Asphaltenes are formed when diesel fuel is heated under high pressure as it passes through today’s high pressure fuel injection systems. The drastic increase in pressure with these new fuel injection system combined with high temperatures actually cook the fuel and can create small pieces of tar about 2 microns in size — asphaltenes. These asphaltenes turn the fuel a dark brown color and can congregate and clog your fuel filters. They also can make up a significant part of the dark sludge that you see in many fuel storage tanks. The solids form a layer of tacky, gummy slime that grows over time and eventually must be removed.
Fuel Ox® offers a product designed to remove and prevent the formation of asphaltenes. Fuel Ox® Asphaltene contains ingredients that not only eliminate asphaltenes, but also prevent them from forming and turning fuel dark and sludgy.
