FS-2500 Filtration System


The FS-2500 is a remote mounted filtration system. The FS-2500 cleans your oil at an efficiency rate of 2.78 microns absolute. This will allow the end user to extend oil drain intervals dramatically, and most importantly, stop up to 99% of the wear in the engine.

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:


Step One:

Run the truck to 5,000 miles 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 truck to 10,000 miles, 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 truck an additional 10,000 miles (now a total of 20,000 miles 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 10,000 miles 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
