FIS FUEL BIOCIDE EF is a specially designed liquid biocide against micro organisms contaminating fuel storage tanks and systems. These micro organisms can cause corrosion, clog filters and nozzles and degrade the properties of the fuel. FIS FUEL BIOCIDE EF is effective in the layers between water and oil where the growth of bacteria is most active.


FIS FUEL BIOCIDE EF is self-dispersing and can therefore be added directly to the fuel tank. Best results can be achieved by adding the FIS Fuel Biocide EF to the tank when 1/3 full before topping up with fuel.
