Lubrication System
The Engine Crankcase Fluid - 1 (ECF-1) specification has been introducedby Caterpillar in order to provide additional performance to the oils that are marketed 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 latestedition 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 manufacturers whose products meet the specification requirements.
CaterpillarDiesel 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.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) (SAE 10W-30)
Cat DEO (Diesel Engine Oil) (SAE 15W-40)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.Cat DEO multigrade oil is available in various viscosity grades that include SAE 10W-30 and SAE 15W-40. In order to choose the correct oil viscosity to use for the ambient temperature, refer to the tables for "Lubricant Viscosities for Ambient Temperatures" (Maintenance Section). Multigrade oils provide the correct viscosity for a broad range of operating temperatures.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.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.
