Peter, From the reading I have done this is like the Chevy vs Ford debate. (Well not really, I drive a chevy) You have to take the info and draw your own conclusions. Diesels water saturation point is around 60ppm at 70F, anything above this you get free water. If you are running a high quality fuel filter with aquabloc or similar synthetic material, it may be capable of removing most "free water" but not water that is saturated in diesel. My before and after fuel filter results on my Duramax showed water levels of 66ppm pre filter and 66ppm post filter. I took this as my water separator was not doing its job or it was full. I drained my filter and found two pea size water droplets in about 1L of fuel. After some investigation, I concluded that no filter is going to remove saturated water. I also concluded that I would need 2/3 of a cup of water in my Duramax filter for the Water In Fuel light to come on. This is not acceptable. The simple vibration of the truck will ensure water will pass into the injection system. This is NOT good. How often has a WIF light come on in your cruiser? I turned to additives. It is my understanding that an emulsifier chemically locks the free and saturated water in diesel fuel by surrounding it with a lubricant on a molecular level. Hence, when I did a future fuel analysis after running additives, we found no water in the fuel. If you want to do a neat experiment, take an ounce of fuel and an ounce of water and try to mix them together. It won't happen. Then add an ounce of diesel additive that emulsifies water. Kinda cool. If you can find a water in fuel test kit (sometimes available at big truck stops or bulk fuel distributors) tell us what you find;-) I'll betcha it's not water!! Further more, I added a 2 micron absolute filter to the truck post OEM filter to ensure I was receiving clean fuel at the injection pump. I have also done fuel analysis (particle size) with the dual filter set up with favorable results. The two worst things for your diesel are water and dirt.
