Standards & approvals

• Mack GO-J

  Official approval

  Mack GO-J — axle/hypoid gear oil

  Mack specification for hypoid gear oils in truck axles and heavily loaded manual transmissions.

• SAE J2360

  Official approval

  SAE J2360 — registered EP axle oil

  Standard that took over the MIL-PRF-2105E military specification; unlike API GL-5 it requires product registration and axle rig testing.

• API GL-5

  Gear oil, API GL-5 service level

  API's service designation for axle and manual transmission oils.

• API MT-1

  Gear oil, API MT-1 service level

  API's service designation for axle and manual transmission oils.

Manufacturer's description

Mobilube HD Plus SAE 85W-140 is an extra-high-performance commercial gear lubricant formulated from select base oils and an advanced additive system. It is engineered for heavy-duty commercial transmissions, axles and final drives where extreme pressures and shock loading are expected, offering excellent chemical and thermal stability at elevated bulk oil temperatures, good low-temperature performance and demonstrated rust protection under water contamination or wet storage conditions. It is recommended by ExxonMobil for heavy-duty manual transmissions, axles and final drives requiring API GL-5 and MT-1 performance, across on-highway trucks, buses, vans and cars and off-highway construction, mining, quarrying and agricultural equipment, including hypoid and other gears under high-speed/shock-load, high-speed/low-torque or low-speed/high-torque conditions. It is not recommended for applications requiring API GL-4 performance or for transmissions requiring engine oil or automatic transmission fluid. Key benefits include excellent rust, staining and corrosion protection, effective low-temperature lubrication, wide multipurpose capability, good foam resistance and compatibility with typical automotive seals and gaskets. Mobilube HD Plus SAE 85W-140 meets or exceeds API GL-5 and MT-1, and carries approvals including Mack GO-J, SAE J2360 and Volvo 97321, with quality level to MIL-PRF-2105E and performance to Meritor O-94 and Scania STO 1:0.

Applications

• Heavy-duty manual transmissions, axles and final drives requiring API GL-5 and MT-1 level performance.
• On-highway light- and heavy-duty trucks, buses, vans and cars.
• Off-highway industries including construction, mining, quarrying and agriculture.
• Other heavy-duty industrial and automotive applications involving hypoid and other gears operating under high-speed/shock-load, high-speed/low-torque and/or low-speed/high-torque conditions.
• Initial fill, top-off and refill of enclosed commercial gearing in manual or semi-automatic transmissions where gear lubricants are recommended, including drive axles and final drives.
• Not recommended for applications requiring API GL-4 level performance, or for transmissions where engine oil or automatic-transmission fluid is recommended.

Performance & benefits

• Excellent thermal stability and resistance to high-temperature oxidation: extends gear and bearing life through minimal deposits, and extends seal life.
• Good protection against low-speed/high-torque wear and high-speed scoring: increases load-carrying capability and reduces operating costs.
• Excellent rust, staining and corrosion protection: reduced wear and longer component life.
• Effective low-temperature lubrication: reduced wear and easier start-up.
• Wide multipurpose capability: fewer gear lubricants needed, simplifying inventory and minimising misapplication.
• Good resistance to foaming: maintains film strength for effective lubrication.
• Compatible with typical automotive seals and gaskets: minimal leakage and reduced contamination.
