Maintenance programs test oil samples to improve equipment uptime, but compliance typically falls far short of the goal set by companies. Collecting samples and acting on those results are the cornerstones of a healthy oil analysis program. Yet few companies see the full potential of their program, and this creates a gap between the perceived benefits of oil analysis benefits, the real-world results and the potential ROI. Programs with proper leadership and support can close this gap through a combination of personnel, process and technological improvements.
