This is a sample from an Cummins ISM engine in a ready
mix truck owned by Lafarge Ready Mix. Before the FS-2500 filtration system
was installed, Lafarge changed their oil every 250 hours. Now they change
the oil between 700 and 1,000 hours. If you examine this sample, you can
see that all values are in order and the lab's recommendations are normal.
Filtration Solutions Worldwide recommends that the element in the FS-2500 be
changed at your normal oil drain interval (in this case 250 hours).
Lafarge has chosen to extend the element change past our recommended 250 hours
and is changing the element at 400 hours. Even though this sample is still
very good, we have customers using this same engine, in the same application,
that are getting 1,500 hours or more per oil change by changing the element in
the FS-2500 at the recommended 250 hours. Changing our element when your
oil would normally have been changed will give the best overall performance and
longest life from your oil and your engine.
We have customers tell us all the time that
Caterpillar has told them that the FS-2500 will strip the additives right out of
the oil, this of course is a false statement. Included on this page is a
virgin sample of Mobil Delvac 1300 Super. Compare these additives
(Magnesium, Phosphorus, Calcium and Zinc) to the ISM Cummins sample at 763 hours
to see for yourself if the additives have been stripped out.
