreme pressure gear oil rated for API GL-4, GL-5, and MIL-L-2105D specifications. Engineered for synchronized and non-synchronized manual gearboxes, gearbox/differential combinations, and transfer cases operating without a limited slip system, Motylgear delivers robust EP protection, anti-wear performance, and smooth gear shifting across a wide temperature range.

Note: Not formulated for limited slip differentials (LSD). For LSD applications, use Motul 90 PA.

Key Features

• API GL-4 / GL-5 / MIL-L-2105D Rated: Dual GL-4/GL-5 rating provides broad compatibility with manual gearboxes and differentials specifying either standard
• Technosynthese® Semi-Synthetic Formula: Synthetic base stocks deliver improved thermal stability, oxidation resistance, and EP protection compared to conventional mineral gear oils — extending fluid and component life
• Extreme Pressure (EP) Protection: Reinforced EP additives protect gear surfaces under shock loads, heavy loads, and high-speed operation
• Smooth Cold Shifting: High fluidity at low temperatures reduces gear lever effort and improves shift quality when the drivetrain is cold
• Reduced Gearbox Drag: 75W-90 viscosity minimizes drag at operating temperature while maintaining a robust protective film on gear surfaces
• Seal & Yellow Metal Compatible: Suitable for all seal types and yellow metal components used in gearbox design
• Anti-Corrosion & Anti-Foam: Additive package includes anti-corrosion and anti-foam properties for long-term drivetrain protection
