Responsibilities of the Oil Company
Performance - The performance of the oil is the responsibility of the oil company. The oil must maintain stable oil control and the oil must control deposits in the combustion chamber and in the crankcase. Engine service life must be maintained at the predicted stage for the particular engine application.Supply - The supply of the oil is the responsibility of the oil company. If special storage and/or shipping is required, the oil company should cover the cost of those items.Oil and fuel analysis - During the evaluation, the oil company should pay for the cost of the oil and fuel analyses. The oil samples should be analyzed by the local Cat dealer in the S O S Services program. The data that is obtained from the oil analyses must be plotted in order to establish trends. The fuel should be analyzed periodically by an independent laboratory. Results of the oil and fuel analyses must be sent to the engine owner. The owner should review the data. Also, the owner should be allowed to keep records of the data.Hardware - If the oil is evaluated in a used engine, two new sets of these components must be installed before the Field Performance Evaluation: pistons, piston rings and cylinder liners. The cost should be covered by the oil company. These new components will be examined as part of the final inspection.Final Inspection - The cost of the final inspection should be paid by the oil company. The costs of additional downtime can also be part of the cost of inspection.

The cost includes the removal of storage tanks, special piping, flow meters, and instrumentation.Final Report - the oil company must prepare a final report that documents the following items:
Initial oil consumption and final oil consumption
The data on oil consumption must be recorded on a minimum schedule of every week. A chart of the data must be included in the final report.
Results of oil analyses
Oil changes
Replacement of oil filters
Results of fuel analyses
Fuel consumption or power output
Average engine speed (rpm)
The typical duty cycle
Close up photographs of the following components from two cylinders must also be included: pistons, piston rings before removal and after removal, piston rings after removal, cylinder liners, crankcase, top deck of the cylinder head, bottom deck of the cylinder head, inlet valves and exhaust valves.The final report should be confidential. The final report should be made available to the engine owner.Responsibilities of the Engine Owner
Engine for the Evaluation - The owner must
