A machine condition diagnostic system is provided wherein machine components or their immediate surroundings are labelled with indicator materials. A normal level of indicators in the lubricant will be established. The lubricant is monitored and periodically sampled to determine the presence of abnormal levels in the amount of indicator material. Since each component or components performing a similar function will be labelled with the same indicator, the presence of a particular indicator in abnormal amounts in the lubricant will direct the machine operator to the precise location requiring repair or replacement.
