Mobil Delvac 1 Gear Oil 80W-140

Mobil Delvac 1™ Gear Oil 80W-140

Mobil Delvac 1™ Gear Oil 80W-140 are synthetic drivetrain lubricants engineered to meet the most demanding extended drain and warranty requirements. These products are designed for use in heavy-duty drivetrains that require gear lubricants with relatively high viscosity and excellent load-carrying capability and where extreme pressures and shock loading are expected. Mobil Delvac 1 Gear Oil 80W-140 incorporate the latest technology in synthetic basestocks and advanced additives providing significant advantages over mineral gear oils.

The state-of-the-art technology in Mobil Delvac 1 Gear Oil 80W-140 delivers unsurpassed performance for low and high temperature application, protection against thermal degradation and oxidation, reduced wear and corrosion, improved shear stability, extended service capability, and excellent fuel economy. These products meet or exceeds the requirements of API service MT-1/GL-5 EP gear oil service classification and are recommended by ExxonMobil for use in applications requiring the MIL-PRF-2105E specification.

Today’s technology has vastly improved the performance capabilities of heavy-duty on and off-highway equipment load, torque, speed, and control through innovative drivetrain designs. These designs have changed and increased the requirements of lubricants to deliver this higher level of performance, increase productivity, and reduce operating costs. For heavy-duty final drives, friction control, wear protection, thermal stability, shear stability, rust and corrosion prevention, and seal protection are features that must be optimally balanced to provide extended gear and seal life, smooth operation, improved fuel economy and high load high torque capability over a wide range of applications. The key benefits of Mobil Delvac 1 Gear Oil 80W-140 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 high speed scoringIncreased load-carrying capability
Reduced maintenance costs and longer equipment life
Exceptional shear stabilityRetains viscosity and film strength under severe operating conditions to prevent wear
Excellent rust, staining, and corrosion protection of copper and its alloysReduced wear and longer component life
Enhanced friction reduction propertiesImproved fuel economy and reduced operating costs
Outstanding low temperature fluidity versus mineral oilsReduced wear and ease of start-up
Good resistance to foamingMaintains film strength for reliable lubrication
Compatible with typical automotive seals and gasketsMinimum leakage and reduced contamination

Recommended by ExxonMobil for use in:

  • Heavy-duty manual transmissions, axles and final drives requiring API GL-5 and MT-1 performance
  • On-highway light and heavy-duty trucks, busses and vans
  • Off-highway industries including: construction, mining, quarrying, and agriculture
  • Other heavy-duty industrial gear drives including hypoid and worm gears operating under conditions where high speed/shock load, high speed/low torque, and/or low speed/high torque conditions prevail
  • Differentials, final drives, transfer cases and other gear applications where lubricants meeting MIL-PRF-2105E, API Service GL-5 , EP gear lubricants are recommended
  • Equipment such as winch reduction gears and crawler vehicle propulsion gear drives that are exposed to severe low temperatures
  • Applications where extended service intervals and warranties are required
  • Not recommended for applications requiring API GL-4 Level performance
  • Not intended for automatic, manual or semiautomatic transmissions for which engine oil or automatic transmission fluids are recommended
