Rationale

The in-service monitoring of diesel engine oils has long been recognized by the diesel engine industry as being necessary to ensure long operation of diesel engines. This practice is designed to assist the user to validate the condition of the lubricant through its life cycle by carrying out a meaningful program of sampling and testing of oils in service. This practice is performed in order to collect data and monitor trends which suggest any signs of lubricant deterioration and to ensure a safe, reliable, and cost-effective operation of the diesel engine.
