MANNOL 8107 Gear Oil 80W-90 for Manual Transmissions

Vehicle and Application Recommendations

Product Overview

MANNOL 8107 Universal Gear Oil SAE 80W-90 API GL-4 is a universal all-season, mineral-based gear oil developed for manual transmission applications.

It is designed for synchronized and non-synchronized manual transmissions, as well as drive axles and other manual transmission components operating under normal and heavy loads.

The product is intended for applications where the required level of service characteristics is API GL-4.

MANNOL 8107 Gear Oil 80W-90 Specifications

Mineral-Based Formulation for Manual Transmissions

MANNOL 8107 is a mineral-based gear oil formulated for manual transmission and drivetrain applications.

Its SAE 80W-90 viscosity grade is intended for applications where this viscosity is specified by the vehicle or equipment manufacturer.

The formulation is designed for manual transmission components that operate under both sustainable and heavy loads.

The correct lubricant should always be selected according to the transmission manufacturer's specified viscosity and service requirements.

SAE 80W-90 Viscosity Grade

The SAE 80W-90 classification describes the viscosity grade of the gear oil.

The "80W" part relates to the oil's low-temperature viscosity classification, while "90" identifies its higher-temperature viscosity grade.

However, SAE viscosity alone does not determine whether the product is suitable for a particular transmission.

Before using MANNOL 8107, check that the vehicle or equipment manufacturer specifies SAE 80W-90 together with the required service classification.

API GL-4 Gear Oil Performance

API GL-4 is the specified service level for MANNOL 8107.

The product is intended for manual transmission and drivetrain applications where the manufacturer requires a GL-4 lubricant.

This is particularly important when selecting gear oil because different transmissions can require different lubricant performance levels.

For this reason, the correct selection should be based on the manufacturer's specification rather than choosing a gear oil only from the vehicle type or viscosity grade.

Synchronized and Non-Synchronized Manual Transmissions

MANNOL 8107 is developed for both synchronized and non-synchronized manual transmissions, provided the manufacturer's required lubricant specification matches the product.

Manual transmission designs differ in their lubrication requirements. Synchronizer systems, gears and other internal components may have specific lubricant requirements.

Therefore, the transmission manufacturer's recommendation should be checked before replacing the existing gear oil.

Drive Axles and Other Transmission Components

The supplied product information also identifies drive axles and other components of manual transmissions as applications.

For these applications, the required viscosity and service specification should be verified against the equipment or vehicle manufacturer's instructions.

This helps ensure that the lubricant selected corresponds with the intended component and operating conditions.

Designed for Sustainable and Heavy Loads

Manual transmission and drivetrain components can operate under different load conditions depending on the vehicle and application.

MANNOL 8107 is developed for components operating under sustainable and heavy loads.

The product is therefore positioned for applications ranging from passenger vehicles to heavy-load highway, off-road and special-purpose vehicles where the required service level is API GL-4.

Actual operating performance will depend on the vehicle, transmission design, load, temperature, maintenance condition and the manufacturer's specified lubricant requirements.

Highway, Off-Road and Special Vehicle Applications

MANNOL 8107 is recommended for manual transmission applications across several vehicle categories.

European, American and Asian Vehicle Manufacturers

MANNOL 8107 is described as suitable for applications involving vehicles produced by European, American and Asian manufacturers.

This does not mean that every vehicle from these regions is automatically compatible.

The individual transmission or drivetrain specification remains the deciding factor. The manufacturer's manual should be checked for the required:

MIL L 2105 Specification

MANNOL 8107 is listed with the MIL L 2105 specification.

This specification is included alongside SAE 80W-90 and API GL-4 in the supplied product information.

When selecting a gear oil, the complete set of required specifications should be compared with the product documentation rather than relying on one specification alone.

Why the Correct Gear Oil Specification Matters

Choosing gear oil is not simply about selecting an 80W-90 product.

The transmission manufacturer may specify:

For MANNOL 8107, the supplied specifications are SAE 80W-90, API GL-4 and MIL L 2105.

The product should therefore be used when these requirements are appropriate for the intended application.

How to Choose MANNOL 8107 Gear Oil 80W-90

Before purchasing or replacing gear oil, check the following:

1. Check the owner's manual
   Find the lubricant specification recommended for the transmission or axle.
2. Confirm the viscosity
   Check whether SAE 80W-90 is specified.
3. Check the API requirement
   Confirm that API GL-4 is the required service level.
4. Identify the component
   Confirm whether the oil is intended for the manual transmission, drive axle or other listed component.
5. Check the operating application
   Consider whether the vehicle is used for highway, off-road, agricultural, construction, mining or special-purpose operation.
6. Follow the manufacturer's instructions
   The final selection should always comply with the vehicle or equipment manufacturer's recommendations.
