Mobilube XFD Series

Mobil commercial-vehicle-lube , Belarus

Extra High Performance Drivetrain Lubricants

Product Description

Mobilube XFD 50 and 60 are extra high performance drivetrain lubricants engineered specifically to provide optimum component life when used as recommended in Caterpillar final drives and axles.  They are formulated from advanced base oils and the latest additive technology to protect bearings and gears from premature failure due to fatigue.  These lubricants deliver excellent performance in heavy-duty commercial axles and final drives where extreme pressures and shock loading are expected.  They provide exceptional chemical and thermal stability at elevated bulk oil temperatures generated under heavy loads and/or high ambient temperatures.


Mobilube XFD Series have been extensively field tested in Caterpillar off-highway heavy trucks and bulldozers over a wide range of ambient temperatures and operating in severe conditions with a recommended drain interval up to 4,000 hours for off-highway haulers.


Features and Benefits

Demands for higher productivity, more severe operating conditions, and larger capacity equipment put severe stress on axles and final drive components. In severe applications, TO-4 lubricants may be limited in terms of wear protection in heavily loaded final drives due to their need to also serve the frictional requirements of clutches in heavy-duty transmissions. For optimum durability and performance, Mobilube XFD gear lubricants can be relied on to maintain productivity and minimize maintenance costs between scheduled service intervals in extreme applications. The key benefits include:



Advantages and Potential Benefits

Improved extreme pressure (EP) performance versus TO-4 fluids

Increased load and shock carrying ability with reduced premature failures and operating costs

High oxidation and thermal stability

Longer oil life, reduced deposits, and extended component life

Excellent protection against copper corrosion and rust

Extended component life and lower maintenance costs

Wide temperature capability

Simplifies inventory and reduces need for seasonal change-outs

Good compatibility with seals and conventional drive train lubricants

Reduces leakage and contamination from external sources

Eliminates or reduces foaming

Maintains film strength for reliable wear protection



Recommended by ExxonMobil for use in:

     •  Heavy-duty axles and final drives used in trucks and bulldozers built by Caterpillar
