Developed by Caterpillar and CFA, our fluids analysis program helps you detect problems before they lead to costly repairs and downtime. We recommend sampling fluid compartments every 250 hours and at each oil change. We also recommend sampling on-highway truck engines every 15,000 miles (25,000 km) and at each oil change.

Additionally, to realize the full condition monitoring and equipment management benefits of the CFA program, you should follow the best practices below.

1. Pull clean samples. Avoid external contamination such as dirt and water.
2. Fill out the sample information label completely. Provide accurate information about the equipment, the oil brand and type, and the operating time on the oil.
3. Send samples promptly to the laboratory. Avoid delay.
4. Build reliable operating trends by pulling samples on a regular basis – preferably every 250 operating hours.

You and your fluids analyst will develop a strong working relationship during the fluids analysis process. Never hesitate to promptly communicate any concerns, additional information, or repair activity.
