Mobil Delvac Synthetic Gear Oil

Mobil Delvac™ Synthetic Gear Oil

Advanced performance synthetic drivetrain lubricant

Mobil Delvac Synthetic Gear Oil is a synthetic drivetrain lubricant engineered to meet some of the most demanding extended drain and warranty requirements. These gear oils 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 Synthetic Gear Oil incorporates the latest technology in synthetic base stocks and advanced additives, providing significant advantages over mineral gear oils.

These oils can be used for on-highway light and heavy-duty trucks, buses and vans. Other applications include off-highway industries including: construction, mining, quarrying, and agriculture. See our product data sheet for more details.

Important: These oils are not recommended for applications requiring API GL-4 level performance. They are not intended for automatic, manual or semiautomatic transmissions for which engine oil or automatic transmission fluids are recommended.

Please refer to the owner’s handbook for the OEM application requirements for your vehicle or equipment.

Features and benefits

  • Exceptional thermal stability and resistance to high temperature oxidation helps to extend gear, bearing and seal life due to minimal deposits
  • Outstanding protection against low speed/high torque wear and against high speed scoring provides longer equipment life and reduced maintenance costs
  • Exceptional shear stability helps to retain viscosity and film strength under severe operating conditions to help prevent wear
  • Excellent rust, staining and corrosion protection of copper and its alloys helps to reduce wear and provide long component life
  • Enhanced frictional properties can help improve fuel economy potential by up to 1 percent and help reduce operating costs
  • Outstanding low temperature fluidity versus mineral oils helps to reduce wear at start up and make start up easier in cold conditions
