Cat DEO-ULS (Diesel Engine Oil - Ultra Low Sulfur)
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 the additional full-scale proprietary engine testing required of Cat DEO-ULS and due to significant variations in the quality and in the performance of commercially available oils, Caterpillar makes the following recommendation for:
Cat DEO-ULS (Diesel Engine Oil - Ultra Low Sulfur) (15W-40 and 10W-30)Cat DEO-ULS 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.Note: Cat DEO-ULS oil is the preferred oil for use in ALL Cat diesel engines that are covered by this Special Publication. Commercial alternative diesel engine oils are, as a group, second choice oils.Cat DEO-ULS or oils that meet the Cat ECF-3 specification and the API CJ-4 oil category are required for use in nonroad Tier 4 United States Environmental Protection Agency (U.S. EPA) certified engines that are equipped with aftertreatment devices.Cat DEO-ULS or oils that meet the Cat ECF-3 specification and the API CJ-4 are required for use in the applications listed below. If oils meeting the Cat ECF-3 specification and the 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 CJ-4 standard engine performance tests. Consult your oil supplier when considering use of an oil that is not Cat ECF-3 or API CJ-4 qualified.
Nonroad EU Stage IIIB and IV type-approved engines that are equipped with aftertreatment devices
Nonroad Japan Step 4 approved engines that are equipped with aftertreatment devicesCat DEO-ULS and oils meeting the Cat ECF-3 specification and the API CJ-4 and ACEA E9 oil categories have the following chemical limits:
1 percent maximum sulfated ash
0.12 percent maximum phosphorous
0.4 percent maximum sulfurThe chemical limits were developed in order to maintain the expected aftertreatment devices life, performance, and service intervals. Use of oils other than Cat DEO-ULS or oils that do not meet the Cat ECF-3 specification and the API CJ-4 oil category (and/or ACEA E9 category for EU and Japan specific applications listed above) in aftertreatment-equipped engines can negatively affect performance of the aftertreatment devices, can contribute to Diesel Particulate Filter (DPF) plugging and/or can cause the need for more frequent DPF ash service intervals. Refer to your engine-specific Operation and Maintenance Manual, and refer to your aftertreatment device documentation, if available, for additional guidance.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.Cat DEO-ULS is recommended for all pre-Tier 4 engines
