Delvac 1 Gear Oil 75W-90

The Mobil Delvac 1 Gear Oil 75W-90 is a fully synthetic drivetrain lubricant engineered to meet demanding extended drain and warranty requirements for heavy-duty vehicles. Its advanced formula, incorporating synthetic base stocks and sophisticated additives, provides superior protection against thermal degradation, oxidation, wear, and corrosion, while improving shear stability and extending service capability compared to conventional gear oils. This lubricant offers exceptional thermal stability and resistance to high-temperature oxidation, contributing to longer gear and bearing life by minimizing deposits and ensuring extended seal life. It provides outstanding protection against low-speed/high-torque wear and high-speed scoring, increasing load-carrying capability to help reduce maintenance costs and prolong equipment life. The enhanced friction reduction properties may contribute to potential fuel economy improvements and reduced operating costs. Mobil Delvac 1 Gear Oil 75W-90 is suitable for use in on-highway light and heavy-duty trucks, buses, and vans, as well as off-highway applications in construction, mining, quarrying, and agriculture. It is intended for initial fill, topping-off, or refilling differentials, final drives, and transfer cases, and is recommended for equipment like winch reduction gears and crawler vehicle propulsion gear drives exposed to severe low temperatures, as well as applications requiring extended service intervals and warranties. It meets API GL-5 and MT-1 performance requirements and holds numerous OEM approvals, including Mack GO-J Plus, MB-Approval 235.9, and ZF TE-ML specifications. Important: This oil is not recommended for applications requiring API GL-4 level performance. It is also not intended for automatic, manual, or semi-automatic transmissions that specify engine oil or automatic transmission fluids. Always refer to your owner's handbook for specific OEM application requirements.
