Prevents Sludge
Without a biocide you will get growth of microbial life in diesel fuel. The microb's die and leave sludge that will clog your filters and fuel system. I have used Biobor JF Microbiocide for several years with good results. Our boat is in southern Florida where it gets very humid in the summer. It's water in the fuel that gives the little critters a place to live. Its also a good idea to leave the fuel tank topped off, to leave less room for condensation to occur. Bill Bell
