对于有限的滑移差分应用，它可能是必要的，使用一个特殊的工厂提供的齿轮润滑剂，需要最终的颤振控制
Mobilube HD-N 80W-140
Extra High Performance Commercial Gear Lubricant
Product Description
Mobilube HD-N 80W-140 is an extra high performance commercial gear lubricant engineered from select base oils and an advanced additive system. This lubricant is formulated for performance in heavy-duty transmissions, axles, and final drives where extreme pressures and shock loading are expected. It provides excellent chemical and thermal stability at elevated bulk oil temperatures, good performance at low temperatures and has demonstrated good rust protection resulting from water contamination and/or storage in wet conditions.
Features and Benefits
Today's heavy equipment applications place higher performance demands on drivetrain lubricants. Higher speeds, higher torque, and heavier loads require improved formulations to maximise equipment life and minimise operating costs. Longer service intervals place additional demands on the gear lubricant. Mobilube HD-N 80W-140 gear lubricant is engineered to meet these challenges. Key benefits include:
|

Applications
Recommended by ExxonMobil for use in:
-
Heavy duty manual transmissions, axles, and final drives requiring API GL-5 level performance including Scania
-
On-highway light and heavy duty trucks, busses, vans, and cars
-
Off-highway industries including: construction, quarrying, and agriculture
-
Other heavy-duty industrial and automotive applications involving hypoid and other gears operating under conditions where high speed/shock load, high speed/low torque, and/or low speed/high torque conditions prevail
-
Initial fill, top-up, and refill of enclosed commercial-type gearing in manual or semiautomatic transmissions where gear lubricants are recommended including drive axles and final drives of trucks, off-highway equipment, and cars
-
Not recommended for applications requiring API GL-4 level performance
-
Not intended for transmissions for which engine oil or automatic transmission fluids are recommended
-
For limited-slip differential applications, it may be necessary to use a special factory-provided gear lubricant for those requiring ultimate chatter control
