SOS Fluid Analysis Lab
Cat SOS Services fluid analysis — oil, coolant, and fuel analysis with 24-hour turnaround and expert Caterpillar-trained recommendations.
Schedule ServiceCat SOS Services is a fluid analysis process developed by Caterpillar to monitor the overall condition of equipment. Our lab analyzes fluids from all makes and models using the Cat SOS process. Technicians run numerous tests to determine the presence of abnormal wear, oil condition, oil contamination, and other issues.
Test data is used to monitor the machine health of engines, transmissions, hydraulic systems, final drives, gas compression engines, compressors, and more. Our commitment is to maintain your machine's overall health and prevent small problems from turning into catastrophic issues. We help customers attain low operating costs, peak performance, and top resale value.
With half a century of experience in fluid testing, Cat SOS Services is the world's largest in-house OEM fluid analysis program. We can accurately predict component failures before they happen, and we continue to innovate to get you reliable, valuable information — fast.
