Note: Instructions for the installation of the filter are printed on the side of each Caterpillar spin-on filter. For non-Caterpillar filters, refer to the installation instructions that are provided by the supplier of the filter.Diesel Engine Oil
For more information, refer to Special Publication, SEBU6251, "Caterpillar Commercial Engine Fluids Recommendations".Cat DEO-ULS or oils that meet the Cat ECF-3 specification and the API CJ-4 specification are required for the following applications:Caterpillar 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. 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 significant variations in the quality and in the performance of commercially available oils, Caterpillar makes the following recommendations:
Cat DEO-ULS SYN (Multigrade Engine Oil - Ultralow Sulfur Synthetic) SAE 0W40
Cat DEO-ULS (Multigrade Diesel Engine Oil - Ultralow Sulfur)
Cat DEO-ULS SYN (Multigrade Diesel Engine Oil - Ultralow Sulfur Synthetic)
Cat Arctic DEO SYN (Synthetic Diesel Engine Oil) SAE 0W-30Commercial Oil
Note: Non-Caterpillar commercial oils are not the best oils for your engine.
Caterpillar does not warrant the quality or performance of non-Caterpillar fluids.
Note: If Cat 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-3 specification are acceptable for use. Oils in the API category that does not meet the requirements of at least Cat ECF-3 specification will cause reduced engine life.
The preferred commercial oils meet at least one of the following requirements: Cat ECF-3 specification and API CJ-4.When an oil is compliant with the requirements of the API CJ-4 category, the oil is compliant with the Cat ECF-3 specification.In selecting oil for any engine application, both of the following must be satisfied: the oil viscosity and the category of oil performance or the specification for oil performance . 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 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.Note: Generally, use the highest oil viscosity that is available to meet the requirement for the temperature at start-up.If ambient temperature conditions at engine start-up require the use of multigrade SAE 0W oil, SAE 0W-40 viscosity grade is preferred over SAE 0W-30.Note: SAE 10W-30 is the preferred viscosity grade for the following diesel engines when the ambient temperature is above −18 °C (0 °F), and below 40 °C (104 °F).

SAE 0W-30 −40 °C (−40 °F) 30 °C (86 °F)
SAE 0W-40 −40 °C (−40 °F) 40 °C (104 °F)
SAE 5W-30 −30 °C (−22 °F) 30 °C (86 °F)
SAE 5W-40 −30 °C (−22 °F) 50 °C (122 °F)
SAE 10W-30 −18 °C (0 °F) 40 °C (104 °F)
SAE 10W-40 −18 °C (0 °F) 50 °C (122 °F)

(1) Refer to this Special Publication, "Engine Oil" article for recommendations of diesel engine oil type.
(2) Supplemental heat is recommended for cold soaked starts below the minimum ambient temperature. Supplemental heat may be necessary for cold soaked starts that are above the minimum temperature, depending on the parasitic load and other factors. Cold soaked starts occur when the engine has not been operated for a time. The cold soaked start allows the oil to become more viscous due to cooler ambient temperatures.S O S Services Oil Analysis
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 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.
