Lubricant Recommendations
Cat DEO (Diesel Engine Oil)
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)Commercial Oils
Caterpillar does not warrant the quality or performance of non-Caterpillar fluids.
Note: If Cat DEO multigrade is not used, use only commercial oils that meet the following categories/specifications:
API CH-4 multigrade oils and API CI-4 multigrade oils are acceptable if the requirements of Caterpillar's Engine Crankcase Fluid -1 (ECF-1) specification are met. CH-4 oils and CI-4 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.Viscosity of Engine Oil
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. To determine the oil viscosity that is required for starting a cold soaked engine, refer to the minimum temperature in Table 1. To select the oil viscosity for operation at the highest anticipated ambient temperature, refer to the maximum temperature in the Table. Use the highest oil viscosity that is available in order to meet the required temperature during start-up.

Note: Decrease the interval between oil changes by 20 percent and/or increase the API service classification of the oil for engines that operate at high load factors of 80 percent or more for extended periods of time. Refer to Caterpillar Publication, PEDP7035, "S O S Fluid Analysis Interpetation Guide" in order to fully understand optimizing oil change intervals.Refer to Operation and maintenance Manual, "Engine Oil and Filter - Change" for more information about oil change intervals .Lubricant Capacities
The capacity of the engine lubrication system includes the capacity of the oil filters that are installed at the factory. Auxiliary oil filter systems (if equipped) will require additional oil. Refer to the specifications that are provided by the OEM of the auxiliary oil filter system. 3512B Engine
