BIOBOR Diesel Fuel Additive — JF 8 oz Biocide & Lubricity Supplement, Dual-Phase Protection Against Microbes and Corrosion

BIOBOR JF is a concentrated diesel fuel biocide and lubricity supplement that kills and prevents microbial growth while restoring lubrication to protect injectors, pumps, and fuel tanks.

Designed and trusted by engine manufacturers, commercial operators, and the military for decades, BIOBOR JF treats the two most common fuel threats: waterborne microbes that form sludge and corrosive by-products, and the reduced lubricity in modern ultra-low sulfur diesel (ULSD). This 8-ounce bottle delivers a dual-phase chemistry that partitions between water and fuel to attack microbes where they thrive while replenishing lost lubricity to extend component life.

How does BIOBOR JF stop microbial contamination in diesel fuel?

BIOBOR JF contains biocidal agents formulated to reach both the water and fuel layers inside tanks, eliminating bacteria and fungi before colonies can form gel-like biomass. Regular dosing prevents new growth and reduces the solids that clog filters and foul injectors.

• Dual-phase chemistry targets microbes in both water and fuel phases
• Kills and prevents bacterial and fungal colonies that form sludge
• Reduces filter clogging and the need for emergency fuel polishing
• Limits acidic microbial by-products that accelerate tank corrosion

Will BIOBOR JF improve lubricity for modern diesel engines?

Yes — BIOBOR JF restores lubricating properties lost during ULSD refining, helping protect high-pressure injectors and fuel pumps from premature wear. Laboratory and industry testing show it increases lubricity to meet or exceed ASTM-related benchmarks used by engine manufacturers.

• Replenishes lubrication reduced by low-sulfur refining
• Proven to meet industry HFRR lubricity performance metrics
• Helps prevent premature injector and pump wear
• Suitable for fleet, marine, and stationary diesel systems

How do I use BIOBOR JF and how often should it be dosed?

Dosage depends on fuel volume and contamination level; a single 8-ounce bottle treats a defined number of gallons as directed on the label. For routine maintenance, treat at fill or on a scheduled basis; for contaminated systems, follow cleaning and shock-dose guidance to remove existing biomass.

• Follow label instructions for correct gallons-per-ounce dosing
• Routine preventative dosing at regular intervals reduces risk
• Shock dosing recommended for systems with active contamination
• Combine with filter checks and water-removal practices for best results

Can BIOBOR JF prevent corrosion and extend component life?

By eliminating microbial colonies and their acidic wastes, BIOBOR JF helps prevent the microbial-influenced corrosion that attacks tanks and metal parts. Combined with restored lubricity, treated fuel reduces wear on delivery components and prolongs filter life, lowering maintenance costs over time.

• Reduces corrosion from microbial acidic by-products
• Extends fuel filter life by preventing biomass buildup
• Protects metal components and preserves tank integrity
• Used historically by OEMs, airlines, and military services

Who is this for: BIOBOR JF is aimed at diesel engine owners and operators who need dependable protection against fuel contamination and wear — including fleet managers, marine operators, off-road equipment owners, aircraft ground fleets, and any user of ULSD who wants to minimize filter clogging, corrosion and injector/pump wear. Ideal for both preventive maintenance and remediation of microbial contamination, this product is the industry-recognized choice when consistent fuel quality and component longevity are priorities.
