ECF-1 Specification Diesel Engine Oils
The Engine Crankcase Fluid - 1 (ECF-1) specification has been introduced by Caterpillar in order to provide additional performance to the oils that are marketed under the American Petroleum Institute (API) oil classifications. The ECF-1 specification is applicable to those products that meet the requirements of the specification.

Specifications and/or Classifications
Specification and/or Classification Precombustion Chamber Direct Injection(1)
Cat ECF-1(2) Recommended Recommended
CG-4(3) Acceptable at a Reduced Drain Interval Acceptable at a Reduced Drain Interval
CF-4(4), CF-2(5) Unacceptable Unacceptable
CF(6) Acceptable Unacceptable
CE, CD, CC, and CD-2(7) Obsolete Obsolete
(1) Most Caterpillar engines that were built after 1991 are direct injection (DI) diesel engines. Diesel engine oils that only have a single viscosity grade are not acceptable for use in Caterpillar DI diesel engines. Multigrade diesel engine oils are required.
(2) API CI-4, CI-4 PLUS, and CH-4 oils are acceptable if the requirements of the Caterpillar ECF-1 specification are met. CI-4, CI-4 PLUS, and CH-4 oils that have not met the requirements of Caterpillar's ECF-1 specification may cause reduced engine life.
(3) API CG-4 oils are acceptable for all Caterpillar diesel engines. When API CG-4 oils are used, the oil drain interval should not exceed the standard oil drain interval for your engine.
(4) API CF-4 oils are not recommended for Caterpillar diesel engines.
(5) API CF-2 and CD-2 oils are classifications for two-cycle diesel engines. Caterpillar does not sell engines that use API CF-2 and CD-2 oils.
(6) API CF oils are not recommended for Caterpillar direct injection (DI) diesel engines.
(7) API has not authorized the CC, CD, CD-2, and CE classifications since 1 January 1996.Note: When oil meets more than one API classification, the applicable footnote is determined by the highest API classification that is met.Example - An oil that meets both the API CG-4 and the API CF oil classifications. In this case, the API CG-4 footnote applies.Cat DEO (Diesel Engine Oil)
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) (10W-30)
Cat DEO (Diesel Engine Oil) (15W-40)Cat DEO multigrade is available in various viscosity grades that include SAE 10W-30 and SAE 15W-40. To choose the correct viscosity grade for the ambient temperature, see Table 2. Multigrade oils provide the correct viscosity for a broad range of operating temperatures.Consult your Caterpillar dealer for part numbers and for available sizes of containers.Commercial Oils
Note: If Caterpillar DEO multigrade is not used, use only commercial oils that meet the following classifications.
Only commercial oils that meet the requirements of Caterpillar's ECF-1 specification are acceptable for use in Caterpillar diesel engines. API CH-4, CI-4, and CI-4 PLUS oils that have not met the requirements of Caterpillar's ECF-1 Specification may cause reduced engine life.
API CG-4 multigrade oils are acceptable for all Caterpillar diesel engines. When the API CG-4 oils are used, the oil drain interval should not exceed the standard oil drain interval for your engine.Note: Do not use API CF-4 oils in Caterpillar diesel engines.
In selecting oil for any engine application, both the oil viscosity and oil performance classification/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.
Failure to follow these oil recommendations can cause shortened engine service life due to deposits and/or excessive wear.
Note: Refer to Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations" for additional information that relates to lubrication for your engine.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 2 (minimum temperature) in order to determine the required oil viscosity for starting a cold engine.Refer to Table 2 (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-20 or SAE 0W-30.
