BIOBOR BBJUG01US BIOBOR JF DIESEL BIOCIDE GAL
Price: $189.79
Retail price is shown. * Add this item to the Shopping Cart to see your reduced price.

Product Description: Biobor JF Diesel Biocide, Gal. A liquid fuel additive that kills fungi, bacteria and micro-organisms in hydrocarbon fuels, such as diesel and jet fuels, but is also effective in light oils and transmission fluid. Is an effective micro-biocide because of its equilibrium solubility in both fuel and water under conditions of fuel storage. Also adds lubricity to low sulfur fuels that have been mandated by the EPA, bringing the lubricity in the fuel up to ASTM standards and allowing increased fuel efficiency.
