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 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 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 CJ-4 PLUS, API CH-4, and API CF. Cat DEO-ULS multigrade is compatible for use in aftermarket device equipped engines.Cat DEO multigrade exceeds the requirements of the following Cat engine crankcase fluid 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.Failure to meet the listed requirements will damage aftertreatment-equipped engines and can negatively impact the performance of the aftertreatment devices.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 to provide superior performance in Cat diesel engines where recommended for use.When fuels of sulfur level of 0.1% (1000 ppm) or higher are used, Cat DEO-ULS may be used if S O S oil analysis program is followed. Base the oil change interval on the oil analysis.TIer IV/EU Stage V
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 or API 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 devise's life, performance, and service interval. If oils meeting the Cat ECF-3 specification and the API CK-4 and API 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.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.

Oil Renewal systems should not be used in engines equipped with aftertreatment systems. Reduced life or damage to the aftertreatment may occur.
S O S Services Oil Analysis
These recommendations are subject to change without prior notice. Contact your Caterpillar dealer for the most up to date recommendations.
Caterpillar has developed a maintenance tool that evaluates oil degradation. the maintenance management also detects the early signs of wear on internal components. The Cat tool for oil analysis is called S O S Oil Analysis and the tool is part of the S O S Services program. S O S Oil Analysis divides oil analysis into four categories:
Component wear rate
Oil condition
Oil contamination
Identification of oilThese four types of analysis are used to monitor the condition of your equipment. The four types of analysis will also help you identify potential problems. A properly administered S O S Oil Analysis program will reduce repair costs and the program will lessen the impact of downtime.The S O S Oil Analysis program uses a wide range of tests to determine the condition of the oil and the lubricated compartment. Guidelines that are based on experience and a correlation to failures have been established for these tests. Exceeding one or more of these guidelines could indicate serious fluid degradation or a pending component failure. A trained pers
