Note: Note: Refer to the latest edition of Special Publication, SEBU6251, "Caterpillar Commercial Engine Fluids Recommendations" for additional information. Contact your Cat dealer in order to confirm that you have the newest recommendations for fluids.Note: Instructions for the installation of the filter are printed on the side of each Caterpillar spin-on filter. For filters that are not Cat filters, refer to the installation instructions that are provided by the supplier of the filter.Lubrication System
Note: Instructions for the installation of the filter are printed on the side of each Cat spin-on filter. For non-Caterpillar filters, refer to the installation instructions that are provided by the supplier of the filter.Lubricant Recommendations
Due to significant variations in the quality and in the performance of commercially available oils, Caterpillar recommends the following oils:
Cat DEO (Diesel Engine Oil) (10W-30)
Cat DEO (Diesel Engine Oil) (15W-40)
Cat DEO-ULS (Diesel Engine Oil - Ultra Low Sulfur) (15W-40) (SAE 10W-30 is only available in bulk quantities.)Note: Cat DEO-ULS and Cat DEO multigrade oils are the preferred oils for use in all Cat Diesel Engines.Commercial Oils
Caterpillar does not warrant the quality or performance of non-Caterpillar fluids.
Note: Non-Caterpillar commercial oils are as a group second choice oils. Within this grouping of second choice oils, there are different levels of performance.Caterpillar developed the Engine Crankcase Fluid (ECF) specifications in order to ensure the availability of high performance commercial diesel engine oils. When the high performance commercial diesel engine oils are used properly, the availability of high performance commercial diesel engine oils provide satisfactory life in the Cat Diesel Engines. Note: If Cat DEO multigrade or DEO-ULS multigrade oils are not used, use only commercial oils that meet the following categories/specifications:
Commercial oils that meet the requirements of the Cat ECF-1-a, Cat ECF-2, and/or the Cat ECF-3 specification are acceptable for use in Cat Diesel Engines that are covered by this Operation and Maintenance Manual. The API category of oils that have not met the requirements of at least one Cat ECF specification may cause reduced engine life.
Commercial oils that meet the requirements of the Cat ECF-3 specification or meet the requirements of the API CJ-4 oil category are the preferred commercial alternative oils for use in all Cat Diesel Engines that are covered by this Operation and Maintenance ManualOils that meet the requirements of the CJ-4 API category are compliant with the Cat ECF-3 specification.
Do not use single grade API CF oils or multigrade API CF oils in Caterpillar3500 Series Engines.
Engine Oil Viscosities
In selecting oil for any engine application, both the oil viscosity and oil performance category/specification as specified by the engine manufacturer must be defined and satisfied. Using only one of these parameters will not sufficiently define oil for an engine application.
The proper SAE viscosity grade of
