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 maximize equipment life and minimize operating costs. Longer service intervals place additional demands on the gear lubricant requiring effective basestock and additive systems. Mobilube HD 80W-140 is engineered to meet these challenges. The key benefits include:

FeaturesAdvantages and Potential Benefits
Exceptional thermal stability and resistance to high temperature oxidationExtended gear and bearing life due to minimal deposits
Longer seal life
Outstanding protection against low speed/high torque wear and against high speed scoringIncreased load-carrying capability
Reduced maintenance costs and longer equipment life
Excellent rust and corrosion protectionReduced wear
Longer component life
Effective low temperature lubricationReduced wear and ease of start-up
Wide application capabilityReduced number of gear lubricants required
Compatible with typical commercial seals and gasketsMinimum leakage and reduced contamination



      Recommended by ExxonMobil for use in:

  • Heavy-duty axles and final drives requiring API GL-5 level performance
  • On-highway heavy-duty trucks and commercial vehicles
  • Off-highway industries including: construction, mining, quarrying, and agriculture
  • 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
