These recommendations are subject to change without notice. Contact your local Cat dealer for the most up-to-date recommendations.
Note: Instructions for the installation of the filter are printed on the side of each Cat spin-on filter. For non-Cat filters, refer to the installation instructions that are provided by the supplier of the filter.For more information, refer to Special Publication, SEBU6251, "Caterpillar Commercial Engine Fluids Recommendations".Diesel Engine Oil
Faulty engine coolant temperature regulators, or operating with light loads, short operation cycles, excessive idling, or operating in applications were normal operating temperature is seldom reached can contribute to excessive water in the crankcase oil. Corrosive damage, piston deposits and increased oil consumption can result. If a complete oil analysis program is not followed or if the results are ignored, the potential for corrosive damage and piston deposits increases.
Cat Diesel Engine Oil (Cat DEO)
Cat oils have been developed and tested in order to provide the full performance and service life that has been designed and built into Cat engines. Cat oils are currently used to fill diesel engines at the factory. These oils are offered by Cat dealers for continued use when the engine oil is changed. Consult your Cat dealer for more information on these oils.Due to significant variations in the quality and in the performance of commercially available oils, Caterpillar makes the following recommendations:
Cat DEO (Diesel Engine Oil) (10W-30)
Cat DEO (Diesel Engine Oil) (15W-40)
Cat DEO-ULS (Diesel Engine Oil - Ultralow Sulfur) (10W-30)
Cat DEO-ULS (Diesel Engine Oil - Ultralow Sulfur) (15W-40)Note: Cat DEO-ULS multigrade is the preferred oil for use in all Cat diesel engines for which SAE 15W-40 is the preferred viscosity grade.Commercial Oil
Note: Non-Cat commercial oils are not the best oils for your engine.
Caterpillar does not warrant the quality or performance of non-Cat fluids.
The three current Cat ECF specifications are: Cat ECF-1-a, Cat ECF-2 and Cat ECF-3. Each higher Cat ECF specification provides increased performance over lower Cat ECF specifications.Note: The Cat ECF-1-a and Cat ECF-2 specifications replaced the Cat ECF-1 specification on 1 March 2007.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. API category of oils that have not met the requirements of at least one Cat ECF specification may cause reduced engine life.
The preferred commercial oils meet at least one of the following requirements: Cat ECF-3 specification and API CJ-4.Oils that meet the requirements of the API CJ-4 category are compliant with the Cat ECF-3 specification.The following categories of oils are not approved for use in your Cat Engine:API CF, API CF-4 and API CG-4.In selecting oil for any engine application, both of the following must be satisfied: the oil viscosity and the oil performance category or the oil performance specification.
