Oil too heavy may cause the following conditions in the system:
1.
system pressure drop;
2.
increased system temperature;
3.
sluggish system operation;
4.
low mechanical efficiency;
5.
higher power consumption.
Excessive wear in the system may cause a loss in volumetric efficiency, and may cause shutdowns for
maintenance. An efficient antiwear oil protects the components against rusting.
Selection of the proper oil is a requirement for satisfactory system performance.
