Hey guys. I got an fs2500 and thought you would like to know what I am seeing. Before I got this thing I would change my oil at 5000. At 5000 there was usually some oil loss. I assume the motor was burning a little as it got dirty. Well not any more. I have 5500 and the oil level has not declined at all, not even a little. There is no real discernible performance increase, but the engine is still running as smoothly as the day I changed the oil. You all Know what I mean. So far I am very happy with the product. And for all you guys looking at one of these. There is a REAL difference between the products. This FS2500 is a real tank. It must weigh 25lbs and it fits the Cummins perfectly. The guys at FS told me it is built like a tank because it was designed to be mounted on a Dozer or a Tractor where it might have to take a hit. I will be getting an oil test next week. I assume that the results will meet my expectations. I'll post the results.
