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. 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 is formulated with the correct amounts of detergents, dispersants, and alkalinity in order to provide superior performance in Caterpillar Diesel Engines.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. Multigrade oils are also effective in maintaining low oil consumption and low levels of piston deposits.Cat DEO Multigrade can be used in other diesel engines and in gasoline engines. See the engine manufacturer's guide for the recommended specifications. Compare the specifications to the specifications of Cat DEO Multigrade. The current industry standards for Cat DEO are listed on the product label and on the data sheets for the product.Consult your Caterpillar dealer for part numbers and for available sizes of containers.Note: Cat DEO in SAE 15W-40 exceeds the performance requirements for the following API categories: CI-4, CH-4, CG-4, CF-4 and CF. Cat DEO Multigrade exceeds the requirements of the Caterpillar Engine Crankcase Fluid-1 (ECF-1) specification. Cat DEO in SAE 15W-40 passes the following proprietary tests: sticking of the piston ring, oil control tests, wear tests and soot tests. Proprietary tests help ensure that Caterpillar multigrade oil provides superior performance in Caterpillar Diesel Engines. In addition, Cat DEO Multigrade 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 with 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. Note: Non-Caterpillar commercial oils are second choice oils.Commercial Oils
In order to select the correct engine oil for the marine C6.6 genset, you must refer to table 1.

Engine Power Oil Specification Maintenance Interval
Less than 168 kW (225 hp) CH-4/CI-4 500 Hours
More than 168 kW (225 hp) CI-4 500 Hours Note: If Cat DEO Multigrade is not used, use only commercial oils that meet the following categories.
API CH-4 multigrade oils and API CI-4 multigrade oils are acceptable if the requirements of
