Product Description

Mobilube GX-A 80W is an automotive 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 protection against wear and scoring is required.  It is recommended by ExxonMobil for use in Mercedes Benz applications where MB-Approval 235.1 is required and in applications where API GL-4 service is required.


Features and Benefits

Today’s drivetrain applications place higher performance demands on 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 requiring effective basestock and additive systems. Mobilube GX-A 80W is engineered to meet these challenges. The key benefits include:

FeaturesAdvantages and Potential Benefits
Good thermal stability and resistance to high temperature oxidationLong gear and bearing life due to minimal deposits
Long seal life
Excellent rust and corrosion protectionLong component life
Good low temperature lubricationReduced wear at start-up and ease of start-up
Compatible with typical automotive seals and gasketsMinimum leakage and reduced contamination



      Recommended by ExxonMobil for use in:

  • Manual transmissions and drive axles requiring API GL-4 level performance
  • Passenger cars, onhighway light and heavy-duty trucks and commercial vehicles
  • Off-highway industries including: construction, quarrying, and agriculture
  • Other industrial, commercial, and automotive applications including hypoid gears operating under moderate to severe operating conditions
