Lubricant Recommendations
Due to significant variations in the quality and in the performance of commercially available oils, Caterpillar recommends the following oils:
Cat DEO (Diesel Engine Oil) (10W-30)
Cat DEO (Diesel Engine Oil) (15W-40)Note: If Caterpillar DEO Multigrade is not used, use only commercial oils that meet the following classifications.
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.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.

Engine Oil Viscosities for Ambient Temperatures
Ambient Temperature
Viscosity Grade Minimum Maximum
SAE 0W-20 −40 °C (−40 °F) 10 °C (50 °F)
SAE 0W-30 −40 °C (−40 °F) 30 °C (86 °F)
SAE 0W-40 −40 °C (−40 °F) 40 °C (104 °F)
SAE 5W-30 −30 °C (−22 °F) 30 °C (86 °F)
SAE 5W-40 −30 °C (−22 °F) 50 °C (122 °F)
SAE 10W-30 −18 °C (0 °F) 40 °C (104 °F)
SAE 10W-40 −18 °C (0 °F) 50 °C (122 °F)
SAE 15W-40 −9.5 °C (15 °F) 50 °C (122 °F) Refer to Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations" for additional information that relates to lubricants.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.3508 Engine

Fuel Recommendations
In North America, diesel fuel that is identified as No. 1-D or No. 2-D in "ASTM D975" generally meet the specifications. These fuels are distilled from crude oil. Diesel fuels from other sources could exhibit detrimental properties that are not defined or controlled by this specification.Refer to Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations" for additional information that relates to diesel fuel.Cooling System
Coolant Recommendations
Do not use a commercial coolant/antifreeze that only meets the ASTM "D3306" specification. This type of coolant/antifreeze is made for light duty automotive applications.Use only the coolant/antifreeze that is recommended.
The following coolants are the primary types of coolants that are used in Caterpillar Engines:Preferred - Cat ELC (Extended Life Coolant) or a commercial extended life coolant that meets the Caterpillar EC-1 specificationAcceptable - Cat DEAC (Diese
