4. After-Market Oil Additives
Caterpillar does not recommend the use of aftermarket additives in oil. It is not necessary to use aftermarket additives in order to achieve the machines maximum
service life or rated performance. Fully formulated, finished oils consist of base oils and of commercial additive packages. These additive packages are blended into the base
oils at precise percentages in order to provide finished oils with performance characteristics that meet industry standards.
There are no industry standard tests that evaluate the performance of aftermarket additives in oil. There are also no industry standard tests that evaluate the compatibility
of these aftermarket additives in a finished oil. Aftermarket additives may not be compatible with the finished oils additive package, which could lower the performance
of the finished oil. The aftermarket additive could fail to mix with the finished oil. This could produce sludge. Caterpillar discourages the use of aftermarket additives in
To achieve the best performance from a Caterpillar engine, obey the following guidelines
1. Select the proper Caterpillar oil or a commercial oil that meets the specifications of the compartment.
2. To find the correct viscosity grade for your machine, see the table in the Operation and Maintenance Manual, Lubricant Viscosities information.
3. At the specified interval, service the engine or service the compartment. Use new oil and install a new oil filter.
4. Perform maintenance at the intervals that are specified in Operation and Maintenance Manual, Maintenance Interval Schedule.
5. Lubricating Grease
Caterpillar provides a number of greases in order to cover a variety of applications and extreme temperature conditions. See your Caterpillar dealer or see Special
Publication, PECP4025, One Safe Source for the part numbers.
Note: Some greases may not be used with other greases. When you use commercial grease, make sure that the grease is compatible with the grease that is currently used
in your system. If you have any questions concerning the compatibility of your grease, consult your supplier.
6. Multipurpose Greases
Multipurpose Lithium Complex Grease MPGL
Multipurpose Lithium Complex Grease is a National Lubricating Grease Institute NLGI No. 2 general purpose lithium complex grease for medium duty applications.
This product has good characteristics at high temperatures such as a dropping point
over 260°C 500°F. MPGL contains unleaded extreme pressure additives and antiwear inhibitors that provide extra protection in the following applications:
• Construction • Agricultural
7. Final Drive Oil and Swing Drive Oil
Applications • Power Shift Transmissions, Direct Drive Transmission, and Winches
• Final Drives: Track Type Tractors, Pipelayers, Skidders, Loaders, and Track Type Excavators
• Differentials and Final Drives: Wheel Tractors, Loaders, Skidders, Compactors, Motor Graders, Off-Highway Tractors, and Trucks
Caterpillar TransmissionDrive Train Oil
Caterpillar TransmissionDrive Train Oil is balanced in order to give maximum frictional material life in power shift transmissions. Caterpillar Transmission Drive Train Oil also
eliminates brake chatter in wet brake applications in Caterpillar machines. This oil has passed the requirements for the TO-4 oil specification which includes the frictional
requirements and gear wear requirements. This oil is offered in several viscosity grades for maximum component life at high ambient temperatures and for heavy-duty
NOTICE This oil is formulated for transmissions and drive trains only, and should not be used in engines. Shortened engine life will result.
Note: Do not use the Caterpillar Gear Oil in the machines that are listed above. The Gear Oil can cause seal material to fall. The seal material can also leak. The Gear Oil
may not be compatible with friction materials. The oil can reduce the efficiency of the transmission and the brake performance.
Note: Multigrade oils are not blended by Caterpillar for use in transmissions. Multigrade oils which use high molecular weight polymers as polymer viscosity index
improvers lose the viscosity effectiveness by temporary shear of the polymer viscosity index improver and by permanent shear of the polymer viscosity index improver.
Multigrade oils are not recommended for these compartments. The TO-4 oil specifications do not include a test for the shear stability of multigrade oil. Multigrade
oils with adequate shear stability may be available in the future.
Commercial TransmissionDrive Train Oils
If Caterpillar TransmissionDrive Train Oil is not used, commercial oils that meet the TO- 4 specification must be used:
