Aftermarket Oil Additives
Cat does not recommend the use of aftermarket additives in oil. Aftermarket additives are not necessary in order to achieve the maximum service life of the engine or rated performance of the engine. 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 help provide performance characteristics that meet industry standards.
There are no industry standard tests that evaluate the performance or the compatibility of aftermarket additives in finished oil. Aftermarket additives may not be compatible with the finished oil additive package, which could lower the performance of the finished oil. The aftermarket additive could fail to mix with the finished oil and produce sludge in the crankcase. Cat discourages the use of aftermarket additives in finished oils.
To achieve the best performance from a Cat engine, conform to the following guidelines:
- Select the proper Cat oil or commercial oil. Refer to the "Lubricant Specifications" section of this Special Publication.
- Refer to the "Lubricant Viscosities for Ambient Temperatures" table in this Special Publication in order to find the correct oil viscosity grade for your engine.
- At the specified interval, service the engine compartment. Use appropriate new oil and install an appropriate new oil filter.
- Perform maintenance at the intervals that are specified in the Operation and Maintenance Manual, "Maintenance Interval Schedule".
