TP-6071 3/008 Section 2 Scheduled Maintenance
2.2 Lubrication System
The selection of engine oil is very important to a diesel
engine. If an unsuitable oil is used or an oil change is
neglected, it may result in damage and a shorter engine
life. Oil must meet the API classification of CD or CC.
Recommended SAE viscosity designation for given
temperature ranges is listed in Figure 2-1.
Note: Failure to observe these standards may cause
inadequate lubrication or oil pressure and cold
starting difficulties.
