Lubricant Recommendations
Due to significant variations in the quality and in the performance of commercially available oils, Caterpillar recommends the following oils:
Caterpillar Diesel Engine Oil (SAE40)
Caterpillar Diesel Engine Oil (SAE30)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.
Table 1
Engine Oil Viscosity
SAE Viscosity Grade Ambient Temperature
Minimum Maximum
SAE 30 0 °C (32 °F) 40 °C (104 °F)
SAE 40 5 °C (41 °F) 50 °C (122 °F) Refer to Special Publication, SEBU7003, "3600 Diesel Engine Fluids Recommendations For Lubricants, Fuels, and Coolants" for additional information that relates to lubricants.Commercial Oils
Commercial engine oil for a 3600 Series diesel engine must have proof of performance in the Field Performance Evaluation. The TBN and the viscosity of the oil are also important factors.
The Field Performance Evaluation is required.
Field Performance - The commercial engine oil must demonstrate acceptable performance under controlled operating conditions for a minimum of 7000 hours in a 3600 or C280 Series diesel engine. For the evaluation of a particular oil, the oil company should arrange a field test with the owner of the engine. For a complete explanation of field evaluation for 3600 diesel engine oil, see Special Publication, SEBU7003, "3600 Series and
