The Mobilube HD Plus Gear Oil 85W-140 is an extra-high-performance commercial gear oil engineered for demanding heavy-duty applications. It utilizes select base oils and an advanced additive system to provide superior protection in transmissions, axles, and final drives that experience extreme pressures and shock loading. This formulation offers excellent thermal stability and resistance to high-temperature oxidation, which helps extend gear and bearing life by minimizing deposits and ensuring longer seal life. It provides robust protection against wear, including low-speed/high-torque wear and high-speed scoring, leading to increased load-carrying capability and reduced operating costs. Furthermore, it offers excellent rust, staining, and corrosion protection, contributing to reduced wear and longer component life. The oil also ensures effective low-temperature lubrication for reduced wear and easier start-up. Mobilube HD Plus 85W-140 is recommended for heavy-duty manual transmissions, axles, and final drives that require API GL-5 and MT-1 level performance. It is suitable for on-highway light and heavy-duty trucks, buses, vans, cars, and off-highway industries like construction, mining, quarrying, and agriculture. It is also recommended for initial fill, top-off, and refill of enclosed commercial gearing in manual or semi-automatic transmissions. Important: This lubricant is not recommended for applications requiring API GL-4 level performance. It is also not intended for transmissions that recommend engine oil or automatic transmission fluids. Always refer to the owner's handbook for OEM application requirements.
