Mobil Delvac 1 Final Drive and Axle Oil

Mobil Delvac™ 1 Final Drive and Axle Oil is an extra high performance drivetrain lubricant that meets the requirements of the Caterpillar FD-1 standard. It is specifically engineered to provide optimum component life when used as recommended in off-highway truck and bulldozer final drives, axles, bevel gears, and differentials, especially those operating under high loads and extreme temperatures. It is formulated from advanced synthetic base oils and the latest additive technology to enable extended oil drain intervals and prolong the life of bearings and gears. The synthetic base oil composition enables excellent performance in some of the harshest operating conditions and over a wide temperature range, in high temperatures as well as temperatures down to -35c.


Features and Benefits

Today's technology has vastly improved the performance capabilities of heavy-duty off-highway equipment innovative drivetrain designs. Additionally, increasing demands for higher productivity and more severe operating conditions put severe stress on axles and final drive components. For optimum durability and performance, Mobil Delvac 1 Final Drive and Axle Oil can be relied on to maintain productivity and minimize maintenance costs.


Features Advantages and Potential Benefits
Excellent load carrying, anti-wear, and EP performance Helps extend component life and reduce cost of operation
Optimized thermal and oxidation protection Long oil life, extended drain and service intervals, and extended component life
Exceptional shear stability Helps minimize wear during severe operation
Outstanding low-temperature fluidity Helps reduce wear during cold temperatures
Extended drain and service interval capability Helps provide lower operating costs and higher productivity



Mobil Delvac 1 Final Drive and Axle Oil is recommended for use in off-highway truck and bulldozer front wheels, differentials and final drives requiring CAT FD-1 lubricants. Note that Mobil Delvac 1 Final Drive and Axle Oil should not be used in compartments that contain frictional materials unless an oil meeting the FD-1 specification has been specified.
