The information that is provided is the latest recommendations for Caterpillar on-highway truck engines. This information supersedes all previous recommendations which have been published for the Caterpillar on-highway truck engine that is covered by this publication.
These recommendations are subject to change without prior notice. Contact your Caterpillar dealer for the most up to date recommendations.
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. 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.Commercial Oils
Engine Crankcase Fluid Recommendations for all Caterpillar Diesel EnginesNote: 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 ECF-1 specification are acceptable for use in Caterpillar on-highway diesel engines. API CH-4, API CI-4, and API CI-4 PLUS oils that do not meet the requirements of the ECF-1 specification may cause reduced engine life.
Do not use API CF, API CF-4, or API CG-4 oils in Caterpillar on-highway diesel engines. Only use oils that meet the Caterpillar ECF-1 specification.
Failure to follow these oil recommendations can cause shortened engine service life due to deposits and/or excessive wear.
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.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 generally preferred over SAE 0W-20 or SAE 0W-30.Note: SAE 10W-30 is the preferred viscosity grade for this engine when the ambient temperature is above −18 °C (0 °F) and below 40 °C (104 °F).
