Draining Water
Has anyone ever observed a noticeable amount of water when draining from the separater valve? I try to do it each time I refuel, however all I ever see is pure diesel. I refuel from various stations and I doubt the quality is always the best. I have had two SD's 2010 and 2011 and never found water, is it possible it is there and not separated enough where it is not visually apparent? Almost seems to be a waste of fuel, but rather be safe than sorry..........

I've been more attentive to the water separator and have been careful to test overnight. I have yet to see ANY water, even a micro bubble whatsoever in any sample I have taken. Just for fun, I added water to a sample I drew out of the DFCM just to see what it looks like. Sure enough, a nice bubble of water on the bottom of the container. It would be very hard to miss if any water existed.

With the amount of fuel we are all burning, does anyone believe that there is zero water in any of the fuel we are using from different stations, suppliers all over the country? I don't. The only explanations I can come up with are (1) the water separator ain't working, or (2) the fuel pick up in the tank is such that the water is staying in our tanks, and not making it into the water separator to begin with. Any other ideas?

I have read of at least two instances where water was found in the separator. A small amount and not enough to set of a warning but visible water nonetheless. Maybe it's a good time to start a conspiracy theory here. Is it common practice for refineries to add emulsifiers and therefore shoot a bunch of unseparatable water through our fuel systems? Any takers?

I've never found water when draining on mine.
I only have around 21,000 miles but it has been driven across country twice so I am getting a mixture of fuel from different areas.

Adding an demulsifier, an emulsifier or a water solubilizer.
I'm not picking a side in the E vs. D debate. I've read articles on other diesel forums that Power Services says Diesel Kleen (grey bottle) and Diesel Fuel Supplement (white bottle) have no emulsifiers or demulsifiers, and that Diesel 911 (red bottle) has an actual solubilizer to counteract filter icing. That's what I use, I don't know what other brands have.

The WIF warning works on my truck....it came on 3-4 weeks ago. It was actually the first time I'd drained the separator. Unfortunately, I drained it into a dirty 5 gallon bucket, so I couldn't really tell if there was water there or not. But I drained it for about 45 seconds, started the truck and the warning was gone.

I guess I should have stated that differently. It doesn't necessarily mean the warning "works," but just that it came on one time because it was either past the threshold of water in the separator or it at least thought it was.
