Obtaining an Oil Sample

Service Procedure for the FS-2500
 
 
Change the oil and full flow filter on the engine that you will be installing the FS-2500. If you plan on using an oil analysis program, take a sample of your terminal oil. If you intend on extending your oil drain interval, Filtration Solutions strongly recommends using oil analysis to verify your oil’s condition. Install the FS-2500. Once the system is installed the service for the FS-2500 is as follows:
 
INSTRUCTIONS FOR MAINTAINING THE FS-2500 BYPASS FILTRATION SYSTEM

Step One:
Run the equipment to 250 hours then take an oil sample, change the oil, the factory full flow spin-on filter(s) and change the element in the FS-2500. This early first change is a “scrubbing” period that allows the FS-2500 to clean up the soot and sludge that is resident in the engine AND control the soot that the engine is producing at the same time.

Step Two:
Run the equipment to 250 hours, take an oil sample and change the element in the FS-2500 ONLY. Do not change the oil or the factory full flow spin-on filter(s). You now will have three oil samples on your engine; one before the FS-2500 was installed and two after the FS-2500 was installed. You are now developing a track record of your oil’s condition, your engine’s condition, and the performance of the FS-2500.

Step Three:
Run the equipment an additional 250 hours (now a total of 500 hours on the oil). Take an oil sample and change the element in the FS-2500 ONLY. When your oil sample results come in , take stock of the engine and oil condition and decide to either continue with the oil in your engine or change it (if oil analysis indicates the need to change the oil). Repeat step three every 250 hours until oil analysis indicates the need to change the oil or until you have reached your oil drain extension goal.

Step Four:
When oil analysis indicates that it is time to change your oil or when you have reached your target oil drain interval:
1. Change your oil.
2. Change your factory full flow spin-on filter(s).
3. Change the element in the FS-2500.
4. Start process over at step two and repeat until retirement!
