Obtain the oil samples as close as possible to the standard intervals. In order to receive the full effect of S·O·S oil analysis, you must establish a consistent trend of data. In order to establish a pertinent history of data, perform consistent scheduled oil samplings that are evenly spaced.
Consult your Caterpillar dealer for complete information and assistance about the S·O·S oil analysis program.
