Mobil Delvac 1™ Gear Oil 80W-140
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.
