These recommendations are subject to change without prior notice. Contact your Caterpillar dealer for the most up to date recommendations.
Refer to Special Publication, SEBU6251, "Cat Commercial Diesel Engine Fluids Recommendations" for additional information.Refer to this Operation and Maintenance Manual, "Severe Service Application" for information about operating an engine in a severe service application.Note: Instructions for the installation of the filter are printed on the side of each Cat spin-on filter. For filters that are not Cat filters, refer to the installation instructions that are provided by the supplier of the filter.Diesel Engine Oil
Cat DEO (Diesel Engine Oil)
Due to significant variations in the quality and in the performance of commercially available oils, Caterpillar makes the following recommendations:
Cat DEO-ULS (Diesel Engine Oil Ultra Low Sulfur) (SAE 5W-40)
Cat DEO-ULS (Diesel Engine Oil Ultra Low Sulfur) (SAE 10W-30)
Cat DEO-ULS (Diesel Engine Oil Ultra Low Sulfur) (SAE 15W-40)Engine Oil
Cat DEO-ULS multigrade exceeds the requirements of the following Cat Engine Crankcase Fluid (ECF) specifications: Cat ECF-1-a, Cat ECF-2, and Cat ECF-3. Cat DEO-ULS multigrade exceeds the performance requirements for the following API oil categories: API CK-4, API CJ-4, API CI-4, API CI-4 PLUS, API CH-4, and API CF. Cat DEO-ULS multigrade is compatible for use in aftertreatment device equipped engines.Cat DEO multigrade exceeds the requirements of the following Cat Engine Crankcase Fluid (ECF) Specifications: Cat ECF-1-a and Cat ECF-2. Cat DEO multigrade exceeds the performance requirements for the following American Petroleum Institute (API) oil categories: API CI-4, API CI-4 PLUS, API CH-4, and API CF. The availability ofCatDEO multigrade exceeding the noted requirements will vary by region. Cat DEO and oils meeting Cat EFC-1-a and /or Cat ECF-2 are not compatible for use in aftertreatment device equipped engines.Non-Tier IV
Cat oils have been developed and tested to provide the full performance and life that has been designed and built into Cat engines.Cat DEO-ULS multigrade and Cat DEO multigrade oils are formulated with the correct amounts of detergents, dispersants, and alkalinity in order to provide superior performance in Cat diesel engines where recommended for use.

Cat oils have been developed and tested to provide the full performance and life that has been designed and built into Cat engines.Cat DEO-ULS or oils that meet the Cat ECF-3 specification and the API CK-4 orAPI CJ-4 are required for use in the applications listed below. Cat DEO-ULS and oils meeting Cat ECF-3 specification and the API CJ-4 and ACEA E9 oil categories have been developed with limited sulfated ash, phosphorus, and sulfur. These chemical limits are designed to maintain the expected aftertreatment devices life, performance, and service interval. If oils meeting the Cat ECF-3 specification and the API CK-4 andAPI CJ-4 specifications are not available, oils meeting ACEA E9 may be used. ACEA E9 oils meet the chemical limits designed to maintain aftertreatment device life. ACEA E9 oils are validated using some but not all ECF-3 and API CK-4 and API CJ-4 standard engine performance tests. Consult your oil supplier when considering use of an oil that is not Cat ECF-3 API CJ-4, or API CK-4 qualified.Failure to meet the listed requirements will damage aftertreatment-equipped engines and can negatively impact the performance of the aftertreatment devices. The Diesel Particulate Filter (DPF) will plug sooner and require more frequent DPF ash service intervals.Typical aftertreatment systems include the following:
Diesel Particulate Filters (DPF)
Diesel Oxidation Catalysts (DOC)
Selective Catalytic Reduction (SCR)
Lean NOx Traps (LNT)Other systems may apply.
