Mobil Delvac 1™ Gear Oil 80W-140

Mobil Delvac 1™ Gear Oil 80W-140
Mobil Delvac 1 Gear Oil 80W-140 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 80W-140 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 80W-140 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. It is 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.
