Motul Motylgear 75W-90 Technosynthese GL-4 GL-5 Manual Gear Oil 1L

Motul Motylgear 75W-90 is a Technosynthese extreme-pressure transmission lubricant formulated for demanding manual transmission, gearbox, transfer-case, and differential applications requiring SAE 75W-90 and API GL-4 or GL-5 performance.

It is especially recommended for hard-to-shift or noisy gearboxes and is suitable for synchronized and non-synchronized manual transmissions, gearbox/differential units, transfer gearboxes, and hypoid differentials without limited-slip systems.

The reinforced synthetic base-stock formulation provides strong anti-wear protection, high-temperature resistance, stable viscosity, reduced friction, and easier cold shifting under demanding operating conditions.

This package includes one 1-liter bottle for compatible transmission and differential service.

WHY THIS GEAR OIL:

The Technosynthese extreme-pressure formulation provides reinforced protection against wear in heavily loaded transmission components.

It maintains SAE 90 high-temperature viscosity after severe shear testing, helping preserve a strong lubricant film under high temperatures and heavy mechanical loads.

Excellent lubricating performance helps reduce friction, gear wear, and transmission noise.

Strong low-temperature fluidity supports easier shifting when the gearbox is cold, reducing shift effort and improving driving comfort.

The formulation also provides anti-corrosion and anti-foam protection and is suitable for seals and yellow-metal materials used in compatible gearbox designs.

FITMENT AND COMPATIBILITY NOTE:

Use only where SAE 75W-90 and API GL-4, API GL-5, or MIL-L-2105D gear lubricant performance is permitted.

This lubricant is suitable for synchronized and non-synchronized manual transmissions, transfer gearboxes, gearbox/differential units, and compatible hypoid differentials.

It is intended for hypoid differentials without limited-slip systems. Do not use it as a substitute for a dedicated limited-slip differential lubricant when the vehicle requires specific LSD friction characteristics.

Always verify the vehicle or transmission manufacturer’s required viscosity grade, API classification, fluid capacity, and service procedure before use.

IMPORTANT NOTES:

Transmission oil-change intervals should follow the vehicle or transmission manufacturer’s requirements and be adjusted for severe service, high temperatures, competition use, towing, or heavy loads.

Do not assume that every GL-4 or GL-5 application is interchangeable. Confirm the exact fluid specification required for the transmission, differential, or transfer case.

For applications equipped with a limited-slip differential, use the specific LSD-compatible lubricant required by the manufacturer.
