How Has Ultra Low Sulfur Diesel Impacted Your Diesel Engine Performance?
Watch the video above to see how water in your fuel tank has become a breeding ground for "tank sludge" that will clog your filters and injectors.
New EPA Fuel Regulations
Since 2014, the EPA has mandated a reduction of sulfur in diesel fuel from 500 ppm (parts per million) to just 15 ppm.
As diesel is being transported from the refinery to your bulk fuel tank, it comes in contact with the air and naturally absorbs moisture. When diesel contained more sulfur, this was not a problem because sulfur acts as a surfactant and allows water to be held in the diesel solution.
However, ultra low sulfur diesel does not hold this moisture in solution. The result: water separates from the diesel and sinks to the bottom of your bulk fuel tank.
