A sample of transmission fluid collected from a 92nd Logistics Readiness Squadron truck is analyzed at Fairchild Air Force Base, Washington, Nov. 4, 2019. Transmission fluid is just one of multiple machine oils the Micro Lab 40 Series is capable of analyzing to mitigate potential unnecessary routine oil changes, predict equipment failures to prevent future damage to vehicles and save money and man-hours.
