44 SEBU7901-01 Maintenance Section Refill Capacities Maintenance Section Cat DEO (Diesel Engine Oil) (SAE 10W-30) Cat DEO (Diesel Engine Oil) (SAE 15W-40) Refill Capacities Cat DEO multigrade oil is formulated with the correct amounts of detergents, dispersants, and alkalinity in order to provide superior performance in Caterpillar diesel engines. i02466201 Refill Capacities and Recommendations Cat DEO multigrade oil is available in various viscosity grades that include SAE 10W-30 and SAE 15W-40. Choose the correct oil viscosity for the ambient temperature by referring to table 4. Multigrade oils provide the correct viscosity for a broad range of operating temperatures. SMCS Code:
1348; 1395; 7560 NOTICE Every attempt is made to provide accurate, up-to-date information. By the use of this document, you agree that Caterpillar Inc. is not responsible for errors or omissions. Multigrade oils are effective in maintaining low oil consumption and low levels of piston deposits. Consult your Caterpillar dealer for part numbers and for available sizes of containers. NOTICE These recommendations are subject to change with- out prior notice. Contact your Caterpillar dealer for the most up to date recommendations. Note: Cat multigrade DEO exceeds the requirements of the ECF-1 specification.
Cat DEO SAE 15W-40 exceeds the performance requirements for the following API classifications: API CI-4, API CI-4 PLUS, API CH-4, API CG-4, and API CF. Cat DEO SAE 15W-40 oil also passes additional proprietary tests that include the following tests: sticking of the piston ring, stable oil control, tests for wear, and tests for soot. Proprietary tests help ensure that Caterpillar multigrade oil provides superior performance in Caterpillardiesel engines. In addition, Caterpillar multigrade oil exceeds many of the performance requirements of other manufacturers of diesel engines. Therefore, this oil is an excellent choice for many mixed fleets.
True high performance oil is produced by using a combination of the following factors: industry standard tests, proprietary tests, field tests, and prior experience with similar formulations. The design and the development of Caterpillar lubricants that are both high performance and high quality are based on these factors. Lubrication System NOTICE The Engine Crankcase Fluid - 1 (ECF-1) specifica- tion has been introducedby Caterpillar in order to pro- vide additional performance to the oils that are mar- keted under the American Petroleum Institute (API) categories of oil. The API Engine Oil Licensing and Certification System is recognized by Caterpillar.
For detailed information about this system, see the lat- estedition of the “API publication No. 1509”. Engine oils that bear the API symbol are authorized by API. The ECF-1 specification is applicable to those oil man- ufacturers whose products meet the specification re- quirements. Caterpillar Diesel Engine Oil (DEO) Caterpillar oils have been developed and tested in order to provide the full performance and service life that has been designed and built into Caterpillar engines. Cat DEO exceeds the requirements of the ECF-1 specification by passing four additional proprietary tests of diesel engine oil. Caterpillar oils are currently used to fill diesel engines at the factory.
These oils are offered by Caterpillar dealers for continued use when the engine oil is changed. Consult your Caterpillar dealer for more information on these oils. Commercial Oils Engine Crankcase Fluid Recommendations for all Caterpillar Diesel Engines Note: Commercial oils that conform to the requirements of the Caterpillar ECF-1 specification are acceptable but these oils are not preferred. Only commercial oils that meet the requirements of Caterpillar’s ECF-1 (Engine Crankcase Fluid specification - 1) are acceptable for use in Caterpillar commercial diesel engines.
API CH-4, API CI-4, and API CI-4 PLUS oils that have not met the requirements of Caterpillar’s ECF-1 specification may cause reduced engine life. Due to significant variations in the quality and in the performance of commercially available oils, Caterpillar makes the following recommendations:
