Mobilube™ HD Plus Gear Oil 80W-90

Extra-high-performance commercial gear oils

Bottle of Mobilube™ HD Plus Gear Iuk

Mobilube™ HD Plus Gear Oil 80W-90 and 85W-140 are extra-high-performance commercial gear oils formulated from select base oils and an advanced additive system. These oils are engineered for performance in heavy-duty commercial transmissions, axles and final drives where extreme pressures and shock loading are expected.

Mobilube HD Plus Gear Oil provides excellent chemical and thermal stability at elevated bulk oil temperatures, good performance at low temperatures, and have demonstrated good rust protection resulting from water contamination and wet conditions. Mobilube HD Plus Gear Oil shares common formulations with Esso™ Gear Oil GX 80W-90 and 85W-140.

Mobilube HD Plus Gear Oil is recommended by ExxonMobil for use in:

  • 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 conditions where high-speed/shock load, high-speed/low-torque, and/or low-speed/high-torque conditions prevail
  • Initial fill, top-off and refill of enclosed commercial gearing in manual or semiautomatic transmissions where gear lubricants are recommended, including drive axles and final drives

Important: These lubricants are not recommended for applications requiring API GL-4 level performance. They are not intended for transmissions for which engine oil or automatic transmission fluids are recommended.

Please refer to the owner's handbook for the OEM application requirements for your vehicle or equipment.

Features and Benefits

Today's heavy equipment applications place higher performance demands on drive train lubricants. Higher speeds, higher torque, and heavier loads require improved formulations to maximise equipment life and optimise operating costs. Longer service intervals place additional demands on the gear lubricant. Mobilube HD Plus gear lubricants are engineered to meet these challenges. The key benefits include:

Features Advantages and Potential Benefits
Excellent thermal stability and resistance to high temperature oxidation Extended gear and bearing life due to minimal deposits and longer seal life
Good protection against low speed/high torque wear and against high speed scoring Increased load carrying capability and reduced operating costs
Excellent rust, staining, and corrosion protection Reduced wear and longer component life
Effective low temperature lubrication Reduced wear and ease of start-up
Wide multipurpose capability Reduced number of gear lubricants to simplify inventory and minimize misapplication
Good resistance to foaming Maintains film strength for effective lubrication
Compatible with typical automotive seals and gaskets Minimum leakage and reduced contamination
