When the department kept running out of oil at the end of each quarter, Service Manager Brent Whetstone of Ellens Equipment discovered a discrepancy between how much fluid was used vs. how much was available. Having identified the problem, Ellens Equipment was able to determine a number of solutions, such as changing the volume metrics by which the oil was purchased as well as fluid counters for the pumps. By spending more on preventative measures, the company was able to save a larger sum in the long run.
