Mobil Delvac Synthetic Gear Oil 80w-140, 105 pound keg is a synthetic drivetrain lubricant engineered to meet the most demanding extended drain and warranty requirements. This product is 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 Synthetic Gear Oil 80w-140, 105 pound keg incorporates the latest technology in synthetic basestocks and advanced additives providing significant advantages over mineral gear oils. This product meets 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. It also has the following benefits:

Exceptional thermal stability and resistance to high temperature oxidation:Extended gear and bearing life due to minimal depositsLonger seal lifeOutstanding protection against low speed/high torque wear and high speed scoring:Increased load-carrying capabilityReduced maintenance costs and longer equipment lifeExceptional shear stability:Retains viscosity and film strength under severe operating conditions to prevent wearExcellent rust, staining, and corrosion protection of copper and its alloys:Reduced wear and longer component lifeEnhanced friction reduction properties:Improved fuel economy and reduced operating costsOutstanding low temperature fluidity versus mineral oils:Reduced wear and ease of start-upGood resistance to foaming:Maintains film strength for reliable lubricationCompatible with typical automotive seals and gaskets:Minimum leakage and reduced contamination

Application

• 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
• Use as a companion with Mobil Delvac Synthetic Transmission Fluid 50 in transmissions for maximum drive train life, efficiency and fuel economy improvement
• 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
