When fuel is refined all water is removed but in the transporting of fuel through the pipeline or from one tank to another, water accumulates. Fall and spring are the worst time for water build up with the warm days and cold nights causing fuel tanks to sweat. Many diesels are also using fuel heaters for winter operation and although they do help when running in the extreme cold they also create a lot of condensation as well as carbon build up and poor ignition. When water remains in your tank it will rust, corrode and create a slimy build up that will cause filter plugging and premature fuel system failure. Most products on the market today use an alcohol base and claim to remove water from the fuel , they do, however they may not remove the water from your tank .
Alcohol only combines with the water and settles it to the bottom of the tank where it remains.
By driving you cause agitation which can put large drops of water and alcohol in suspension long enough for them to be drawn into your fuel lines. This can cause thousands of dollars in damage. Water is a problem that needs to be addressed during the entire year, not just in the winter months. Locations your tank, but PFS fuel treatments adhere to the water and break it up into tiny droplets, encapsulating it in oil. It then holds it in suspension and disperses it safely a droplet at a time, and lubricates simultaneously.
