Here is a sample of Mobil Delvac 1300 super from a CAT 3406E engine. This truck is owned and operated by Richard Pineda of Fort Collins, Colorado. Richard installed the FS-2500 filtration system on his truck in January of 2001. The latest sample on this report is from June 1, 2001, the mileage on this sample is 64,570 miles and CAT’s comments are all normal. For a sample at nearly 65,000 miles, the FS-2500 is redefining what can be considered normal.
CAT first took notice of Richard’s samples back in February of 2001 when he sent a sample in with 26,593 miles on it. When the sample was finished CAT sent him a note that said that the sample seemed too clean for oil with nearly 27,000 miles on it. Richard then told them that he was using the FS-2500 filtration system.
Caterpillars’s response was that they had never seen any filter that could safely extend oil drain intervals to these levels and that he should have his TBN tested. Caterpillar said that the TBN (Total Base Number) could not remain at acceptable levels using the FS-2500 and going this far on the oil; in fact they said that Caterpillar never wanted to see the TBN any lower than 4.5 to 5.0 and at 65,000 miles he was surely lower than that. At the bottom of this report you can see that Richards TBN was 8.0 at 65,000 miles using the FS-2500!
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 CAT 3406E sample with 64,000 miles on it to see for yourself if the additives have been stripped out.
