Note: Note: Refer to the latest edition of Special Publication, SEBU6385, "Caterpillar On-highway Diesel Engine Fluids Recommendations" for additional information. Contact your Caterpillar 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 Caterpillar filters, refer to the installation instructions that are provided by the supplier of the filter.Diesel Engine Oil
Cat DEO (Diesel Engine Oil)
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.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) (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 on-highway engines.Note: For optimum engine system performance of DPF equipped Cat diesel engines, the use of Cat DEO-ULS is strongly recommended. For optimum engine system performance of DPF equipped Cat diesel engines, the use of ultralow sulfur diesel fuel (ULSD) is required.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 tiered levels of performance.Caterpillar developed the Engine Crankcase Fluid (ECF) specifications to ensure the availability of high performance commercial diesel engine oils in order to provide satisfactory life and performance in Cat diesel engines where recommended for use.There are three current Cat ECF specifications: Cat ECF-1-a, Cat ECF-2 and Cat ECF-3. Each higher Cat ECF specification provides increased performance over lower Cat ECF specifications. For example, Cat ECF-3 provides higher performance than Cat ECF-2 and Cat ECF-3 provides much higher performance than Cat ECF-1-a. After Cat DEO-ULS and Cat DEO, commercial oils that meet the Cat ECF-3 specification are preferred oils for use in Cat On-highway Engines. Oils that meet the API CJ-4 oil category requirements are compliant with the Cat ECF-3 specification.Commercial oils that meet the requirements of the Cat ECF-1-a specification and commercial oils that meet the requirements of the Cat ECF-2 specification are acceptable for use in theCaterpillar On-highway Engines that are covered by this publication. API category oils that have not met the requirements of at least one Cat ECF specification may cause reduced engine life. Use of oil that does not meet the Cat ECF-3 specification and the API CJ-4 oil category may require more frequent DPF cleaning cycles and may contribute to DPF plugging. When the recommended and preferred Cat DEO-ULS is not used, it is strongly recommended that DPF equipped engines use oil that meets the Cat ECF-3 specification and the API CJ-4 oil category.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.Lubricant Viscosity Recommendations
The proper SAE viscosity grade of oil is determined by the minimum ambient temperature during cold engine start-up, and the maximum ambient temperature during engine operation. Refer to Table 1 (minimum temperature) in order to determine the required oil viscosity for starting a cold engine.Refer to Table 1 (maximum temperature) in order to select the oil viscosity for engine operation at the highest ambient temperature that is anticipated.
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.

Caterpillar has developed a maintenance tool that evaluates oil degradation. The maintenance management also detects the early signs of wear on internal components. The Caterpillar 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 condition of the lubricated compartment.
