Biobor® JF has been the most widely used and recommended fuel biocide and lubricity additive for over 56 years. Recommended specifically by numerous major diesel engine manufacturers, Biobor JF will eliminate and prevent microbial growth in your fuel and dramatically increase the life of your filters. Additionally, Biobor JF adds lubricity back to ULSD, protecting your injectors and fuel pumps while also preventing corrosion.

Biobor® JF is a liquid fuel additive that combats fungus and other microbial life in hydrocarbon fuels, such as diesel and jet fuels, but is also effective in light oils and transmission fluid. Biobor® JF eliminates growth of harmful slime-producing fungi that clog filters and pipelines, attack rubber fuel system components and whose waste products aid in the corrosion of metal surfaces.
