Biobor JF diesel biocide and lubricity additive kills and prevents microbial growth (bacteria and fungi) including Hydrocarbon Utilizing Micro-organisms or HUM bugs which live in the water phase of a fuel tank and feed off of the fuel, causing clogged fuel filters and plug injectors. Dual-phase Biobor JF is soluble in both water and fuel phases for a more effective kill. Helps prevent corrosion of metal components and eliminate excessive sludge accumulation. In addition, Biobor JF helps restore lubricity levels, exceeding ASTM standards and protecting injectors and pumps from premature wear.
