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) (SAE40)
Cat DEO Diesel Engine Oil (SAE30)The proper SAE viscosity grade of oil is determined by the minimum ambient temperature during cold engine start-up. The proper SAE viscosity grade of oil is also determined by 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.

50 °C (122 °F)    Refer to Special Publication, SEBU7003, "3600 Series and C280 Series Diesel Engine Fluids Recommendations" for additional information that relates to lubricants.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, SEBU7003, "3600 Series and C280 Series Diesel Engine Fluids Recommendations" for additional information that relates to diesel fuel.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 Cat Engines:Preferred - Cat ELC (Extended Life Coolant) or a commercial extended life coolant that meets the Cat EC-1 specificationAcceptable - Cat DEAC (Diesel Engine Antifreeze/Coolant) or a commercial heavy-duty antifreeze/coolant solution that meets "ASTM D4985" or "ASTM D5345" specificationsCaterpillar recommends a 1:1 mixture of water and glycol. This mixture will provide optimum heavy-duty performance as an antifreeze/coolant solution.Note: Cat DEAC DOES NOT require a treatment with an SCA at the initial fill. The commercial heavy-duty antifreeze/coolant solution that meets "ASTM D4985" or "ASTM D5345" specifications MAY require a treatment with an SCA at the initial fill. Read the label or the instructions that are provided by the OEM of the product.In stationary engine applications and marine engine applications that do not require protection from boiling or freezing, a mixture of SCA and water is acceptable. Caterpillar recommends a minimum of 6 percent to a maximum of 8 percent SCA concentration in those cooling systems. Distilled water or deionized water is preferred. Water which has the required properties may be used. For the water properties, refer to Special Publication, SEBU7003, "3600 Series and C280 Series Diesel Engine Fluids Recommendations" for additional information that relates to coolant.Note: Table 2 is a
