Lube Oil Analyses—A Preventive Maintenance Tool for Marine Diesel Engines

A program of routine analyses is a preventive maintenance tool limited only by its own accuracy and by the extent to which test data and interpretations are utilized by the engine operator.

This discussion emphasizes the importance of the part played by the engine operator, and examines in familiar terms the methods and significance of the routine areas of analytical work. The conclusion demonstrates through graphic examples how the information developed through a dozen or more routine tests is collectively interpreted, relating lubricant condition to engine condition.
