Mobilube™ HD Plus

An extra high-performance commercial gear oil

Mobilube HD Plus is an extra high-performance gear lubricant formulated from select base oils and an advanced additive system. It can be used for on-highway light- and heavy-duty trucks, buses, vans and cars. It provides excellent chemical and thermal stability at elevated bulk oil temperatures, performs well at low temperatures, and has demonstrated good protection from rust resulting from water contamination and wet conditions.


Features and 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

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

Applications
Recommended by ExxonMobil for use in:

  • Heavy-duty manual transmissions, axles and final drives requiring API GL-5 gear oil 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
  • Not recommended for applications requiring API GL-4 level performance
  • Not intended for transmissions for which engine oil or automatic transmission fluids are recommended
