Due to significant variations in the quality and in the performance of commercially available oils, Caterpillar recommends the following oils:
- Cat DEO (Diesel Engine Oil) (10W-30)
- Cat DEO (Diesel Engine Oil) (15W-40)
- Cat DEO-ULS (Diesel Engine Oil - Ultra Low Sulfur) (15W-40)
Note: Non-Caterpillar commercial oils are as a group second choice oils. This group of second choice oils are rated by performance.
| NOTICE |

|
Caterpillar does not warrant the quality or performance of non-Caterpillar fluids. |
Caterpillar developed the Engine Crankcase Fluid (ECF) specifications in order to ensure the availability of high performance commercial diesel engine oils. When the high performance commercial diesel engine oils are used properly, the availability of the high performance commercial diesel engine oils provides satisfactory life in the Cat Diesel Engines.
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 for use in Cat diesel engines that are covered by this Operation and Maintenance Manual. API category oils that have not met the requirements of at least one Cat ECF specification may cause reduced engine life.
- Commercial oils that meet the requirements of the Cat ECF-3 specification or meet the requirements of the API CJ-4 oil category are the preferred commercial alternative oils for use in all Cat diesel engines that are covered by this Operation and Maintenance Manual
Oils that meet the requirements of the CJ-4 API category are compliant with the Cat ECF-3 specification.
The following categories of oils are not approved for use in your Caterpillar Engine: API CF, API CF-4 and API CG-4.
| NOTICE |
|---|
|
Do not use single grade API CF oils or multigrade API CF oils in Caterpillar 3500 Series Engines. |
| NOTICE |

|
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. |
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. To determine the oil viscosity that is required for starting a cold soaked engine, refer to the minimum temperature in Table 1. To select the oil viscosity for operation at the highest anticipated ambient temperature, refer to the maximum temperature in the Table. Use the highest oil viscosity that is available in order to meet the required temperature during start-up.

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 oil
These 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. 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 person at your Caterpillar dealership should make the final analysis.
| NOTICE |
|---|
|
Always use a designated pump for oil sampling, and use a separate designated pump for coolant sampling. Using the same pump for both types of samples may contaminate the samples that are being drawn. This contaminate may cause a false analysis and an incorrect interpretation that could lead to concerns by both dealers and customers. |
Refer to Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations" in order to obtain additional information about S·O·S Services oil analysis. You can also contact your local Caterpillar dealer for additional information concerning the S·O·S Services Oil Analysis program.
The capacity of the engine lubrication system includes the capacity of the oil filters that are installed at the factory. Auxiliary oil filter systems (if equipped) will require additional oil. Refer to the specifications that are provided by the OEM of the auxiliary oil filter system.
