Engine oil is an important and the most essential part of machine system. Oil monitoring is a tool to determine lubricant useful life. It can be either performance testing or oil condition monitoring. Knowledge of the system's failure modes is essential for cost-effective oil monitoring. Contamination occurs by mating contact inside the engine chamber. In the present work used CH415W40 engine oil were monitored under bichromatic microscope to observe the contamination and surfaces wear micrograph. According to the observation, rubbing, cutting, fatigue, corrosion, abrasive and scuffing wear modes were observed.
