Mobil HD-A 85W-90 

Mobilube™ HD-A 85W-90

Automotive Gear Lubricant

Mobilube HD-A 85W-90 is a heavy duty gear lubricant formulated from high performance base oils and an advanced additive system. This lubricant is engineered for commercial transmissions, axles, and final drives where extreme pressures and shock loading are expected and is recommended by ExxonMobil for applications performance where API GL-5 service is required.

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 minimise operating costs. Longer service intervals place additional demands on the gear lubricant requiring effective basestock and additive systems. Mobilube HD-A 85W-90 gear lubricant is engineered to meet these challenges. The key benefits include:

Features Advantages and Potential Benefits
Excellent thermal stability and resistance to high temperature oxidationExtended gear and bearing life due to minimal deposits
Longer seal life
Good protection against low speed/high torque wear and against high speed scoring especially in heavily loaded rear axlesIncreased load carrying capability
Reduced maintenance costs and longer equipment life
Effective rust and corrosion protectionReduced wear and longer component life
Multipurpose capabilityReduced number of gear lubricants required
Compatible with typical automotive seals and gasketsMinimum leakage and reduced contamination
Extended drain capabilityIncreased productivity and reduced operating costs

Recommended by ExxonMobil for use in:

  • Heavy duty automotive manual transmissions, axles, and final drives requiring API GL-5 level performance
  • On highway cars and light trucks; heavy duty commercial vehicles
  • Off highway industries including: construction, mining, quarrying, and agriculture
  • Other gearboxes, steering gears and variable gearboxes
  • Other heavy duty industrial and automotive applications involving hypoid gears operating under conditions where high speed/shock load, high speed/low torque, and/or low speed/high torque prevail
