Mobil Delvac 1 Gear Oil 75W-90 is a fully synthetic drivetrain lubricant engineered to meet very demanding extended drain and warranty requirements. This gear oil is designed for use in heavy-duty drivetrains that require gear lubricants with excellent load-carrying capability and where extreme pressures and shock loading are expected.

Mobil Delvac 1 Gear Oil 75W-90 incorporates synthetic base stocks and advanced additives, providing significant advantages over conventional gear oils. The state-of-the-art technology in Mobil Delvac 1 Gear Oil 75W-90 delivers excellent performance, helps to protect against thermal degradation and oxidation, and contributes to reduced wear and corrosion, improved shear stability and extended service capability.

This oil can be used for on-highway light- and heavy-duty trucks, buses and vans. Other applications include off-highway industries, such as construction, mining, quarrying and agriculture.

Important: This oil is 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

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 contribute to extended gear and seal life, smooth operation, improved fuel economy potential and high load high torque capability over a wide range of applications.

The key benefits of Mobil Delvac 1 Gear Oil 75W-90 include:
