Failure to follow these oil recommendations can cause shortened engine service life due to deposits and/or excessive wear.
Total Base Number (TBN) and Fuel Sulfur Levels for Direct Injection (DI) Diesel Engines
The Total Base Number (TBN) for an oil depends on the fuel sulfur level. For direct injection engines that use distillate fuel, the minimum TBN must be 10 times the fuel sulfur level. The TBN is determined by the "ASTM D2896" procedure. The minimum TBN of the oil is 5 regardless of a low fuel sulfur level. Illustration 1 demonstrates the TBN.

(1) TBN of new oil
(2) Change the used oil when the TBN reaches this level. Use the following guidelines for fuel sulfur levels that exceed 1.5 percent:
Choose an oil with the highest TBN that meets one of these classifications:
API CG-4
API CH-4
API CI-4Note: API CH-4 oils and API CI-4 oils are acceptable if the requirements of Caterpillar's ECF-1 (Engine Crankcase Fluid specification-1) 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.
Reduce the oil change interval. Base the oil change interval on the oil analysis. Ensure that the oil analysis includes the condition of the oil and a wear metal analysis. Excessive piston deposits can be produced by an oil with a high TBN. These deposits can lead to a loss of control of the oil consumption and to the polishing of the cylinder bore.
Operating Direct Injection (DI) diesel engines with fuel sulfur levels over 1.0 percent may require shortened oil change intervals in order to help maintain adequate wear protection.
Lubricant Viscosity Recommendations for Direct Injection (DI) Diesel Engines
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. Refer to Table 1 (minimum temperature) in order to determine the required oil viscosity for starting a cold engine.Refer to Table 1 (maximum temperature) in order to select the oil viscosity for engine operation at the highest ambient temperature that is anticipated.Note: Generally, use the highest oil viscosity that is available to meet the requirement for the temperature at start-up.If ambient temperature conditions at engine start-up require the use of multigrade SAE 0W oil, SAE 0W-40 viscosity grade is generally preferred over SAE 0W-20 or SAE 0W-30.Note: SAE 10W-30 is the preferred viscosity grade for the following diesel engines when the ambient temperature is above −18 °C (0 °F), and below 40 °C (104 °F).
