Technosynthese Gear Oil for Manual Transmissions and Differentials
Motul Motylgear 75W-90 is a Technosynthese gear lubricant for manual transmissions, gearboxes, transfer gearboxes, and differentials that require API GL-4 or API GL-5 performance. The 4 x 5 L package is identified by article 109057 and is designed for demanding mechanical gear applications.
Key Features
- 75W-90 viscosity for manual transmission and drivetrain lubricant applications.
- API GL-4 and API GL-5 performance classifications.
- MIL-L-2105D performance specification.
- Technosynthese formulation with synthetic base stocks.
- Extreme-pressure, anti-wear, anti-corrosion, and anti-foam protection.
- Compatible with seals and yellow metals when approved for the application.
- Suitable for synchronized and non-synchronized mechanical gearboxes.
Fitment
| Application | Compatibility | Requirements |
|---|---|---|
| Universal application | Manual transmissions, gearboxes, transfer gearboxes, and differentials | Use only where the vehicle or equipment manufacturer specifies a 75W-90 lubricant meeting the required API classification. Hypoid differentials must not require a limited-slip lubricant. |

Can it be used in an automatic transmission?
It is intended for manual transmissions and mechanical gearboxes. Do not use it in an automatic transmission unless the manufacturer specifically approves this lubricant.
Can it be used in a limited slip differential?
It is suitable for hypoid differentials without limited slip. Confirm the differential lubricant requirement before installation.
What viscosity is this lubricant?
The viscosity grade is SAE 75W-90.
What performance standards does it meet?
It meets API GL-4 and API GL-5 classifications and the MIL-L-2105D performance specification.
Is this a synthetic lubricant?
It uses Motul Technosynthese technology with synthetic base stocks.
What size package is included?
The package contains four 5 L containers for a total of 20 L.
When should the lubricant be changed?
Follow the vehicle or equipment manufacturer’s service interval and lubricant replacement instructions.
Does the fluid work with synchronized gearboxes?
It is suitable for synchronized and non-synchronized mechanical gearboxes when the specified viscosity and performance requirements match.
Installation Instructions
- Confirm that the gearbox, transfer gearbox, or differential manufacturer specifies SAE 75W-90 with the required API classification.
- Position the vehicle or equipment safely and identify the correct fill and drain points.
- Drain the used lubricant according to the service instructions and dispose of it through an approved recycling or waste facility.
- Inspect the drain plug, sealing surface, and fluid level requirements before refilling.
- Fill with the required amount of lubricant and avoid overfilling.
- Check for leaks, confirm the level after the lubricant settles, and follow the manufacturer’s final inspection procedure.
