Fuel Shock is a dual phase oil soluble and water soluble potent broad spectrum biocide that is designed to prevent and control bacterial and fungal growth that can occur in diesel fuels, biodiesel fuels and home heating oils. Diesel fuels and home heating oils are often stored in conditions that can lead to intimate contact with water. Under these storage conditions the growth of micro-organisms can occur, producing dense masses that clog filters, pumps and fuel lines. Microbes also release organic acids which can accelerate corrosion of metals that can result in damage to storage tanks and fuel pumping equipment. Fuel Shock is designed to kill and control any microbial growth that is present in the diesel fuel or home heating oil.
