Scheduled Oil Sampling (S.O.S) is a process designed to turn fluid analysis data into valuable information and is the cornerstone program among Condition Monitoring Elements (CME). The Cat certified data interpreter identifies wear modes like Corrosion, Abrasion, Adhesive and Fatigue type. Viscosity and Additive Elements indicate whether oil formulation is accurate. After understanding various aspects about the equipment via Customer Support Engineer, the S.O.S lab prepares a case study of how failure may be prevented and repair cost reduced. All Yellow and Red Alert reports need to be followed up with the customer and corrective actions need to be taken in order to reduce the customers operating and ownership cost.
